POSISTOR

r for Circuit Protection

Overheat Sensing Chip Tight Tolerance Type

This chip PTC Thermistor is a reﬂow soldering SMD type

for overheat sensing for power transistors, power

diodes and power ICs in hybrid circuits.

c Features

1. SMD type is helpful for miniaturizing circuits

because of its small size and light weight.

2. Excellent thermal response due to small size

3. Solid-state construction provides excellent resistance

to mechanical vibration and impact resistance.

4. Contactless operation provides noiseless operation.
