　　　　The structure of a fuse holder mainly consists of the fuse holder body, base, terminals, pins, etc. Below, we will introduce these structures separately.　　The fuse holder body is the main part of the fuse holder, which is usually made of insulating material and can fix the fuse, pins, and terminals. The shape, size, structure, and material selection of the fuse holder body will have a significant impact on the performance and reliability of the fuse holder. The fuse holder body is usually divided into various shapes such as cylindrical, square, rectangular, etc., and different shapes and sizes can be selected according to different application scenarios. In addition, the insulation material of the fuse holder body should have good insulation performance, heat resistance, and chemical corrosion resistance to ensure the safety and reliability of the fuse holder.　　The base of a fuse holder is usually made of metal material, used to fix the fuse holder body, pins, and terminals.

Application of Overcurrent Protection for Self Recovery Fuses.air conditioner fuse replacement

　　　　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.　　In daily life, there are many plug and play models of device products, and "plug and play" applications include motherboards and many peripheral devices that can be frequently connected or disconnected from computer ports. For example, devices connected to mice, keyboards, audio, networks, monitors, and USB ports may malfunction, the connecting cables may be damaged, or incorrect connections may occur.　　The application of self restoring fuses for overcurrent protection - therefore, the ability to reset after correcting incorrect connections is particularly attractive. Some of these applications use radial lead devices, while others are more suitable for surface mount devices. (Related knowledge: Application cases of self recovery fuses)

Fuse resistance.demand lighting fuse

　　　　Resistors and fuses are similar in material and construction, but their cost is reduced due to their dual function. Fuse resistors can be divided into: metal film fuse resistors, fuse type wound resistors, and fuse type cement resistors. There are several types of power: 1/4W, 1/2W, 1W, and 2W. As the power increases, the appearance size of the product will continue to increase.　　The resistance value of fuse resistance is generally small, mostly less than 1 ohm, and often acts as a sampling resistor in the circuit. At the same time, it plays a role in the occurrence of surges or other situations where large currents are generated and the circuit needs to be protected. Fusing causes the circuit to break and has a protective effect.　　At the same time, most of the fuse resistors are chip type, with relatively stable performance. They are commonly referred to as Jiebixin fuse resistors, which are also known as Jiebixin chip fuse resistors. There are two types of products: fast fuse and

How to Design Chip Fuses.normally open vs normally closed

　　　　In electronic products, chip fuses have two functions: to protect users from harm and to protect circuits from damage. These functions benefit both device users and manufacturers. Over the past decade, the demand for electronic devices serving information technology, mobile, and consumer applications has sharply increased in the market. With this rapidly growing demand, the risk of unexpected situations in electronic devices has also increased, requiring the use of overcurrent protection devices such as chip fuses to avoid risks such as electrical overload.　　Before analyzing the electrical characteristics of various chip fuses in the market, it is first necessary to understand the basic design principles behind each technology.　　Standard fuses may be based on metal wires placed inside sealed ceramic or glass tubes filled with air or sand, but chip fuses are based on completely different principles. Most chip fuses appear to be standard chip devices and are made of single or multi-l

How to choose fuses for blockage experiments

　　　　Rated current: Understanding the rated current of the equipment or motor you are testing is crucial. The rated current of the fuse should be greater than the rated current of the equipment to ensure that the fuse will disconnect the circuit and provide overload protection when the current exceeds the set threshold during the experiment.　　Short circuit protection: In the stall experiment, the equipment may generate huge currents due to overload or stall. It is important to choose fuses with lower melting current and fast melting characteristics to prevent equipment from overheating or damage.　　Freeze voltage: Select the fuse according to the voltage requirements of the equipment. The freeze voltage of the fuse should match the operating voltage of the equipment to ensure that the fuse can function properly during the experiment.　　Temperature characteristics: In the stall experiment, the equipment may generate high temperatures. Choosing fuses with appropriate temperature coefficient
