PTC resettable fuses are widely used in electronic products due to their excellent safety characteristics and low cost. B59880C0120A051 is a typical PTC resettable fuse and is widely used in many electronic products. Its application field and working principle is as follows.

As a kind of PTC resettable fuse, B59880C0120A051 is widely used in many fields such as toys, household appliances, computers, communication products, automobiles and audio-visual electronics. These products all need overcurrent protection because they use various kinds of power modules, such as transformers, switch power supplies, chip load and EMF interrupters, all of which generate electrical overcurrent. Appropriate protection is needed to avoid damage to electrical components and injuries caused by electric shock.

The working principle of B59880C0120A051 PTC resettable fuse is as follows. In normal working condition, the temperature of the chip is relatively low and the resistance is large, so the current is also relatively small, and the heat generated by the chip is very small. When an overcurrent occurs in the circuit due to an external fault, the instantaneous current is relatively large, the internal temperature of the chip rises quickly, and the resistance decreases. Due to the decrease of resistance, the current in the circuit is reduced and the overcurrent is eliminated. When the temperature returns to normal, the resistance returns to the initial normal high value and the circuit is restored to normal.

The features of B59880C0120A051 PTC resettable fuse are as follows. First, it is fast in response and has good protective performance. Second, it can be reset after the fault, that is, the fuse can be reused after the fault is removed. Third, its structure is simple and its environmental adaptability is good. Fourth, the cost is relatively low, making it widely used in various products. Fifth, it is of high reliability and its thermal performance is stable.

B59880C0120A051 PTC resettable fuse has many advantages, so it is widely used in many fields. It has not only simple and reliable characteristics, good protective performance, and high cost performance, but also can be recovered and reused after fault. Therefore, PTC resettable fuse has become the first choice for electronic product manufacturers.
