Fuses

Fuses are one of the most essential components of an electrical system, providing protection against electrical power distribution equipment in cases of quiescent fault current or transient fault current. SF-0402F075-2 is a miniature fuse widely used in consumer and commercial applications for over-current protection.

Application Field

The SF-0402F075-2 is a quick blow, surface mount fuse, 1206 size (3.2mm x 2.5mm x 2.75mm) with a current rating of 75A. It typically finds application in charging port protection for various mobile devices, over-current protection for DC and AC converters, 3D printer boards, communications equipment, consumer electronics, and many other circuit designs.

Working Principle

Normally, a fuse is simply a conducting material which is designed to melt in response to an over-current fault. SF-0402F075-2 is made of a silver-alloy wire as its element. When the circuit current exceeds the rated current, the element melts open, thus stopping the current from flowing and protecting the device. The element will reconnect the circuit once it cools and the over-current is removed.

Conclusion

In conclusion, SF-0402F075-2 miniature fuse is a quick blow, surface mount fuse widely used in consumer and commercial applications for over-current protection. It has a current rating of 75A, typically finding application in charging port protection for various mobile devices, over-current protection for DC and AC converters, 3D printer boards, communications equipment, consumer electronics, and many other circuit designs.
