Fuses

Fuses are electrical circuit components that are designed to protect electrical devices from damage due to excess air current or overloads. By allowing a limited amount of current to flow through the circuit, fuses save energy and protect downstream components from dangerous levels of voltage. In today’s modern world, electrical fuses have become commonplace components in a variety of applications, including residential, commercial, industrial, and automotive. One particular type of fuse, the 7100.0190.71, is gaining popularity owing to its versatility and advantageous design.

7100.0190.71 Application Field

The 7100.0190.71 is a type of ceramic body fuse that is most commonly used in automotive, military, and aviation electronics. This fuse has been designed to protect printed circuit boards, backplanes and power components from electrical overloads, as well as from short circuits that can cause irreparable damage to the devices. In addition, the 7100.0190.71 can also be utilized in laboratories and test benches to provide protection against accidental short circuit conditions. The 7100.0190.71 fuse also acts as a switch in certain applications where the system needs to be powered off after the circuit has triggered the fuse.

7100.0190.71 Working Principle

The 7100.0190.71 ceramic body fuse operates based on its solid state design. Its two-terminal design has two electrodes which are separated by a special ceramic material. The fuse is designed with a specific current rating, and when the current passing through the fuse exceeds the rating, it will create a thermal imbalance that will cause the ceramic material to expand. This expansion will cause the electrodes to touch each other, effectively short-circuiting the system and tripping the fuse. After the current overload has been dealt with, the fuse can be reset and the system will return to normal use.

Conclusion

The 7100.0190.71 ceramic body fuse is a versatile and reliable protective element with numerous applications. Its solid-state design ensures that the fuse is extremely reliable and long-lasting, and its two-terminal design makes for a low-cost yet high-performance protective component. The 7100.0190.71 fuse is the perfect choice for system designers operating in the automotive, military and aviation areas who want to protect their circuits from dangerous levels of current.
