PTC(Positive Temperature Coefficient) resettable fuses, is a kind of automatic protection products, also known as polymeric positive temperature coefficient resettable fuses. Its structure is made up of a PTC thermistor and a resin shell. PTC resettable fuses have the advantages of low cost, high precision, good overload protection performance, fast reaction speed, long service life and so on. They are widely used in the fields of communications, power, railway transportation, automotive electronics, computer peripherals and some electronic products. The MF-RX135/72-AP is an excellent example of a PTC resettable fuse.

The MF-RX135/72-AP is mainly used in the fields of telecommunication, computer network, audio and video equipment, and automobile electronics. It can be used as a protection element for current, over-voltage, short circuit and other occasions, providing accurate protection against overload and over current. It has a good temperature coefficient characteristics and a large spike current response time. The main advantage of the MF-RX135/72-AP is that it can be easily reset, allowing it to be used multiple times without sacrificing performance. In addition, its start current and trip current can be adjusted according to the requirements of each application.

The working principle of the MF-RX135/72-AP is based on the PTC thermistor. The PTC thermistor is a kind of electrical component with positive resistance-temperature coefficient. When the current passes through the PTC thermistor, the resistivity increases with the increase of the temperature. When the current reaches the preset limit, the temperature increases sharply, and the resistivity increases sharply, forming a self-resetting protection function. The process of self-resetting is completed in a few milliseconds.

In addition, the MF-RX135/72-AP also has good electrostatic protection characteristics. It can provide reliable protection for the system against static electricity, lightning, sparks, etc., thus ensuring the stable operation of the system. It also has a good temperature tolerance and can work reliably within the working temperature range of -25℃~125℃.

The MF-RX135/72-AP is an excellent solution for a variety of electronic protection applications. It is small in size, has high reliability, fast protection response, and can be easily reset, providing a reliable and cost-effective solution for overload and overcurrent protection.
