Resistor Pairs and Quads with Ratio Characteristics for Precision Analog Circuits

Type T912 and T914 Precision Resistor Networks are constructed with

Caddock Tetrinox resistance films to achieve the precise ratio performance

and stability required by highly accurate amplifier circuits, voltage reference

circuits and precision bridge circuits.

Ratio Tolerance - from 0.1% to 0.01%.

Ratio Temperature Coefficient - 10 ppm/°C, 5 ppm/°C or 2 ppm/°C.

Absolute Temperature Coefficient - 25 ppm/°C.

Ratio Stability of Resistance at Full Load for 2,000 hours - within 0.01%.

Shelf Life Stability of Ratio for 6 Months - within 0.005%.

Both the T912 and the T914 are available in 14 standard resistance values

between 1,000 ohms and 1 Megohm. Caddock's high thru-put manufacturing

capability assures that prototype and large-volume production quantities are

available either from stock or within 6 weeks after receipt of order.

Now with Extended Resistance Range to 10,000 Megohms and Additional Models

Temperature Coefficient as tight as 80 ppm/°C, Combined with Excellent Long-Term Stability and Precision Tolerances.

Caddock's Micronox

resistance films are the source of

the Type MG Precision High Voltage Resistors' outstanding

combination of performance features:

Single-resistor values as high as 10,000 Megohms.

Maximum continuous operating voltages as high as

48,000 volts ("-15" ratings).

Overvoltage capabilities of 150% of standard working

voltages for all models and values, (except "-15" ratings).

Resistance Tolerances from ±1.0% to ±0.1%.

Temperature Coefficient, for standard resistance range, of

80 ppm/°C in combination with resistance tolerances as

tight as ±0.1%.

Type MG resistors have demonstrated stability of 0.01%

per 1,000 hours in extended load life testing of standard

resistance range values.

This exceptional performance has been proven through

many years of use in equipment that demands the highest

reliability and stability, including TWT amplifiers, X-ray

systems, geophysical instruments, and medical electronics.

Preconditioning for Power and Voltage Ratings

All power ratings and maximum operating voltage ratings

are for continuous duty. These ratings are based on pre-

stress voltage levels applied during the manufacturing

process to provide for stable resistor performance even

under momentary overload conditions.

Maximum operating voltages 60% higher than the values

listed in the table may be specified by adding "-15" to the

model number (Example: MG750-15). Note that overload

and overvoltage ratings do not apply to the "-15" resistors.

Resistance ranges for "-15" resistors shown in the table are

from "-15 Min." to "Standard Max."

Non-Inductive Performance

Most models are manufactured with Caddock's

Non-Inductive Design which uses a serpentine resistive

pattern that provides for neighboring lines to carry current in

opposite directions, thereby achieving maximum cancellation

of flux fields over the entire length of the resistor. This

efficient non-inductive construction is accomplished without

derating of any performance advantages.

Insulation Resistance: 10,000 Megohms, min.

Overload/Overvoltage: 5 times rated power

with applied voltage not to exceed 1.5 times max-

imum continuous operating voltage for 5 seconds

Temperature Coefficient as tight as 80 ppm/°C, Combined with Excellent Long-Term Stability and Precision Tolerances.

Caddock's Micronox

resistance films are the source of

the Type MG Precision High Voltage Resistors' outstanding

combination of performance features:

Single-resistor values as high as 10,000 Megohms.

Maximum continuous operating voltages as high as

48,000 volts ("-15" ratings).

Overvoltage capabilities of 150% of standard working

voltages for all models and values, (except "-15" ratings).

Resistance Tolerances from ±1.0% to ±0.1%.

Temperature Coefficient, for standard resistance range, of

80 ppm/°C in combination with resistance tolerances as

tight as ±0.1%.

Type MG resistors have demonstrated stability of 0.01%

per 1,000 hours in extended load life testing of standard

resistance range values.

This exceptional performance has been proven through

many years of use in equipment that demands the highest

reliability and stability, including TWT amplifiers, X-ray

systems, geophysical instruments, and medical electronics.

Preconditioning for Power and Voltage Ratings

All power ratings and maximum operating voltage ratings

are for continuous duty. These ratings are based on pre-

stress voltage levels applied during the manufacturing

process to provide for stable resistor performance even

under momentary overload conditions.

Maximum operating voltages 60% higher than the values

listed in the table may be specified by adding "-15" to the

model number (Example: MG750-15). Note that overload

and overvoltage ratings do not apply to the "-15" resistors.

Resistance ranges for "-15" resistors shown in the table are

from "-15 Min." to "Standard Max."

Non-Inductive Performance

Most models are manufactured with Caddock's

Non-Inductive Design which uses a serpentine resistive

pattern that provides for neighboring lines to carry current in

opposite directions, thereby achieving maximum cancellation

of flux fields over the entire length of the resistor. This

efficient non-inductive construction is accomplished without

derating of any performance advantages.

Insulation Resistance: 10,000 Megohms, min.

Overload/Overvoltage: 5 times rated power

Resistance Tolerances from ±1.0% to ±0.1%.

Temperature Coefficient, for standard resistance range, of

80 ppm/°C in combination with resistance tolerances as

tight as ±0.1%.

Type MG resistors have demonstrated stability of 0.01%

per 1,000 hours in extended load life testing of standard

resistance range values.

This exceptional performance has been proven through

many years of use in equipment that demands the highest

reliability and stability, including TWT amplifiers, X-ray

systems, geophysical instruments, and medical electronics.

Preconditioning for Power and Voltage Ratings

All power ratings and maximum operating voltage ratings

are for continuous duty. These ratings are based on pre-

stress voltage levels applied during the manufacturing

process to provide for stable resistor performance even

under momentary overload conditions.

Maximum operating voltages 60% higher than the values

listed in the table may be specified by adding "-15" to the

model number (Example: MG750-15). Note that overload

and overvoltage ratings do not apply to the "-15" resistors.

Resistance ranges for "-15" resistors shown in the table are

from "-15 Min." to "Standard Max."

Non-Inductive Performance

Most models are manufactured with Caddock's

Non-Inductive Design which uses a serpentine resistive

pattern that provides for neighboring lines to carry current in

opposite directions, thereby achieving maximum cancellation

of flux fields over the entire length of the resistor. This

efficient non-inductive construction is accomplished without

derating of any performance advantages.

Insulation Resistance: 10,000 Megohms, min.

Overload/Overvoltage: 5 times rated power

with applied voltage not to exceed 1.5 times max-

imum continuous operating voltage for 5 seconds

Type 1: DC Voltage

Type 2: DC Voltage or V

Thermal Shock: Mil-Std-202, Method 107,
