PTC Resettable Fuses are a type of electrical protection component that use a polymeric PTC (Positive Temperature Coefficient) device as the key element. The PTC resettable fuse has the advantages of small size, fast response time, repeatable response, and automatic recovery. The RUE135 application field and working principle are as follows.

RUE135 is a PTC resettable polymeric fuse that is developed by the company for use in batteries and DC/DC converter circuits. The device, which is available in a small surface-mount package, provides a very fast response time to overcurrents of up to 8A. The device also has excellent overcurrent protection characteristics.

The RUE135s working principle is based on the property of PTC which is the ability to change its electrical resistance when heated. Specifically, the PTC device will increase its electrical resistance when exposed to an overcurrent, thus limiting the current. When the overcurrent is removed, the PTC device will cool down and return to its normal low-resistance state. This allows it to reset and automatically recover from the overcurrent event.

RUE135 has applications in various fields. In terms of low voltage batteries application, RUE135 can be used in portable electronic devices, such as mobile phones, digital cameras, and other devices that require a constant voltage level and overcurrent protection. In terms of consumer anti-surge application, RUE135 can be used to protect circuit boards from overvoltage surges. In terms of DC/DC converter circuit protection, RUE135 can provide proper protection for the power source and other circuit components.

RUE135 provides an effective solution for overcurrent protection, and its small size and fast response time make it an attractive choice for a range of applications. The PTC resettable fuse allows the device to reset itself automatically, ensuring that the device is reliable and will continue to provide protection in the event of an overcurrent.
