PTC Resettable Fuses

PTC resettable fuses are polymeric positive temperature coefficient devices, they are passive electronic component used to protect against overcurrent faults in electronic circuits

PTC resettable fuse is also known as a multifuse or polyfuse or polyswitch. While cold, it will pass a current, if it’s rated current is passed through the device it will begin to heat rising the resistance of the device. This increase in resistance substantially reduces the current in the circuit.
