PTC Resettable Fuses are used in a variety of applications, including automotive, industrial, consumer, commercial and medical products. They are designed to open on overcurrent conditions, protect against electrical overloads, provide short-circuit protection, and reset when the current conditions return to normal. The FEMTOASMDC008F-2 is a PTC Resettable Fuse that is specifically designed to provide short-circuit protection for a variety of products.

The FEMTOASMDC008F-2 is a small chip size fuse that provides resistance to overcurrent. The FEMTOASMDC008F-2 has a typical resistance of 0.15 ohms when the current flows through it. The resistance increases sharply with increasing current. The fuse quickly opens when the current reaches a certain rated value, and will remain open until the current decreases below a fixed re-triggering current.

In terms of application fields, the FEMTOASMDC008F-2 can be used in a variety of applications. It is suitable for applications where short-circuit protection is required for high-performance power systems, such as batteries, inverters, and DC/DC converters. It can also be used in automotive components, consumer products, medical equipment, and industrial products.

In terms of working principle, the FEMTOASMDC008F-2 operates by using a two-terminal, non-inductive, non-linear reactive element called a polymeric positive temperature coefficient (PPTC). The PPTC consists of a material that changes from a highly conductive state to an almost non-conductive state when the current flowing though it increases to a certain level. When this happens, the PPTC will switch to the high resistance state, which will cause the fuse to open and provide protection against overload or short-circuit conditions.

Once the over-current condition has been cleared, the PPTC will switch back to the low-resistance state, and the FEMTOASMDC008F-2 will reset itself. The fuse can be reset multiple times, as long as the current remains below the rated current.

The FEMTOASMDC008F-2 is a reliable and cost-effective solution for providing short-circuit protection for a variety of applications. It is a highly reliable PTC Resettable Fuse that is designed to provide protection from short-circuits, overloads, and other over-current conditions.
