PTC Resettable Fuses, such as RHEF650-2, are used as a circuit protection tool in a variety of electronic systems. A variety of electronic systems may include personal computers, communications systems, medical equipment, and industrial control systems. The RHEF650-2 is designed to protect against over-current, over-voltage, short-circuits, and AC transients.

The RHEF650-2 fuse works by using a positive temperature coefficient (PTC) element, or PTC resettable fuse. This element has current-limiting characteristics, which behave differently than a traditional fuse. A PTC resettable fuse has a higher start current than the operating current. When current levels exceed the start current, the PTC element begins to heat up, and if the current is sustained above the start current, the PTC fuse will eventually reach its opening temperature level and cause the two-pin enclosure to open. The PTC element will then cool down, resetting itself and restoring the circuit’s normal flow of electricity.

The RHEF650-2 PTC Resettable Fuse is rated for electric current between 65A and 85A, with a breakage resistance of 500mohms. It is designed with a low power loss at high currents, enabling it to effectively protect the circuit from excessive current flow. The two-pin enclosure also provides superior protection against high voltage transients. The RHEF650-2 is also designed to be used in applications where the temperature is between -30℃ and +150℃ ( - 22°F to 302°F).

The RHEF650-2 PTC Resettable Fuse has a wide range of application fields. It is used for circuit protection in personal computers, communications systems, medical equipment, industrial control systems, electrical appliances, and rechargeable battery packs. It is also used in automotive applications, such as in automobiles, motorcycles, off-road vehicles, and industrial equipment. In addition, the RHEF650-2 is used in transformer applications to protect the transformer’s feed wires against short circuits.

In summary, the RHEF650-2 PTC Resettable Fuse has a wide range of application fields, and its working principle is based on a PTC element. It is designed to protect against over-current, over-voltage, short-circuits, and AC transients. The RHEF650-2 has a current rating between 65A and 85A, and is designed with a low power loss at high currents. It is also temperature-resistant, making it suitable for use in applications ranging from -30℃ to +150℃ ( -22°F to 302°F). The RHEF650-2 is used in a variety of applications, including protecting personal computers, communications systems, medical equipment, industrial control systems, electrical appliances, and more.
