0314020.MX52LEP Application Field and Working Principle

Fuses are probably the most commonly used safety components for protecting circuit components from excessive current, providing power distribution and sensing electrical faults.

The 0314020.MX52LEP is a fuse manufactured by Littelfuse and it is specifically designed for low voltage and power applications. It features a fast-acting operation, an 85V DC voltage rating and a 0.52 amps current rating.

Application Field

The 0314020.MX52LEP is ideal for use in consumer electronics products, automotive electronics, and other high-temperature applications. It is often used to protect motors, lamps, and heaters from current overloads. This fuse can also be used as part of a system to mitigate electrical overstress (EOS) in batteries, sensors, and other sensitive components.

Working Principle

The 0314020.MX52LEP is a fast-acting fuse that consists of a metal wire or strip that has been surrounded with a non-conductive material. When the current being applied to the fuse reaches its rated value, the metal wire or strip will heat up and melt, thus breaking the circuit and preventing further current from passing through the fuse. This rapid switching time helps protect circuits from abrupt current spikes and over-amps.

The 0314020.MX52LEP has the ability to automatically reset itself after a fault condition, which makes it ideal for applications that require frequent switching on and off, such as computers or other consumer electronics. The fuse utilizes a two-piece thermoplastic construction that acts as an insulator and helps keep the temperature and current levels under control. Additionally, the 0314020.MX52LEP has a low insertion and reset voltage which makes it suitable for a wide range of voltage requirements.

Conclusion

The 0314020.MX52LEP from Littelfuse is a fast-acting, low voltage fuse, ideal for use in a variety of applications. It features an 85V DC voltage rating and a 0.52 amps current rating, and its two-piece thermoplastic construction allows it to reset itself after a fault. This fast-acting fuse is perfect for consumer electronics, automotive electronics, and other high-temperature applications, and provides protection against electrical overstresses.
