SF-0603SP063-2 Circuit Protection

Fuses

SF-0603SP063-2 is a type of fuse from the family of SFF. It is a surface mount device and designed for telecommunication applications. The fuse has a high response time of 0.25 second with interrupt rating of 240 A at 75 VAC. The small size and low profile makes it ideal for space-constrained commercial applications.

Application Fields

SF-0603SP063-2 fuses can be used in applications such as power supplies, automotive electronics, audio-video applications, computer and peripherals, household appliances, telecom and industrial electronics. It is commonly used as safety protection against overload and short circuit in high reliability applications.

Working Principle

SF-0603SP063-2 fuses operate on the principle that some specialized metals, when subjected to excessive current, vaporize quickly and opens the circuit to protect the electronic components. The melting point of the metal strip is determined by the manufacturer according to the desired current rating. The melting of the metal strip occurs within a few milliseconds and the circuit is opened when the current exceeds the preset rating.

SF-0603SP063-2 fuses are rated to withstand the short-circuit current and over-current events without deteriorating. They also prevent sparking and minimize thermal stress on components. As they are made of a special low-temperature thermoplastic material, they do not generate toxic or hazardous gases when subjected to high temperatures.

Advantages

The primary advantages of SF-0603SP063-2 fuses is that they are small in size, have
