SF-0603SP100M-2

Application Field and Working Principle

SF-0603SP100M-2 is a current limiting fuse, which is a kind of over-current protection device used mainly for over-current protection of electronic circuits. It works mainly by breaking the circuit when current is over-loaded and the heat generated by the current and by breakdown is sufficient to melt the fuse element. It can protect the circuit from over-current and is a kind of useful and important for our electronic circuit protection devices.

Application Field

The SF-0603SP100M-2 can be used in various electronic products, such as mobile (cell)phones, notebook computers, LCD TVs, audio-visual systems, etc. It is mainly used for the short circuit or over current protection of these electronic products. It is mainly used in circuit boards and power distribution devices such as distribution boxes.

Working Principle

SF-0603SP100M-2 works based on the principle of thermal melt meltdown because of joule heating caused by over-current. It consists mainly of a metal fuse element and sleeve, which will melt when an over current situation occurs. When current flows through the fuse element, the generated heat will be stored in the element, as the current increases, the temperature of the element will increase, when reaching a certain temperature, the fuse element will melt down, leading to the disconnection of the fuse element, thus achieving the effect of current limitation and circuit protection. After the fuse element melts, the current is cut off until the element is replaced.

The SF-0603SP100M-2 fuse has high current limiting accuracy, low temperature coefficient, and low contact resistance. The breakdown voltage is less than 2V when the rated current is reached, it is more suitable for digital appliances, which are sensitive to instantaneous voltage. It can limit the current in time and effectively protect electronic products.

Conclusion

The SF-0603SP100M-2 is a current limiting fuse mainly used in electronic products such as mobile phones, notebook computers, LCD TVs, audio-visual systems, etc. for short circuit or over current protection. It can stop the instantaneous over current in a timely manner and effectively protect electronic products. The fuse element is simple in structure, made of metal and has high current limiting accuracy, low temperature coefficient, and low contact resistance.
