PTC Resettable Fuses, also known as polyfuses, are fuses designed to automatically react to overcurrent conditions and reset after the fault is corrected. The commonly used PTC type is a thermistor with a positive temperature coefficient of resistance. In general, PTC fuses are self-restoring electronic components used to protect against the current or surge overloading of circuits.RTEF190-2 fuse is a type of PTC Resettable Fuses. Its thermal fuse is designed for protecting electronic components from power surges occurring in house lighting applications and in automotive and commercial circuits. This fuse has a rated current of 2A and a trip current of 55A and can be used for any device rated up to 2A. RTEF190-2 is a two-lead device. It has a low profile, uni-body design, and clip in mounting, which makes it ideal for use in the most demanding automotive applications. It also features environmental protection against dust and water.The working principle of RTEF190-2 is based on the PTC effect. When the current passes through the thermal fuse, the PTC crystal generates heat due to resistance. As the current increases, the temperature of the crystal increases, and when it reaches a certain level (its trip temperature), the thermal fuse will open the circuit. When the current is reduced, the temperature of the crystal will decrease and the thermal fuse will return to its low-resistance state and restore the circuit.RTEF190-2 fuse has a broad range of applications. It is often used in automotive circuits for the protection of alternators, sensors, and other electronics from overload. In home lighting applications, the RTEF190-2 fuse can be used for the protection of house lights from overload. It can also be used in commercial circuits and industrial circuits for overload protection.Overall, RTEF190-2 fuse is an effective way of protecting electronics and electrical circuits from overloading. It has a low profile, uni-body design, and clip in mounting making it suitable for a wide variety of applications. The working principle is based on the PTC effect, where the thermal fuse opens the circuit when the current reaches a certain level, and will restore the circuit when the current is reduced.The specific data is subject to PDF, and the above content is for reference
