SMD PTC resettable fuses provide compact overcurrent protection for electronic circuits and equipment. Their surface-mount design supports efficient PCB assembly and space utilization, while the PTC element increases resistance during excessive current or abnormal temperature conditions. After the fault is removed, the device can recover as it cools. Available in various hold currents, trip currents, voltage ratings, and package sizes, they suit power supplies, battery protection, USB ports, consumer electronics, communication devices, and industrial controls.
