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.
Also, the fuses used must meet the specifications, as incorrect fuses can damage the horn. Installing circuit breakers is also a solution; However, before they are disconnected, noise will be generated when they begin to disconnect.
So, a better choice is a Self Recovery Fuse element. When the Self Recovery Fuse is in the disconnected state (in a high resistance state), it acts as a soft switch and automatically returns to the low resistance path state when the fault is eliminated.

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.
What is A Self Recovery Fuse
Self recovery fuse is an overcurrent electronic protection component that uses a polymer organic polymer under high pressure, high temperature, and sulfurization reaction conditions.After mixing with conductive particle materials, it is processed through a special process. Habitually applying PPTC (Polymer Positive Temperature).
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.

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?
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.
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.
What are the Standard Requirements for Self Restory Fuse Technology?
Self recovery fuse is a type of overcurrent electronic protection component, which is made by mixing conductive particle materials with polymer organic polymers under high pressure, high temperature, and vulcanization reaction conditions, and processed through special processes. What are the standard requirements for self restoring fuse technology? 1. The rated zero power resistance PPTC thermistor should be packaged in different levels according to the zero power resistance, and the resistance range should be indicated on the outer packaging.
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.
