The 0SFE004.V is an electronic fuse mainly used in automotive applications and is characterized by its small size and fast reacting time. This type of fuse is specifically designed to protect electrical and electronic circuits from being damaged due to an overload or short circuit.

Applications

The 0SFE004.V fuse is mainly used in automotive applications but can also be used in other consumer and commercial electronics such as cell phones, video players, television, and computers. It is particularly used to protect circuits from being damaged due to an overload or short circuit, preventing circuit breakers and other fuses from triggering and damaging the circuit further. As it is a very small and lightweight fuse, it is also ideal for use where space is a limitation.

Working principle

The 0SFE004.V fuse is an electronic fuse that uses a Metal-Oxide Varistor (MOV) as the main component. The MOV has two terminals that are connected to the circuit and a sensing capacitor that detects when the current flow is out of limits. If the current flow exceeds the safe levels, the MOV will heat up and in turn, blow the fuse. This thermal action helps protect the circuit from any short circuits or overloads and prevents any additional damage to the circuit. The sensing capacitor helps detect any changes in the current flow in order to react quickly and blow the fuse when needed.

Advantages

The 0SFE004.V is a highly reliable and versatile fuse that can be used in a variety of electronic applications. This type of fuse is relatively inexpensive and surprisingly robust compared to other standard fuses, as it can handle current surges of up to 10,000A. Its small size also makes it ideal for use in applications where space is a limiting factor. Additionally, the fuse has a fast reacting time due to its sensing capacitor and is designed to blow quickly and protect the circuit from further damage.

Disadvantages

The main disadvantage with the 0SFE004.V is that it is a single-use product which means that it cannot be reset and must be replaced after it has been blown. Additionally, although the MOV that powers this type of fuse is highly reliable, it can suffer from moisture damage if exposed to humid environments.
