PTC (positive temperature coefficient) resettable fuses serve as current-limiting devices that are used to protect circuits from overloads or short-circuiting. The RHE400 is a type of PTC resettable fuse and it is specifically designed for use in applications such as computers and peripheral equipment, digital cameras, LCD TVs, and other types of digital consumer equipment. In this article, we will discuss the application field and working principle of the RHE400.

Before discussing the application field and working principle of the RHE400, it is important to note that this type of PTC resettable fuse is designed specifically for low-voltage, low-current applications. The RHE400 is suited for use in equipment that requires low power consumption such as desktop computers, laptop computers, video game consoles, and other digital consumer equipment.

The application field of the RHE400 is quite broad. It can be used in various applications such as line-yielding fuse, surge protection, and protection for electronic circuits. The RHE400 is particularly suited for use in applications where a high level of protection against short-circuiting and overloads is required. It is also ideal for applications where a wide operating temperature range and accurate current measurement are necessary.

The working principle of the RHE400 is fairly simple. The device is designed to cut off or disconnect power when a predetermined overcurrent is detected. It does this by detecting a rapid increase in electric current or by sensing that the temperature of the RHE400\'s element is getting too high. When either of these conditions is detected, the RHE400 will open up, effectively disconnecting the circuit and cutting off the power. This process is repeated until the fault or overload is corrected.

The RHE400 also has several other features that make it well-suited for use in a wide range of applications. For example, the PTC element used in the device is temperature-sensitive and will automatically reset after the fault or overload has been corrected. Additionally, the RHE400 includes a mechanism which allows it to "self-heal" after a fault has been corrected, meaning it can potentially reduce downtime and harmonics significantly.

Overall, the RHE400 is an excellent choice for low-voltage, low-current applications that require a high level of protection against short-circuiting and overloads. It is highly reliable, efficient, and cost-effective, making it an ideal option for many consumer electronics applications. Therefore, the RHE400 is an ideal choice for applications where a wide operating temperature range and accurate current measurement are necessary.
