Non-Resettable Surface Mount Fuses

Non-resettable surface mount fuses are single-use circuit protection devices that break a circuit when a fault is detected. This type of fuse is designed to be mounted directly onto a printed circuit board (PCB).

How do non-resettable surface mount fuses work?

Non-resettable surface mount fuses perform the role of a simple circuit breaker in a circuit. When a fault such as overcurrent or a short circuit is detected, the metal strip inside the fuse melts, stopping the flow of current and preventing damage to the circuit and any other connected devices. Once the fuse has blown, it must be replaced as it is non-resettable.

Types of non-resettable surface mount fuses

Non-resettable surface mount fuses can differ by their voltage and current rating, their size and their level of resistance, measured in ohms. Their body material can also vary widely, from thermoplastic to glass ceramic. This type of fuse can have a range of maximum and minimum operating temperatures.
