PTC (Positive Temperature Coefficient) resettable fuses are an integral part of the modern electronic circuit design, providing an effective protection against overcurrent and other hazardous conditions which can cause short-circuits and fires in electrical equipment. A PTC resettable fuse is a semiconductor device that utilizes a switch mechanism to reset the circuit when it detects an overcurrent. The PFRA.025 is a proprietary resettable fuse and it has a number of advantages over traditional fuse designs.

The PFRA.025 has a low operating current and a fast reset time, making it ideal for applications such as consumer electronics, industrial controllers, automotive and medical applications. The device can also be used in combination with other circuit protection devices, providing a highly reliable and efficient protection against shorts and other over-current conditions. In addition, the PFRA.025 is available in a variety of physical sizes, providing flexibility in selecting the appropriate fuse for the application.

The basic working principle of the PFRA.025 is based on the PTC effect. When a current above the rated threshold of the device flows through the fuse, the PTC element heats up due to the Joule heating effect. This results in an increase in the resistance of the element, causing a drop in the current and the fuse element to reset itself. The reset action is designed to be fast enough to prevent any serious damage to the equipment.

The PFRA.025 is designed to offer a high level of protection against a range of over-current conditions, including both AC and DC current. In addition, it is designed to be highly impact and vibration resistant, making it suitable for applications in demanding environments. The device is also designed with a temperature compensation that helps to reduce the possibility of resetting due to transient temperature changes.

The PFRA.025 is an ideal choice for use in a range of electronic circuit designs. It provides a fast and reliable protection against a range of over-current conditions, while offering flexibility in physical size and temperature compensation for applications in many different environments.
