Type NTC Series
A range of NTC chip thermistors
offering high thermal sensitivity.
Suitable for temperature compen-
sating circuits and other applica-
tions requiring a resistance
that varies according to ambient
temperature.

Mounting
The thermistors are suitable for automatic placement.
Marking
The components are supplied unmarked.
Packaging
Tape/reel - 5k pcs/reel.
Power Rating and Maximum Operating Temperature
The power rating is specified at an ambient temperature of 25°C. Under these conditions, the temperature of the
thermistor element reaches its permitted maximum temperature of 125°C. The thermistor should be derated
linearly from 100% at +55°C to zero at 125°C as shown in the derating curve.
