Briefly describe the application field and protective effect of self recovery fuses in automobiles
With the continuous development of China's economy, cars have become an essential means of transportation for people's travel. With the increasing number of urban cars, the application of the fuse industry in the automotive field is also becoming more and more widespread. Currently, 40% of cars use various electronic devices. So where do we need to provide over temperature/over voltage/over current protection, and what devices should be used for correct protection? This issue requires us to have a deeper understanding.
The main applications of self restoring fuses in automotive circuit protection devices include small and medium-sized car motors, wiring harness junction boxes, automotive circuits, and automotive consumer electronics. Automotive electronic protection includes battery charging circuits, cigarette lighter interfaces, PCB wiring, and IEEE1394 networks; In car consumer electronics include in car audio, DVD, TV, etc.
self recovery fuses are used in automobiles to prevent dangerous situations such as circuit overcurrent/overheating caused by various faults, such as motor blockage in controlling doors, windows, skylights, and seats, short circuits caused by wire harness wear, secondary short circuits in transformer coils, reverse connections in battery boxes, and abuse of cigarette lighters. Overvoltage caused by car starting, braking, and battery box plugging can be protected by overvoltage devices. The self restoring fuse should be able to withstand various overvoltage impacts inside the vehicle.

Explanation of Parameters in the PPTC Specification for Self Healing Fuses
This is very simple. As long as you know the meaning represented by the parameters in the specification book, you can clearly and quickly view the PTC specification book for self recovery fuses.
Self Recovery Performance and Working Process of Self Recovery Fuses
Traditional fuses are installed in circuits. When an overcurrent occurs due to a fault or abnormality in the circuit, the fuse itself melts to cut off the current and protect the circuit. However, due to the fact that traditional fuses can only protect once and need to be replaced if burned out, some products still cannot resume operation after troubleshooting or abnormal overcurrent disappears. As a new type of overcurrent protection device, the self-recovery fuse has the function of automatic recovery, which can meet the performance requirements of similar applications.
Principle and Characteristics of Self Recovering Fuses
As a new type of overcurrent protection component, self recovering fuses have the advantages of self recovery, fast response speed, and small size, and have broad application prospects in electronic devices and circuits.
The Application of Self Recovery Fuses in RS485 Interface
As is well known, the interface of intelligent instruments was originally RS232, which can achieve point-to-point communication, but this method cannot achieve networking function. The subsequent RS485 resolved this issue. So the current RS485 interface is quite popular among intelligent instruments. Today, the editor will explain the application of self recovery fuses in the RS485 interface.
The Selection of Miniature Fuses
Miniature fuses are primarily used in digital cameras, laptops, mobile phones, and other electronic products. From traditional glass tube fuses to miniature fuses, the selection focus varies slightly due to differences in product technology. The selection of miniature fuses involves the following elements.
Self Healing Fuses, a New Type of Overcurrent Protection Component
Self recovery fuse is a new type of overcurrent protection component with unique performance and wide application prospects.
Application of Overcurrent Protection for Self Recovery Fuses
The overcurrent protection application of self recovery fuses - There are two optional types of self recovery fuse materials: radial lead packaging and surface mount. The function of self restoring fuses is suitable for various design applications.
Guidelines for Selecting Self Restoring Fuses and Disposable Fuses
How to choose between traditional disposable fuses and self restoring fuses, as there are significant differences between these two components? Next, we will provide a detailed introduction to the advantages of these two types of fuses, making it easier for everyone to better understand these two products and choose the fuse they need.
Experience in Selecting Self Recovering Fuses
Do you have any good experience to share in selecting self recovering fuses? Self recovery fuse is an overcurrent electronic protection component, which is made of high molecular weight organic polymers under high voltage, high temperature, and sulfurization reaction conditions, mixed with conductive particle materials, and processed through special processes.
The Application of Self Recovery Fuses in the Horn System
The protection requirements for the horn system are relatively strict. Ordinary fuses only provide one-time protection in the horn, increasing the repair rate of the product； In addition, additional fuse boxes and wires increase the manufacturer‘s costs.
The Protection Application of Self Recovery Fuses in Sweepers
With the rapid development of modern technology, a large number of products can only be integrated into our daily lives, and the broom is one of them. As a smart home product, floor sweepers are not uncommon in first tier cities in China. The working principle of a floor sweeper is not too difficult to understand, mainly relying on the drive of internal small motors to provide power. Due to unstable voltage or jamming during operation, the motor may encounter problems such as rotor blockage, overload, or even burning out.
Self Recovery Fuse for Overheat Protection in Circuits
Self restoring fuses can respond to temperature increases caused by external heat and internal current, and establish thermal connections with high-voltage equipment to provide overheating protection. Establishing this thermal connection can be achieved by arranging these devices in contact with or near high-voltage equipment.
The Difference between Self Recovery Fuse and Blown Fuse
What is the difference between a self restoring fuse and a blown fuse? It is inevitable to have a clear understanding of the functions, parameters, and differences between them. So, let‘s experience the charm of self recovery fuses and blown fuses.
Selection Guide of Self Recovery Fuse
Self recovery fuses are widely used for overcurrent protection of power lines, communication lines, and I/O ports in electronic products such as communication, security, industrial, automotive, and consumer products. So, in actual circuit protection, how should we choose the appropriate model of self recovery fuse to achieve the best protection effect?
Self Recovery Fuse on Mobile Power PCB Board
The mobile power supply consists of overcurrent protection devices, batteries, and control charging and discharging circuits. The previous charging and discharging circuits used ICs for overcurrent protection, which were complex, had high failure rates, and high costs. Some users returned or repaired the circuit, and the manufacturer was fined and claimed compensation, which caused great trouble for manufacturers and designers. The above problems must be solved in order to promote their application.
