　　Can surge thyristors and discharge tubes only be used for transient overvoltage protection, while polymer positive temperature coefficient self recovery fuses can only be used for overcurrent protection? So what is the maximum current and voltage they can withstand?

　　Generally speaking, traditional overvoltage protection devices are mainly used for transient overvoltage protection, but they are also suitable for long-term voltage stabilization conditions that do not exceed their rated power.

　　Self recovery fuses can not only be used for overcurrent protection, but also for temperature protection or protection under the combined action of current/temperature. In addition, they can also be used in conjunction with IC for temperature detection and feedback of temperature signals for protection.

　　At present, the maximum voltage that the self recovery fuse can withstand is 600Vrms, and the maximum holding current is 15A; The maximum voltage of PPTC for automobiles is 60Vdc, and the maximum holding current is 15A.

　　　　1. Product certification. For example, exporting to North America requires UL or CSA certification. At present, products exported to Europe still need to comply with the RoHs directive of the European Union, which is commonly referred to as environmental certification such as SGS.　　2. The normal working current of the circuit. The working current through the fuse should not exceed 75% of the rated current of the fuse.　　3. The applied voltage applied to the fuse. Usually, patch fuses are used in portable devices, and the working voltage of the circuit is generally not high. As long as the rated voltage of the patch fuse is higher than the working voltage of the circuit, it can be used with confidence.　　4. The ambient temperature of the fuse. When applying patch fuses to portable devices, appropriate consideration should be given to the temperature rise of the fuse, that is, the reduction of the rated current of the fuse. The ambient temperature during fuse operation should be within

　　Several common car fuses　　1. Plug-in fuse　　According to the different rated currents, there are several types of fuses, including ultra small plug-in fuses, small car fuses, medium car fuses, and large car fuses. The rated current ranges from 1-40 amperes (A) to large 30-120 amperes (A), and the rated voltage is 32 volts (V).　　When using a vehicle, friends may occasionally find that some electrical appliances are not working, such as the headlights not turning on or the wipers not moving. In this case, you should first check the fuse to see if it is damaged. So, where are these fuses? What does it look like?　　The fuses of various circuits in a car are usually centrally arranged in a safe box. The position of the safe box may vary for different models of vehicles, and it appears as a small black plastic box. In your car manual, you can find where the car fuse panel is located, and most car designers will place the car fuse panel on the side of the dashboard or in the engine compartmen

　　Technical standard for PPTC self recovery fuse　　1. Rated zero power resistor　　PPTC thermistors should be packaged as zero power resistors, and the resistance range should be indicated on the outer packaging. After withstand voltage and withstand current tests, the range of resistance change rate of each group of samples before themselves is δ | Ri before Ri/Ri before - (Rj before Rj)/Rj before | ≤ 100%　　2. PTC effect　　Saying that a material has a PTC (positive temperature coefficient) effect means that the material's resistance increases with increasing temperature. For example, most metal materials have PTC effect. In these materials, the PTC effect is manifested as a linear increase in resistance with increasing temperature, which is commonly referred to as the linear PTC effect.　　3. Nonlinear PTC effect　　Materials undergoing phase transition will exhibit a phenomenon of rapid increase in resistance within a narrow temperature range of several to ten orders of magnitude, known as t

　　How to replace car fuses?　　Replacing car fuses is a relatively simple but very important maintenance task. The correct replacement steps are as follows:　　1. Prepare tools: Usually only a small screwdriver or a specialized fuse removal tool is needed.　　2. Turn off the engine and all electrical equipment: Ensure that the vehicle is turned off and all electrical equipment (such as lights, audio, etc.) is turned off.　　3. Find the fuse box: Most vehicles' fuse boxes are located under the dashboard or engine hood in the cockpit. The specific location can be found in the vehicle's user manual.　　4. Identify faulty fuses: Open the fuse box and check the status of each fuse. A faulty fuse usually has a clear broken line.　　5. Remove the faulty fuse: Use a screwdriver or specialized tool to gently clamp both ends of the fuse and pull it out. Be careful not to apply too much force to avoid damaging the fuse box.　　6. Install a new fuse: Select a new fuse with the same rated current and insert it i

　　Characteristics of PPTC fuses　　1. High power-off capability: PPTC fuses can provide high power-off capability in a small volume. They can withstand high currents, ensuring the normal operation of the circuit while protecting it.　　2. Low voltage drop: PPTC fuses have the characteristic of low voltage drop and will not cause energy loss under normal working conditions.　　3. Wide working temperature range: PPTC fuses can work normally in a wide temperature range and adapt to the needs of different environments.　　Disadvantages of PPTC fuses　　1. High internal resistance: Due to the self recovery characteristics of PPTC fuses, their internal resistance will significantly increase in the protected state. This may have a certain impact on the performance of the circuit, especially in applications that require low resistance.　　2. Trigger time delay: Although PPTC fuses have a relatively fast response time, their trigger time may be delayed compared to traditional fuses. In applications where r
