PTC Resettable Fuses have become increasingly integrated into today’s higher power electronics. They are used as a safeguard to protect integrated circuits, fans, motors, and other components from overheating or current surges. The MF-SM013/250V-2 is a PTC Resettable Fuse with applications and properties that make it suitable for a wide variety of applications.

There are two types of PTC Resettable Fuses – conventional and intelligent. Conventional solid state fuses are designed to protect circuits from high current surges that could overwhelm and short out the circuit. Intelligent fuses contain sophisticated integrated circuits that can monitor and regulate the current flowing through circuits, thereby preventing damaged caused by high electrical current.

The MF-SM013/250V-2 is a conventional series type PTC Resettable Fuse. It has a trip current rating of 30A, a holding current rating of 23A, and a maximum voltage rating of 250V. This type of fuse offers excellent electrical characteristics, such as rapid response and high inrush current capability. It can withstand high peak currents and short circuit currents, which make it an ideal choice for protecting electrical circuits.

The main application field for the MF-SM013/250V-2 is power supply and charger applications, and it is ideal for any electronic device requiring a reliable, resettable overcurrent protection circuit. It is also suitable for automotive applications, machine tools and other equipment with high power requirements. The MF-SM013/250V-2 provides an easy, cost-effective way to protect against overcurrents and short circuits.

The working principle of the MF-SM013/250V-2 is relatively simple. It is designed to detect and interrupt the current flow when the current running through it exceeds the preset trip current value. When this occurs, it will switch to an open circuit state, interrupting the current flow and protecting the circuit from potential damage. The fuse will remain open until the current drops back below the holding current value for a specified period of time. Once the current is below this value, the fuse will automatically reset and allow current to flow through it again.

The MF-SM013/250V-2 is a reliable, cost-effective solution to overcurrent and short circuit protection, and is ideal for a wide range of applications. It provides an easy, convenient way to protect important circuits and components from potential damage caused by overcurrents and short circuits.
