F0603G0R12FNTR Circuit Protection

F0603G0R12FNTR Application Field and Working Principle

Fuse is an important protection device in the electrical system. It can quickly cut off the circuit and protect the system when the circuit is overloaded or short circuit occurs. F0603G0R12FNTR is a billet axial fuse which has wide application field and long-term current combination.

Application Field

F0603G0R12FNTR is an axial fuse and widely used in the general electrical system, such as signal control systems, circuit boards, household appliances, LED lighting, etc. It is designed with fast blow which can effectively protect the system in the over current and short-circuit conditions. The operating temperature of this type of fuse is from -55°C to 125°C, so it can work in wide range of ambient temperatures easily.

Working Principle

F0603G0R12FNTR works based on the principle of melting of the conductor. It can quickly cut off the circuit through melting copper wire in the fuse and remove or reduce the current overload. The wire in the fuse has fast blow characteristic, thus it can protect the circuit and electrical system quickly and precisely. In the normal state, current will pass through the fuse wire and the circuit will operate normally. When the current rises to its set value, the fuse wire will melt and the circuit will break, thus achieving the protection effect. After fuse blows, it needs to be a replacement to be used normally.

Features

F0603G0R12FNTR has advanced working principle and features. It features high temperature stability, low power consumption and high reliability. The contact resistance is low and the internal contact material is designed with nickel-plated brass. Moreover, it has strong anti-vibration and anti-interference, so it can work normally and stably in the harsh environments. This type of fuse can withstand high power and would not easilydamaged by over voltage, so it can protect the circuit safety even with sudden usage changes.
