The rectifier bridge circuit is a diode rectifier bridge. When the input voltage is in the positive half cycle of the AC voltage, the diode and the load resistor form a loop. The output of the rectifier bridge circuit is also a pulsating voltage that does not change in direction, but the pulsating f

Zinc oxide varistor cannot tolerate over-voltage or long-term power frequency voltage, short circuit and breakdown failure will occur, and thermal breakdown (large current) will occur. The varistor just replaced also broke down. The damage of varistor can be divided into two categories:1. The produc

There are three places in the car that use capacitors: energy storage, motor and electronic control. In the design of the power supply part of new energy vehicles, it is necessary to use high-voltage capacitors for smoothing and filtering. The internal working environment of the automobile is harsh,

Thermistors are typically characterized by temperature sensitivity and exhibit different resistance values at different temperatures. The higher the resistance of the PTC at higher temperatures, the lower the resistance value of the NTC at higher temperatures, which are all semiconductor devices. Au

Sintering temperature refers to the temperature at which the refractory material or ceramic green body reaches the minimum porosity, the largest shrinkage, the most compact product, the best performance, or a solid aggregate state through sintering. The temperature during sintering is called sinteri

Monolithic ceramic capacitor is abbreviated as MLCC. It is widely used in electronic precision instruments, and various small electronic devices for resonance, coupling, filtering and bypass. The monolithic ceramic capacitor has good temperature and frequency characteristics. As the frequency rises,

Capacitor is an important electronic component in the circuit. Pay attention to protection when using it to prolong its service life. Test the sealing pressure endurance and the leakage current at the time of purchase. Check the capacitance of the capacitor to avoid the capacitance being too low, wh

Film capacitors are used more and more widely, and their performance and quality are getting better and better. What problems are worth noting during operation? The problems with film capacitors can be divided into: failure, pin pitch problems, unclear printing, unsuitable volume, etc. The common pr

Thermistors are divided into positive temperature coefficient (PTC) and negative temperature coefficient (NTC) according to different temperature coefficients. The positive temperature coefficient has a higher resistance value at higher temperatures, and the negative temperature coefficient has a lo

Capacitors are important electronic components in a circuit. Pay attention to protection when using. Make it as long as possible. At the same time, film capacitors are important capacitors and are one of the electronic components used extensively in electronic equipment. It is widely used in circuit
