0251012.MXL Application Field and Working Principle

The MXL series of semiconductor fuses is a new type of fuse developed and manufactured by Common Electric. The MXL features high breaking capability and excellent pulse withstanding performance. The MXL series is widely used in transportation, medical, electrical engineering, communication, home appliances, railway, and automobiles. This paper mainly introduces the application field and working principle of the 0251012.MXL.

Application Field

The 0251012.MXL is mainly used in the automotive industry for protecting power lines from overcurrents. It is designed with a 6.3mm x 32mm body size and is rated at 2.5A and 250V AC DC. It can protect vehicles from overcurrents in key systems such as the airbag system, ABS system, vehicle lighting system, and vehicle control system. The 0251012.MXL can also be used in home audio systems and electronic equipment to protect against electrical surges due to power outages, power line spikes, and transient voltages.

Working Principle

When the circuit is overloaded or short-circuited, the heat generated will rise quickly and exceed the set temperature of the 0251012. MXL. When this happens, the device will activate its internal temperature-sensitive elements which will open up the contact within the fuse and break the circuit.It is important to note that the breaking capacity of the 0251012.MXL is lower than that of a fuse with a higher breaking capacity, meaning that the 0251012.MXL will need to be replaced more frequently than a fuse with a higher breaking capacity.

The 0251012.MXL also has excellent pulse withstanding performance. This means that it is capable of withstanding sudden power surges due to power cuts, power line spikes, and transient voltages. In such a situation, the MXL fuse will activate its internal temperature-sensitive element and break the circuit at an elevated temperature, thus protecting the electronics from damage.

Conclusion

The 0251012.MXL series of semiconductor fuses are highly versatile and can be used in many applications such as automotive, home appliances, and industrial. It has excellent breaking capacity and surge withstanding performance, making it a reliable and cost-effective solution for protecting circuits from overcurrents.
