PTC Resettable Fuses (PRF) is an electronic device that serves to rapidly detect and protect against overcurrent, undervoltage or thermal overload events to ensure that the electronic system components involved in a power supply are within the desired operating conditions. According to its structure and characteristics, it is classified into different types, such as smps ptc fuses, ge ptc fuses, relay type ptc fuses, etc. Among them, YPCL0045N is one type which finds its special applications in various fields. Moreover, its working principle is also about how it offers protection to different electronic systems.

YPCL0045N, with its Japanese NMB brand, is a resettable fuse with single pole, double through type (SPDT) construction. As a resettable fuse, it can be the automatic protection element of the equipment and becomes self-restoration after power recycling or expiration of the over-current and over-temperature caused by power device abnormality. The rated current of YPCL0045N is 45A, and its rated voltage is 250V AC/DC. Due to its excellent performance and reliability, it has been extensively found in many applications, including desktop computers, car audio, LED lighting, power supplies, power adapters, DC motors, solar LED lights, industrial automation control systems, etc., to protect them from potential fire or electric shock hazards.

On the other hand, the working principle of YPCL0045N is also a very important issue in its application field. The device works with the principle of a PTC thermistor, which has self-healing and overcurrent protection functions. When a current passing through it is beyond its limit, the thermistor will heat up and increase the resistance in a short time. As a result, the current can be limited, thus realizing the protection of the power devices. When the overcurrent situation is eliminated, the thermistor will cool down and the resistance returns to the lower level, enabling the electrical circuit to ensure the current flow again.

What makes YPCL0045N so useful is its wide range of application and its working principle. In addition, the advantages of YPCL0045N also attract many people to use it as overcurrent protection device: one is that it has high breaking capacity and fast response speed; the other is that it has ability to operate repeatedly and no spark discharge. Besides, understanding its working principle will also help users a lot when they\'re using YPCL0045N in their applications.

In conclusion, YPCL0045N belongs to the family of PTC Resettable Fuses which has a variety of applications and a convenient working principle. Its rated current is 45A and the rated voltage is 250V AC/DC which makes it an ideal device for its application. Moreover, its features of high breaking capacity, fast response speed and repeated resetting have further widened its application areas, such as desktop computers, car audio, LED lighting, power supplies, power adapters, etc. Therefore, YPCL0045N can be used as an effective protection device for many electronic systems.
