Menene ESR na capacitor MLCC?

Idan ana maganar capacitors na MLCC (Multilayer Ceramic Capacitor), wani muhimmin siffa da za a yi la'akari da shi shine Equivalent Series Resistance (ESR). ESR na capacitor yana nufin juriyar ciki na capacitor. A wata ma'anar, yana auna yadda capacitor ke gudanar da alternating current (AC) cikin sauƙi.
