PTC resettable fuses, or PPTC (Polymeric Positive Temperature Coefficient) resettable fuses, are a really handy device. They offer a compact and cost-effective alternative to traditional circuit protection solutions. And one of the most popular resettable fuses available in the market today is the PFRX.135. So, let\'s take a deeper look at the PFRX.135 and its applications as well as its working principle.

PFRX.135 is an advanced and reliable PTC resettable fuse that offers reliable overcurrent protection and circuit resetting. This fuse is rated for up to 6A and can handle up to 135°C operation temperature. It comes in a small yet compact design, making it ideal for space-constrained applications. The PFRX.135 offers a wide range of applications, including protection of consumer-electronics, automotive, industrial, and medical devices. For instance, it can be used to protect digital circuit boards, PCB lines, and other electrical and electronic components. It also offers protection against accidental overloads, miswiring, and short-circuits.

As for its working principle, the PFRX.135 works by taking advantage of a heat-sensitive device. This "device" is basically a PTC element that begins to heat up when the current passes through it, causing a chemical reaction. The chemical reaction generates a heat that creates an increased resistance to further current flow. As the current continues to flow, the PTC element will heat up to a point where the resistance becomes so high that the circuit shuts off automatically, like a regular fuse would.

When the overcurrent is removed, the PTC element cools down and the current begins to flow again. Unlike a traditional fuse, however, the PTC element can be reset manually by simply toggling the circuit breaker. This makes the PFRX.135 the ideal choice for applications that require protection against transient overcurrent conditions, without the need for replacing the fuse after each fault.

The PFRX.135 provides a reliable and cost-effective solution for overcurrent protection across a wide range of applications. From consumer-electronics to automotive and industrial equipment, the PFRX.135 is well-suited for many different applications. What\'s more, its manual resetting capabilities make it an ideal solution for reliable circuit protection against transient overcurrent conditions. All in all, the PFRX.135 is definitely one of the most popular resettable fuses available today.
