## Description

Resettable fuses (PTC thermistors) protect your circuits against overcurrent faults by automatically limiting current flow when the trip threshold is exceeded. Unlike traditional fuses, they reset themselves once the fault is removed and the fuse cools down — no replacement needed. Place them on the power input of your circuit for an extra layer of protection against shorts and miswiring. How They Work When current exceeds the trip rating, the fuse heats up, causing its resistance to increase dramatically. This reduces current flow through the circuit, protecting downstream components. Once the overcurrent condition is removed, the fuse cools and returns to its low-resistance state. Specifications (500mA) Hold Current: 500mA Trip Current: 1A Max Current: 40A Max Voltage: 60V Ideal For Power input protection on circuit boards Protecting against short circuits and miswiring USB and battery-powered projects Any application needing reusable overcurrent protection Resources Datasheet — 500mA (PDF)
