Eaton’s PTSA family of resettable PTC fuses are polymeric positive temperature coefficient overcurrent protection devices. They offer low resistances and fast time-to-trip performance with hold currents ranging from 100 mA to 2.6 A and voltage ratings above 13 V ideal for typical automotive circuitry. These fuse families are all offered in four surface-mount printed circuit board (PCB) footprints from 0805 up to 1812 with AEC-Q200 qualification.
The PTSAHT are a select group of high-temperature PPTCs capable of withstanding operating temperatures up to +125 °C and offer hold currents from 100 mA up to 500 mA.
