　　How to choose the appropriate fuse

　　Choosing the appropriate fuse requires consideration of multiple factors, including the operating voltage, operating current, load type, and environmental conditions of the circuit. Here are some key steps when choosing a fuse:

　　1. Determine the maximum current of the circuit: This is the basis for selecting the rated current of the fuse. The rated current of the fuse should be slightly greater than the maximum operating current of the circuit to avoid frequent melting.

　　2. Consider the voltage of the circuit: The rated voltage of the fuse should be greater than or equal to the operating voltage of the circuit to ensure its normal operation.

　　3. Choose the appropriate type: Select fuses of different types and specifications according to the specific needs of the circuit. For example, for inductive loads, slow melting fuses should be selected; For high-frequency circuits, fuses with fast response times should be selected.

　　4. Consider environmental factors: In high temperature, humid, or dusty environments, fuses with corresponding protection levels should be selected to ensure their long-term stable operation.

　　The difference between polymer PPTC and ceramic CPTC　　Positive temperature coefficient thermistor PTC (also known as self recovering fuse) is an overcurrent and over temperature protection component, which can be divided into two categories according to manufacturing materials: organic polymer PPTC and ceramic PTC (CPTC).　　Polymer PPTC is formed by extruding high molecular weight polymer into carbon powder. Carbon powder forms carbon chains for conductivity, and when heated, the polymer expands, causing the carbon chains to break and form high resistance. Ceramic CPTC is made by high-temperature sintering of barium titanate powder with positive temperature coefficient characteristics through electronic ceramic technology. Their commonality lies in their recoverability, which can be reused more than 6000 times.　　The main advantages of polymer PPTC are: zero power resistors at room temperature can be made very small, high current products only have a few milliohms, low power consumptio

　　Fuse resistance　　In addition to protecting the circuit, fuses themselves also have a certain resistance in the circuit.　　From the essence of resistance, the resistance of a fuse is determined by factors such as the conductivity, length, and cross-sectional area of its material. Generally speaking, the resistance of a fuse is relatively small, so that when normal current passes through, the voltage drop generated at both ends is small and will not have a significant impact on the normal operation of the circuit.　　In terms of materials, the resistivity of different materials varies. For example, the resistivity of materials such as lead tin alloys mentioned earlier determines the size of the fuse resistance. If it is a material with high electrical resistivity, the resistance of the fuse will be higher at the same length and cross-sectional area.　　From the perspective of length factor analysis, according to the law of resistance, under the same material and cross-sectional area, the lo

　　Working principle of fuse　　1、 Working principle of fuse　　When the fuse is powered on, the heat converted from electrical energy increases the temperature of the fusible item. When passing through normal operating current or allowable overload current, the heat generated is radiated to the surrounding environment through the melt and shell, and the heat generated by convection, conduction, etc. gradually balances with the generated heat. If the generated heat is greater than the dissipated heat, the excess heat will gradually accumulate on the meltable object, causing its temperature to rise; When the temperature reaches and exceeds the melting point of the meltable material, it will melt, melt, and cut off the current, playing a role in protecting the circuit.　　2、 Terminology of fuses　　Rated current: The nominal operating current of the fuse tube (the maximum current that the fuse can maintain normal operation for a long time under normal conditions).　　Rated voltage: The nominal oper

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.　　The self recovery fuse is connected in series in the circuit, and under normal circumstances, it is in a low resistance state to ensure the normal operation of the circuit; When a circuit experiences a short circuit or abnormally high current flows in, the self-heating of the self-healing fuse increases its impedance and limits the current to a sufficiently small amount, providing overcurrent protection.　　Self re
