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? Regarding the selection of self recovery fuses, Baodian Tong will explain to you:
Step 1: Determine the standard working current, maximum working voltage, maximum fault current, maximum working environment temperature, action time, and other parameters for the normal operation of the protected circuit;
Step 2: Determine whether it is a plug-in PTC or a patch PTC based on the characteristics of the protected circuit or product;
Step 3: Select PTC products with a withstand voltage level greater than or equal to the maximum working voltage based on the maximum working voltage
Step 4: Select the appropriate product specifications based on the maximum ambient temperature and standard operating current in the circuit, and compare them with the PTC temperature reduction rate;
Step 5: Confirm whether the selected product meets the required action protection time based on the action time curve of the PTC model;
In the actual process, many protected circuits require extremely complex requirements, and the specific model selection of PTC still needs to be determined based on experimental testing. I would like to learn more about the application of self restoring fuses, maintaining power supply, and interesting and informative technology. Be the first to know.

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 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.
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.
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.
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.
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.
Self Recovery Fuse Specification, Must Understand
Each type of circuit protection component has specifications, and self recovery fuses are no exception. So, what do you think when holding a self-healing fuse specification book? To put it bluntly, when reading the specifications, the main focus is on the parameters and the meanings they represent.
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.
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.
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.
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.
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.
