Resettable Circuit Fuses
Repeated use available, so no need to replace each time
The PTC thermistor P.R.C.P. series that used polymer for the resistance element is also surface mount type in a rich line-up, is the most suitable over-current protection devices for the Hot Plug condition interface at plug and play and others, because the time to trip is slow properly, and it does not respond at surge-current or rush-current condition.
On the other hand, C-FAP series, the integrated type of MOSFET and current detection circuit has a high-speed response characteristics within 1 μsec.
