Introduction to the Classification of High Voltage Fuses.lighting fuse size

　　　　The heat emitted by high-voltage fuses through convection, conduction, and other means gradually reaches a balance with the heat generated. If the generated heat is greater than the dissipated heat, the excess heat gradually accumulates on the melt, causing the temperature of the melt to rise; When the temperature reaches or exceeds the melting point of the melt, it will cause the melt to melt, fuse, and cut off the current, playing a role in safety protection of the circuit.　　Classification of high-voltage fuses:　　1. Divided into: φ 2 φ 3 φ 4 φ 5 φ 6 and others.　　2. According to the fuse characteristics, it is divided into fast fuse type, medium delay fuse type, and delay fuse type. (It can also be divided into express and strong delay).　　3. According to the breaking capacity, it can be divided into low breaking type, high breaking type (and can also be divided into enhanced breaking type).　　4. According to safety standards (or usage regions), it can be divided into UL/cUL (North

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)

Development Trend of PTC Chip Fuse Products.ceramic fuse color code

　　　　With the continuous development of the domestic economy and the rapid rise of the domestic electronics industry, the demand for PTC chip fuse products has increased from small to large, which has greatly promoted the development of PTC chip fuses. What are the trends in the development of PTC chip fuses in terms of quality, environment, labor costs, industry, etc?　　For the application of PTC patch fuse protection in circuits, using PTC has taken the lead and is in line with the trend. The statement that it will develop and grow is currently correct. In order to adapt to modern automatic production, the demand for SMD devices is increasing, and plug-in PTCs will be limited to the application of high voltage and high current products, so SMD devices are the development trend. The current specifications are developing towards both ends of the size range and towards smaller sizes. Continuously innovate by improving voltage levels.　　Without PTC, it violates the trend and will decline. D

motor thermostat vs thermistor.Knowledge of overcurrent and overvoltage protectors

　　　　With the development of electronic technology and the upgrading of electronic products, the requirements for reliability and safety of power electronic products are increasing day by day. How many users are troubled by issues such as electrical leakage, burning of computer hosts, and explosion of mobile phones, and how many products have been delayed from being launched due to failure to pass safety testing. The diversification and complexity of problems have led to the rapid development of circuit protection components, and today's protection devices have developed into a diverse emerging field of electronic components.　　Faced with such a complex and diverse field, we have many questions. What is the development trend of protective devices? What parameters should application engineers choose appropriate protective devices based on?　　What factors should be considered in circuit design? How to handle failure analysis when encountering a faulty machine? In response to these issues, W

A good fuse has these three functions.bussmann radial fuse

　　　　The first function of a good fuse is maintenance. In general, the additional current of a fuse must be greater than the normal operating current of the circuit and have a certain overload capacity, but the margin cannot be too large.　　The second function of a good fuse is its load-bearing function. This is commonly referred to as the ability to withstand pulses. During the use of fuses, there is a greater chance of normal current fluctuations or instantaneous pulses than fault overcurrent, which is particularly important for the use of fuses.　　The third function of a good fuse is its safety function. A high-quality and reliable fuse should ensure safety before, during, and after its operation, that is, safely conducting and safely fusing. In summary, appropriate fusing characteristics and additional current; Satisfactory and reasonable melting heat energy value; Proper breaking ability, additional voltage, and safety certification are necessary conditions to ensure the main functio
