What is an Electronic Fuse?

An electronic fuse is a low resistance resistor that provides protection in the event of a load overcurrent. Short circuits, device failure or overloading can cause a load overcurrent. In an electronic fuse, a metal wire melts in the event of an overcurrent, therefore causing an interruption in the circuit.

Types of Electronic Fuses

There are many different kinds of electronic fuses and at Future Electronics we stock many of the most common types categorized by Maximum Working Voltage, Operating Temperature Range, Size, Current Rating, Packaging type and Response Characteristic. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for Maximum Working Voltage are 32 V, 125 V, 250 V and 600 V. We also carry electronic fuses with Maximum Working Voltage as high as 250000 V. Current Rating can be between 0.01 A and 500 A, with the most common electronic fuses having a Current Rating of 0.5 A, 1 A, 3 A, 4 A or 5 A.
