!Note
This product is a leaded type PTC thermistor
for overcurrent protection which is suitable for
a current limiting resistor.
1. Small fluctuation in the circuit due to resistance
2. Narrow current range (less than twice) between
3. Quick operating time due to small size compared
4. Best suited to meet the requirements for power
5. Circuit is protected until current is turned off.
6. Restores the original low resistance value
7. Non-contact design leads to long life and no noise.
