PTC Resettable Fuses, also known as PolySwitch, are a type of fuse used in application fields that requires self-resetting protection. The RLD60P090XF is one of the most popular PTC fuses, widely used in electric and electronic products. It can be applied as a component to protect against overcurrent protection, overload protection, short circuit protection, over voltage protection and thermal protection.

The working principle of the RLD60P090XF is as follows. When the current flowing through the device exceeds a certain maximum threshold, the resistance of the RLD60P090XF increases rapidly. This in turn conducts heat, which causes the temperature of the fuse to rise quickly. As the temperature increases, the fuse must quickly be able to open up, blocking the current. This is known as the “auto-reset” feature, making it an ideal solution for applications that require thermal and short circuit protection.

In addition, the RLD60P090XF can be used in many applications such as consumer electronics, automotive, power supply, telecommunications, and industrial equipment. It is also a cost-effective alternative to traditional fuses, as it eliminates the need for replacement or reset after the fuse has tripped. This feature makes the fuse suitable for applications that require frequent trips, such as those caused by power surges.

The RLD60P090XF provides superior temperature stability and long-term electrical insulation. It can be connected to a circuit in one of two ways. The first is a simple three-lead connection, while the second is a more complex five-lead connection. The three-lead connection involves connecting the anode and cathode leads to the respective outputs, while the five-lead connection involves connecting the anode and cathode leads to the respective inputs/outputs.

In summary, the RLD60P090XF is a highly versatile PTC resettable fuse that can be used in a wide range of applications. Its auto-reset feature and good temperature stability enable it to provide excellent protection against both current overloads and overtemperature damage. Furthermore, its cost-effective solution makes it an ideal solution for applications that require frequent trips or where overcurrent protection is necessary.
