With the vigorous development of digital information technology, automobiles have also entered the era of intelligence and multimedia, which has accordingly promoted the innovation and integration of automotive electronics. Automotive electronics is an electronic control system composed of electronic components such as sensors, microprocessors, actuators, and their parts. It should be known that the working environment of automotive electronics is extremely harsh and demanding. When any device is connected to a 12V power supply, its working voltage must be maintained in the range of 9V-16V. At the same time, it must always respond to load dump dumps and battery reactions. Problems such as direction, peak signal, cold start, noise, etc. Therefore, the role of circuit protection components in automotive electronics cannot be ignored. Next, Dongwo Electronics, a professional manufacturer of circuit protection components, shared the topic: self-recovery fuses, protection applications in automotive electronics.
