PTC Resettable Fuses play an important role in the circuit protection field. They are commonly used in applications where traditional fuses fail to provide protection as effectively. The LVR100S is one such type of PTC resettable fuse, and it has a number of useful features. This article will explore the application field and working principle of the LVR100S.

The LVR100S is primarily used in low voltage, low current applications. It is most commonly found in consumer electronics and computer-related equipment. These fuses are capable of protecting a circuity from being damaged by overcurrent, overvoltage, short-circuits and other faults. Additionally, they provide excellent protection from arcing and sparking at low voltage and current levels.

In terms of working principle, the LVR100S operates in one of two modes: the overvoltage/ overcurrent mode and the short-circuit mode. In the overvoltage/overcurrent mode, the fuse will activate if the voltage or current level exceeds its rated value. This will result in the fuse opening and breaking the circuit. The fuse will then reset itself once the fault is removed and the voltage and current levels return to normal. In the short-circuit mode, the fuse will activate if the circuit has an abnormally low resistance. This will result in the fuse opening and breaking the circuit, again resetting itself once the fault is removed and the resistance returns to a normal level.

To further increase the safety of the circuit, the LVR100S also features a temperature gain circuit. This will activate a thermal switch at a certain temperature to further enhance the current/voltage protection provided by the fuse. Additionally, the fuse is designed with a reverse current blocking capability to protect components connected to the circuit from being damaged in cases of reverse current.

Moreover, the LVR100S features a dual-function terminal block for connecting load wires. This has the advantage of providing a secure connection and preventing accidental disconnection. Additionally, the fuse’s capacitance is specifically designed to withstand harsh environments such as extreme temperatures and vibration.

The LVR100S is a highly reliable and cost-effective PTC Resettable Fuse. It is well-suited to applications where a low voltage, low current circuit needs to be protected from overvoltage, overcurrent, and short-circuits. The fuse’s internal temperature gain circuit, reverse current blocking capability, and terminal block further increase its protection capabilities. Thanks to its excellent protection, reliability, and cost-effectiveness, the LVR100S has become a popular choice for manufacturers and designers everywhere.
