## **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. ## **Mounting** The thermistors are suitable for automatic placement. ## **Marking** The components are supplied unmarked. ## **Packaging** Tape/reel - 5k pcs/reel. Dimensions are shown for reference purposes only. Dimensions are in Specifications subject to tycoelectronics.com millimetres unless change. passives.tycoelectronics.com otherwise specified.
