Silicon Spreading Resistance Temperature Sensor in
Miniature Leaded Plastic Package
KT 110, KT 210,
KTY 11, KTY 21
Features
Temperature dependent Resistor with Positive
Temperature Coefficient
Miniature plastic package for very small thermal time
constants
Fast response
High reliability due to multilayer gold contacts
n-conducting silicon crystal
Polarity independent due to symmetrical construction
Available selected in
1% tolerance groups (KTY-series)
1)
ESD Class 1. When the temperature sensor is operated with long supply leads, it should be protected through
the parallel connection of a > 10 nF capacitor to prevent damage to the sensor through induced voltage peaks
