OverviewUse in analog circuitsUse in digital circuitsGimmick loopParasitic capacitive couplingSee alsoExternal links

In analog circuits, a coupling capacitor is used to connect two circuits such that only the AC signal from the first circuit can pass through to the next while DC is blocked. This technique helps to isolate the DC bias settings of the two coupled circuits. Capacitive coupling is also known as AC coupling and the capacitor used for the purpose is also known as a DC-blocking capacitor. A coupling capacitor''s ability to prevent a DC load from interfering with an AC source is particula…

How to Choose PCB Capacitor

Capacitors work in a special way. You can easily construct one by making use of aluminum foil sheets.Get two of these sheets and separate them using a shopping bag made of plastic. Next, connect the foil beneath the earth ground to the DC power supply''s negative terminal, and then connect the upper aluminum foil to the positive terminal of the power supply.
