PTC Resettable Fuses are a type of global circuit protection devices that protect electrical and electronic circuits from damage due to excessive current. These devices are generally made from a Polymer based material which shows a high electrical resistance in the cold state, but when exposed to excessive current, it enters into a high temperature state. This state results into a drastic increase in electrical resistance and thus deflects all excessive current away from the circuit.

The MF-RX185 PTC Resettable Fuses are a unique form of circuit protection devices, as they use Radial-leaded technology. This technology ensures that these devices can be used in both PCBs and PC boards. The MF-RX185 feature low operating current, low temperature coefficients, small size, and high current carrying capability.

In terms of their application field, the MF-RX185 are mostly used in automobiles, telecommunications, home appliances, LED lighting, and other consumer electronic products. These fuses are also suitable for use in charger applications, power supplies, and in other power management applications. Moreover, the MF-RX185 are characterized by their fast response and fail-safe operation.

The working principle of the MF-RX185 is based on the PTC Resettable Fuse Technology, which is the core of the functionality of these devices. This technology works by allowing a certain level of current to flow through the device. When the current flowing through the device exceeds the specified level, this triggers a thermal reaction within the Polymer disc, which in turn raises the electrical resistance. This abrupt increase in the electrical resistance steers away any excessive current from the circuit, thus protecting it from damage.

The MF-RX185 PTC Resettable Fuses offer immense benefits to any type of circuit, as they not only provide protection against over-current cases, but also provide extra protection against electrical and thermal abuses. These devices are highly reliable, as their electrical characteristics remain steady and constant, even after repetitive long-term use. Therefore, the MF-RX185 are becoming increasingly popular as Circuit Protection Devices among automotive, telecommunications, LED lighting, consumer electronics, and other sectors.
