PTC Resettable Fuses are electronic protective devices used to provide automatic protection against overcurrent. AGRF800 is a PPTC Resettable Fuses widely used in many applications. This article will discuss what the AGRF800 Resettable Fuse can be used for and basic working principle.

AGRF800 Resettable Fuse is a kind of self-restoring fuse, which can selectively stop specified overload current and protect the circuit from damage. This Type F Resettable Fuse operates by increasing its resistance with increasing current flow. When the current exceeds a preset trip level, the current will cause the fuse to reset and effectively limit the current flow. This resetting process is almost instantaneous, and it will restore the circuit automatically.

AGRF800 is used in applications that require reliable protection and automatic reset. It is suitable for overcurrent and overvoltage protection in consumer electronics and automotive applications. It can be used in a wide range of industries, including automotive, audio, lighting, and DRAM, as well as other applications including PCs, laptops, mobile phones, and power supplies. The fuse is able to withstand voltages up to 16V and currents up to 80A. It can be used in both high amperage and high voltage circuits, providing reliable protection. It also has a current interruption capability of 200A.

The working principle of the AGRF800 Resettable Fuse is simple. It is an electronic switch that is able to detect current flow and provide current protection. The fuse has two main components: the element and the contact. The element is made up of a conductive material that expands or contracts when current passes through it. The contact is also made up of a conductive material that is able to resist the expanding and contracting of the element. When the current exceeds the preset trip level, the contact is able to open the circuit, which will restrict the current flow and protect the circuit. Once the current is reduced, the element will return to its normal size and the contact will close the circuit. This will reset the circuit automatically.

AGRF800 is a reliable and cost-effective Resettable Fuses, which provide automatic current protection and reset when the current exceeds preset level. It is widely used in many applications that require reliable current protection, from automotive and audio electronics to DRAM and power supplies. The working principle is simple and straightforward; the Resettable Fuse is able to detect overcurrent and reset the circuit automatically using its two main components.
