PTC resettable fuses are widely used in the industries of consumer, automotive, medical, audio, instrumentation and communication as they can protect electronic devices from surges and outbursts. RKEF065 is a new type of PTC resettable fuse with unique features. This article will go in-depth into the application field and working principle of RKEF065.

RKEF065 PTC resettable fuses are mainly used in communication devices, such as Ethernet, SCSI bus, USB, and other circuit board applications. It is especially suitable for these occasions due to its low voltage drop, fast reaction time and reliable protection. This product is also heavily used as a surge protector in industrial audio and instrumentation equipment, since its lightning protection ability can help the equipment to maintain their normal working state even under power system glitches.

In addition to its wide application among different industries, the working principle of RKEF065 should always be kept in mind. This product is a Poly-Therm-Cut (PTC) resettable fuse, also known as a polymeric positive temperature coefficient device. It is made of a positive temperature coefficient (PTC) material, which provides circuit protection from excessive current conditions. Once the current exceeds the rated melting point, the PTC thermistor will heat up due to its positive temperature coefficient and restrict the current flow.

When the current returns to normal, the PTC thermistor will cool down and reset to its original state, eventually allowing the circuit to resume its normal activity. This feature of RKEF065 makes it an ideal choice for surge protection and overcurrent protection due to its superior reset capability.

To summarize, RKEF065 PTC resettable fuses are widely utilized in communication devices, industrial audio and instrumentation equipment and other circuit board applications due to its reliable protection and reset capability. RKEF065 is a unique type of PTC resettable fuse whose working principle relies on the positive temperature coefficient feature of its PTC thermistor.
