SMD Polymer PTCs for Overcurrent Protection

Vishay / BC Components SMD Polymer PTCs for Overcurrent Protection are designed for use as resettable fuses for low-voltage overcurrent protection applications for industrial and consumer products. These polymer-based PTC SMD thermistors protect against temporary, infrequent overcurrent events and are UL 1434 and TÜV certified. The PPTC series offers ultra-low initial resistance with many values <1Ω and can be as low as 0.005Ω at +25°C. These PPTCs protect the circuit by tripping into high resistance during an overcurrent event, causing the PTC to heat up. Note that the PPTC expands slightly when tripped. The PPTCs return to a lower resistance (though not as low as the pre-trip resistance) once the fault is removed and the PPTCs cool.
