!Note
!Note
This chip PTC Thermistor is reflow soldering SMD type
for overheat sensing for power transistors, power
diodes and power ICs in hybrid circuits.
1. SMD type is helpful for miniaturizing circuits
2. Excellent thermal response due to small size
3. Solid-state construction provides excellent
4. Contactless operation provides noiseless operation.
5. Lead is not contained in the terminations.
