What Are Decoupling Capacitors?
As you likely know, capacitors are used in electronic circuits to provide local energy storage and stabilize power supply voltage. Decoupling capacitors are a specific type of capacitor used to isolate or decouple two circuits. In other words, these capacitors decouple AC signals from DC signals or vice versa..

OverviewDiscussionDecouplingSwitching subcircuitsTransient load decouplingPlacementExample usesSee also
In electronics, a decoupling capacitor is a capacitor used to decouple (i.e. prevent electrical energy from transferring to) one part of a circuit from another. Noise caused by other circuit elements is shunted through the capacitor, reducing its effect on the rest of the circuit. For higher frequencies, an alternative name is bypass capacitor as it is used to bypass the power supply or other high-impedance
