The main technical indicators of capacitors are capacitance, withstand voltage and temperature. In addition to these three main indicators, the more important of other indicators is equivalent series resistance (ESR). Some capacitors have a golden strip line with a big hollow letter "I" printed on it, which indicates that the capacitor is a LOW ESR low-loss [...]
The role of electrolytic capacitors In the power supply circuit, the rectifier circuit turns AC into pulsating DC, and a larger capacity electrolytic capacitor is connected after the rectifier circuit. Using its charge and discharge characteristics, the rectified pulsating DC voltage becomes a relatively stable DC Voltage. In practice, in order to prevent the supply voltage [...]
