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