PFUF.050.2 Circuit Protection

PTC Resettable Fuses are typically used to protect electronics from damage due to overcurrents, and the PFUF.050.2 is no exception. This specific type of fuse is designed for sensitive and mission-critical applications, where higher current ratings are required. It is also recommended for high-performance, high-temperature applications.

The PFUF.050.2 is a polymeric-film-based PTC Resettable Fuse designed to provide both short-circuit and over-current protection. Its construction is based on a polymeric film, or PTC, which is encased within a tube, creates a resistance to current flow. The resistance is designed to increase as the current flows through the PTC, resulting in an increase in temperature. When the temperature reaches a certain point, the PTC will open up and limit the current flow. When the current is reduced, the temperature will decrease and the PTC will reset itself. This feature makes the PFUF.050.2 an ideal choice for applications that require reliable over-current protection.

The PFUF.050.2 offers a wide range of features and benefits. Due to its robust construction, it is capable of withstanding temperatures up to 125°C without damage. Additionally, the fuse is shock- and vibration-resistant, making it suitable for extreme environments. It is also fully RoHS compliant and features an extremely low resistance value, which ensures that it will limit current flow if an over-current event occurs.

The PFUF.050.2 is suitable for a wide variety of applications, ranging from consumer electronics and home appliances to industrial and automotive systems. In most cases, the fuse is installed between the power source and the protected device. This allows the PTC to open up in the event of an over-current, protecting the device from damage. Additionally, the low resistance value allows the fuse to open quickly, minimizing the risk of damage.

In conclusion, the PFUF.050.2 is an ideal choice for reliable over-current protection in sensitive and mission-critical applications. Thanks to its robust construction and low resistance value, it is capable of withstanding temperatures up to 125°C and providing fast, effective protection against over-current events. Additionally, it is suitable for a wide range of applications, from consumer electronics to automotive and industrial systems, making it an excellent all-around choice.
