POSISTOR r for Circuit Protection
Overcurrent Protection Narrow Current Band 140V Series
D max.
This product is a leaded type PTC thermistor
for overcurrent protection which is suitable for
a current limiting resistor.
c Features
1. Small ?uctuation in the circuit due to resistance
tolerance +/-10%
T max.

2. Narrow current range (less than twice) between
operating and non-operating current at -10 to
60 degrees C.
3. Quick operating time due to small size compared
with conventional products.
4. Best suited to meet the requirements for power
supplies and motor protection. Error-free operations
are assured by rush current.
5. Circuit is protected until current is turned off.
6. Restores the original low resistance value
automatically once the overload is removed.
7. Non-contact design leads to long life and no noise.
Durable and strong against mechanical vibration
and shock because it is a solid element.
