Principle of Resettable Current Fuses

　　　　Resettable current fuses offer a unique solution for protecting electrical circuits while providing the convenience of being reusable. Here's how they work.　　Resettable current fuses typically use a polymer-based material that changes its electrical resistance in response to an increase in current. When the current exceeds a certain threshold, the polymer material heats up and changes its state, increasing its resistance and limiting the current flow.　　Once the overcurrent condition is removed, the polymer material cools down and returns to its original low resistance state, allowing the circuit to resume normal operation. This resettable feature makes these fuses highly convenient as they do not need to be replaced like traditional fuses after each overcurrent event.　　The principle of operation of resettable current fuses is based on a combination of thermal and electrical properties of the polymer material. The material is designed to have a specific temperature coefficient of re

A Brief Discussion on the Future Development of Recoverable Fuses

　　　　Recoverable fuses are circuit protection components that many electronic industries consider first. They are widely used in transformers, security equipment, lighting fixtures, ballasts, instruments, telephone lines, and other fields, benefiting from the development of new technologies such as digital technology, communication technology, and new energy, In the first ten years, the market sales quantity and sales amount of circuit protection components and recoverable fuses showed a steady growth trend.　　With the continuous transfer of industrial chains in developed countries, China has now become an important production base for global electronic products. At the same time, with the rapid development of China's economy, the demand for circuit protection components in downstream markets is becoming increasingly strong, and in the future, the process requirements for circuit protection components to recover fuses will become more stringent.　　The development trend of the recoverable

　　　　1. When operating at a normal operating current of 25 ℃, the current rating of the fuse should usually be reduced by 25% to avoid harmful blowing. Most traditional fuses use materials with lower melting temperatures. Therefore, this type of fuse is relatively sensitive to changes in ambient temperature. For example, a fuse with a current rating of 10A is usually not recommended to operate at an ambient temperature of 25 ℃ and a current greater than 7.5A.　　2. The voltage rating of the fuse must be equal to or greater than the effective circuit voltage. The general standard voltage rating series are 32V, 125V, 250V, and 600V.　　3. The resistance of a resistor fuse is not important in the entire circuit. Since the resistance of a fuse with an amperage less than 1 is only a few ohms, this problem should be considered when using a fuse in a low-voltage circuit. Most fuses are made of materials with a positive temperature coefficient, so there are two types of resistors: cold resistance a

motorcycle blown fuse symptoms.The Price Trend and Future of Fuses

　　　　We know that in recent years, especially since 2016, domestic factories have increased their machinery and equipment on a large scale, especially the increase in square and SMD fuse automata, which has led to a continuous decline in these products in China. Especially, the price of square fuses has become transparent to the point where customers do not want to negotiate. There are actually several reasons for this situation:　　1: It is the continuous decline of the Chinese yuan, the constant hovering of the US dollar exchange rate, and the depreciation of the Chinese yuan　　2: There are too many homogeneous products, and in order to win more orders, we can only continuously compress profit margins, which is a common problem in the domestic manufacturing industry　　3: After the tax increase in the United States, many orders have been sharply reduced, especially the significant impact of large customer revenue, further forcing fuse factories to compress profit margins and dilute operati

blower motor fuse keeps blowing.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:　　I hold: Maintain current　　I trip: The maximum action time under the specified current;　　V max: Maximum voltage that can be withstood　　I max: Maximum current that can be withstood　　P d: Stable power consumption in high resistance state　　R: Zero power resistance measured at a certain temperature　　R 1max: The maximum resistance value measured at room temperature after one hour of action or soldering back　　Environmental temperature: The temperature of the still air around PTC　　Maximum working environment temperature: The highest ambient temperature for PTC safe operation
