  • Decoupling Capacitor : Design, Differences and Its Uses

    What is a Decoupling Capacitor? A decoupling capacitor (also called a bypass capacitor) is a capacitor which is used to decouple AC signals from a DC signal. While coupling capacitors are used to pass through the AC component while blocking the DC component, a decoupling capacitor removes the AC component, making for a more pure DC component.
