Automotive SMD Resettable Fuses

Littelfuse PolySwitch® Family of Automotive SMD Resettable PPTCs are designed to support the miniaturization trend in automotive electronics. These devices meet performance specifications for resistance, time-to-trip, and hold current at three temperatures (-40°C, 25°C, and max T). These parts are AEC-Q200 qualified, RoHS compliant, ELV compliant, lead free, and halogen free as well as ISO/TS16949 certified. Littelfuse automotive PPTCs provide current ratings from 0.05A to 3.0A and voltage ratings from 5V_DC to 60V_DC. These devices provide overcurrent and overtemperature protection for Electronic Control Units (ECUs), I/O ports and traces, telematics and infotainment systems, and motor and motor control circuits. Littelfuse Automotive SMD Resettable PPTCs are compatible with high-volume SMD assembly processes.
