PTC resettable fuses are the top choices for device protection from electronic overcurrents. They are mounted onto devices and circuit boards to help prevent damages from surges, overheating and short circuits. The LVR012S-2 is one of the most popular PTC resettable fuses. It offers superior protection and reliability over other models. In this article, the application fields and working principle of the LVR012S-2 will be discussed.

Application fields of LVR012S-2

The LVR012S-2 PTC resettable fuse has a wide range of applications in both consumer and industrial products. It can be used for corded and cordless power tools, portable medical devices, white goods, audio-video equipment, dishwashers, and ventilation systems. It is also suitable for automotive electronics and battery packs applications. It is designed to protect motor and compressor circuits against short circuits, overload, and over current.

Working principle of LVR012S-2

The LVR012S-2 PTC resettable fuse works based on a self-reset principle. It provides reliable protection against short circuit and overload from overcurrents. When an overcurrent occurs, the fuse incorporates a parallel connected PTC thermistor, or Positive Temperature Coefficient thermistor, which opposes current flow and generates heat. This resistive heat causes the fuse\'s resistance to increase and triggers the self-reset process. As the current decreases, the fuse\'s resistance returns to its original state and the device restores its electrical connection.

For increased safety, the LVR012S-2 resettable fuse is equipped with a ceramic housing and two metallic layers which enable better thermal conductivity for faster cooldown and faster re-stabilization of the fuse. This maximizes the protection of the device and helps improve the life span of the fuse. It is also designed with a low profile which enables easy installation and integration into confined spaces.

Conclusion

The LVR012S-2 PTC resettable fuse is a versatile device that offers protection against short circuits, overloads, and overcurrents. It is suitable for a wide range of applications and is designed with a low profile for easy integration and installation. The fuse works based on a self-reset principle and is equipped with a ceramic housing and two metallic layers for better thermal conductivity and faster cooldown. All these features make the LVR012S-2 an ideal solution for device protection.
