请问电容的ESR代表什么意思?谢谢
ESR, Equivalent Series Resistance, 电容的等效串联电阻.ESR is the sum of in-phase AC resistance. It includes resistance of the dielectric, plate material, electrolytic solution, and terminal leads at aparticular frequency. ESR acts like a resistor in series with a capacitor (thus the name Equivalent Series Resistance). This resister can cause circuits to fail that look just fine on paper and is often the failure mode of capacitors. 实际应用中多希望ESR越小越好,ESR的大小将影响电容的AC频率特性,系统的稳定性、瞬态特性等.
