THERMISTOR
"Thermistor" is the generic name given to
thermally sensitive resistors.
Negative temperature coefficient thermistor
is generally called as thermistor. Thermistor
is a semiconducting ceramic resistor
produced by sintering the materials at high
temperature and made mainly from metal
oxide.
Depending on the manufacturing method
and the structure, there are many shapes
and characteristics for various purposes
such as temperature measurement,
temperature compensation and etc.
The thermistor resistance values, unless
otherwise specified, are classified at a
standard temperature of 25 C.
B constant is calculated from the resistance
values at 25 C and 85 C.
The resistance of a temperature is solely a function
of its absolute temperature. Since electrical power
being dissipated within a temperature might heat
above its ambient temperature and thereby reduce
its resistance, it is necessary to test for resistance
with temperature. The resistance so measured is
called RT, which means the resistance at essentially
zero-power.
The mathematical expression which relates the
resistance and the absolute temperature of
a thermistor is as follows:

Where:

B is a constant which depends on the
material of the thermistor
Unless otherwise specified,all values of B are
determined from measurements made at 25 C and
85 C.
The temperature coefficient of resistance
is expressed in the follow ing equation:
100 (%/ C)
Resistance -Temperature Characteristics
Dissipation factor
Thermal time constant
Dissipation factor ( ) is power in milliwatts
required to raise thermistor temperature 1 C.
Measured with thermistor suspended by its leads in
a specified environment.

thermistor to change 63% of the difference between
its initial and final temperature. Measured with
thermistor suspended by its leads in specified
environment.

HT thermistors are entirely new type of thermistor
for surface mounting (by reflow soldering) and were
acquired from advanced technology.
Our HT thermistors are adapted metal electrodes
packaged in a resin mold, unlike conventional chip
thermistors, and can offer 2% tolerance for a
resistance value at 25 C.
HT series (SMD Thermistor) is not only compact-
surface mounting type but also highly accurate and
reliable.

POWER
THERMISTOR
The POWER THERMISTOR is a device for
suppressing inrush current to an electric
circuit. Circuits including electric bulbs or
capacitors induce a inrush current more
than 100 times the normal current when the
circuit switch is turned on. The POWER
THERMISTOR in the circuits protects
electric equipments from being damaged
by limiting the inrush current.
MARK is a NEW POWER THERMISTOR
featuring smaller size and larger energy
capacity to meet severe requirements in
inrush current suppression.
There is the tendency of miniaturization in
low power switching power supply, and
MARK is effectively applicable for the
needs, though the comparatively larger
sized fixed resistors (ceramic coat) are
used now.
Application
How to use the power thermistor
The power thermistor will suppress inrush current
which is caused by a capacitor, filament for a bulb,
inverter for fluorescent lamp, a heater and etc., also
will control fan motor speed of cooler for electric
circuit.
Especially MARK was developed to use for power
supply of TV, VCR instead of cement resistor.
Accordingly, suitable thermistors are 6D-22, 5D-18
and 8D-18, and if we consider in the points of small
time constant which means a small size and large
effect for suppressive current which means large
rated zero-power resistance, 8D-18 is the most
suitable one.
Use the following circuit in the power supply for 100V
and 200V.
The most suitable power thermistor for the above
circuit is required to fulfill the following terms and
conditions.
1. The permissible current at ambient temperature of
55 C should be over 2A.
2. The thermistor resistance for suppressive current
which becomes below 30A should be over 4.2
ohm from the under-mentioned formula.

Thermal time constant
If ambient temperature of a thermistor is changed
to T
1
from T
2
suddenly, temperature of the thermistor
changes slowly.
The time constant means the time when temperature
of the thermistor reaches 63% of the temperature
difference.
Maximum permissible current
If the maximum permissible current flows to a
thermistor at 25 C, temperature of the thermistor
rises to 200 C, (160 C). When ambient temperature is
above 25 C, the maximum permissible current shall be
over reduced as the maximum permissible current
reduction curve.

Residual resistance
If current is flowed through a thermistor, any heat
will be generated in the thermistor by which its
resistance will be decreased, however, a decrease
of a resistance will be stabilized at a saturation
resistance value which is determined by impressed
electric power and a dissipation constant. The
residual resistance value means maximum
saturation resistance value when the maximum
permissible current is flowed through the thermistor.
Temperature coefficient
The temperature coefficient of a thermistor is
expressed by the following equation ;
Dissipation factor
If small voltage is applied to a thermistor, small
current will flow which produce enough heat in the
thermistor. Dissipation factor is electric power
which make 1 C raise by heat in a thermistor.
Resistance-temperature characteristics
The theoretical characteristics of a thermistor is expressed by following equation.
P is applied electric power.
t is rised temperature of the thermistor.

TRANSIENT VOLTAGE SUPPRESSOR
VRD
VRD is a transient voltage
suppressor used for protecting electric
circuits from surge voltage and thus
preventing breakdown.
VRD has superior surge suppression
characteristics, such as extremely fast
response time, very low clamping voltage,
and high surge capacity. Unlike metal oxide
varistors, VRD does not have characteristics
to change with surge variations within the
rated capacity. This feature comprises
another superior characteristics of the VRD
as a transient voltage suppressors.
Electrical characteristics
Figure 1 shows the electrical characteristics. Bipolar
type has almost symmetrical breakdown Voltage (V
B
)
Surge capability
Allowable surge capability (Pm) is determined by the
following equation:
Pm Ip V
C
Ip:Peak current
Vc:Maximum clamping voltage
The allowable surge capability (peak pulse power) of
VRD is shown in following Figure 3 and the surge ca-
pability derating characteristics are shown in Figure 6.
Surge suppression characteristics
Power derating
When EXP waveform is applied to the circuit
below, the surge suppression waveform shown in the
figure 5 can be observed.
Surge waveform
There are many types of surge waveform depending
on the source of the surge. For the VRD surge
suppression characteristics test, the EXP waveform
shown below is used. The EXP waveform is shown as
ta / tb depending on the time width, however 10/1000
waveform is used as the standard test waveform.
The reverse breakdown voltage of the ZD type is 200
Volts or more at 10 A DC.
Taping
One of standard taping is as shown in Figure.

Features
METAL OXIDE VARISTOR
ZENAMIC
ZENAMIC is the product name of a metal
oxide varistor.
ZENAMIC Transient / Surge Absorber, Series
D is newly released through our continued
research in ceramic material composition of
ZnO varistor and manufacturing process,
featuring large surge current handling
capability and energy handling capability
for absorbing transient overvoltage in
compact size.
Improved in "Surge Current Handling
Capability (@8 / 20 s, 2 times)" by about 2
times over the current.
Very large "Energy Handling Capability"
absorbing transient overvoltages in
compact sizes.
Lower Clamping Voltage for better surge
protection.
Fast response to high speed transient /
surge voltage.
Wide products range for transient / surge
protection on AC 100V to AC 480V
nominal system with the maximum peak
current ratings of 600A to 7000A (@8 / 20
s, 2 times).
33
ZENAMIC has the forward-reverse symmetrical
electrical characteristics as shown in the figure 1.
The voltage-current curves show the varistor
characteristics in the range 1 A to 10
4
A, and show
the resistance characteristics for the range under
1 A and over 10
4
A in the figure 2.
The voltage across terminals when test current(It:
1 mA)is applied to ZENAMIC is the standard varistor
voltage(Vz), and the voltage across terminals when
a standard surge(Ip) is applied represents the
maximum suppression voltage(Vc).

V- characteristics
A surge waveform varies according to the sources.
An EXP waveform is used for surge testing of
ZENAMIC, while a AC half-wave is used for the
energy absorption test. The EXP waveform reaches
its peak voltage (current) at [ta] as shown in the
figure 5, and then decreases as time passes and
reaches half of the peak voltage (current) at [tb].
This type of the EXP waveform is shown as a [ta / tb]
voltage (current) waveform. For surge testing
of ZENAMIC, the 8 / 20
sec current waveform is
used.
Surge waveform
Power lines and surge absorption units with error
display (SA series).
Applications
In the small current range, ZENAMIC features
outstanding temperature characteristics. A shunt
resistance Rp of metal oxide varistor has the
temperature characteristics which is determined by
the following equation.
Temperature characteristics
1.A surge excess of the specified Maximum Peak
Current may cause short circuit or mechanical
damage. The following measures are recommended.
In case that ZENAMIC is used in line to ground, the
ground fault circuit interrupter shall be applied in
location A or thermally coupled fuse shall be
applied in location C.
ZENAMIC shall not be used near heat generating
device and free from direct sunlight.
ZENAMIC shall not be used near the flammable
materials.
1) Location of the over current protector(circuit breaker
or current fuse)shall be in the power line to the
circuit(Location A)or in series with ZENAMIC
(Location B).
2) It recommended that a fuse listed in the table be put
in location A or B.
3) In case that ZENAMIC is used in line to ground, the
ground fault circuit interrupter should be applied in
location A or thermally coupled fuse should be applied
in location C.

GASTUBE
ARRESTER
Gas tube arrester(GTA)is a surge absorber
featuring low capacitance and high surge
absorption energy.
lt consists of a sealed tube in which inert
gas is injected and electrodes which are
set at fixed intervals. The simple structure
and the dimensional accuracy offer high
reliability and stabilized characteristics.
Applications

1. Protection for telephone set, facsimile, telex,
telephone system, CATV, computer and peripheral
equipment.
2. Semiconductor circuit protection in equipment
that also uses high voltage such as TV,
oscilloscope, and electron microscope.
3. Automatic control of luminous energy in
stroboscopic tube.
4. Generator of high-voltage for gas igniter.

The current through the GTA is changed over the
range of values of 10
18
to 10
2
amps which is shown
as the figure below and the voltage across the GTA will
also valy.The discharge characteristics are changed to
various mode by the flowing current, and the final
mode of the discharge characteristics is arc discharge .
When the applied voltage across the GTA exceeds
the breakdown voltage (sparkover voltage), the
current through the GTA increases rapidly to value
of several amps or greater. The rate of current rise and
level to be reached are limited by the series impedance
of the circuit.The voltage across the GTA at this
time is very low with typical value of 20 to 30 volts.
The current is the rms value of sinusoidal alternating
current of 50Hz or 60Hz which can flow through the
GTA in accordance with a certain test method without
substantially altering its sparkover voltage. The
usual test consists of specified loads applied for 1
sec at interval of 1 min alternately. ln the test of the
maximum AC discharge current, the GTA is applied
9 cycles of 50Hz AC(180 ms) continuously.
The life is defined as the minimum number of surges
of a certain current waveform the GTA can survive
without deterioration of its operating specifications.
This is defined as the resistance value across the
terminal of GTA at 100V
DC
for devices over 230V
DC
(140V
DC
for GTA type) breakdown voltage and 50V
DC
for devices less than 230V
DC
(140V

for GTA type)
ratings.
The voltage is the minimum slowly rising DC voltage that
will cause sparkover when applied across the terminal
of the GTA.The GTA shall be placed in darkness for
at least 15 min and tested in this condition using a
ramp voltage waveform with 100V/s to 500V/s.
The GTA shall be tested with a positive and a
negative waveform. The sparkover current for DC
sparkover voltage test shall be within 10 amps.
The GTA to be exposed to the test shall be kept in
total darkness before (for at least 15 min) and during
the test. Then, with a ramp voltage with 5kV / s
applied to the GTA, the breakdown voltage level is
recorded. ln case of testing with opposite polarity,
using the same GTA, a minimum of 15 min shall
elapse.
This test is to determine the ability o f the GTA t o
conduct a maximum single impulse Discharge
current. The current impulse waveform is 8 / 20
s.
The maximum single impulse discharge current
is the crest
current of the impulse.
This values is defined as the maximum DC voltage
across the t erminals of the GTA which is expected
to clear and restore its high impedance state within
150 ms or less after the passage of a surge.
The capacitance of the GTA is defined as
capacitance across terminals of the GTA at 1 kHz.
20 C 65 C
lmpulse breakdown voltage is the voltage at which
the GTA fires when the voltage increases at rates
of more than 100V/ s. This value may not vary even
after the GTA has been stored in the dark for long
period. The value of the impulse breakdown voltage
increases with increasing steepness of the surge
voltage as the figure below.
