PTC Resettable Fuses offer a unique solution to the circuit protection needs in many applications – providing an electromechanical link for overcurrent protection that can be used to reset the circuit quickly after the fault condition clears. The RXEF025-AP is a popular variant of such PTC Resettable Fuses, with low profile package and high over-current rating, making it an ideal choice for many applications. This article provides an overview of the RXEF025-AP application field and working principle.

Background

PTC Resettable Fuses have been around since the early 1950s when they were used in applications such as automotive electrical systems, telecommunications, computers, and medical equipment. But since then, their use has grown significantly and they can now be found commonly used in many other applications such as consumer electronic products, industrial equipment, and more. As their use has grown, so have the varieties and performance of these devices. The RXEF025-AP PTC Resettable Fuses are a great example of this development.

Application Field

The RXEF025-AP PTC Resettable Fuses offer an ideal solution for circuit protection in a variety of applications including consumer electronics, automotive systems, motors, solar panels, and telecom equipment. Due to its low profile package and high breakdown voltage/current ratings, the RXEF025-AP is a great choice for any application requiring a low-cost, reliable, and fast-acting protection solution. Additionally, the RXEF025-AP has been tested and certified to meet IEC/EN 60335-1 safety standards for consumer electronics.

Working Principle

The RXEF025-AP PTC Resettable Fuses work by sensing an overcurrent situation and changing state (from off to on) when the maximum current rating has been exceeded. This is done with the help of a thermoset polymer element found inside the device, which acts as a link between two metal plates – one connected to the voltage source, and the other to the circuit. When the current reaches the maximum rating, the element begins to heat up and then melts and breaks the link, effectively interrupting the circuit and providing circuit protection.

Once the fault condition has cleared, the link between the two metal plates can be restored by simply pressing the reset button on the fuse. This causes the link to reform and the circuit to be “closed” again. It should be noted that if the fault condition persists, the fuse must be replaced in order to reset it.

Conclusion

The RXEF025-AP PTC Resettable Fuses are a great solution for providing reliable and fast-acting circuit protection in a variety of applications. With its low profile package and high breakdown voltage/current rating, the RXEF025-AP is an ideal choice for many applications. And with its ability to quickly reset after the fault condition has cleared, it offers a unique protection solution that is cost-effective and easy to use.
