, the more important of the other indicators is the equivalent series resistance (ESR). Some capacitors have a gold ribbon line printed with a large hollow letter "I", which indicates that the capacitor belongs to the LOWNBSP;ESR low loss capacitance. Some capacitors also have an ESR value (equivalent series resistance), the lower the ESR, the smaller the loss, the greater the output current, the higher the quality of the capacitor. The esr is the abbreviation for Equivalentseriesresistance, th

have the expected effect of noise filtering and is helpless in the face of stubborn electromagnetic noise. One reason for this is that the effect of capacitor leads on the bypass effect is ignored. As shown in the Circuit Model 4-7 of the actual capacitor, it is a series network consisting of an equivalent inductance (ESL), a capacitor and an equivalent resistance (ESR. The impedance of the ideal capacitor decreases with the increase of the frequency
