471 capacitor Working Principle
A 471 capacitor operates based on the principle of capacitance, where it stores and releases electrical energy in the form of an electric field. It consists of two conductive plates separated by a dielectric material, such as ceramic. When a voltage is applied across its terminals, an electric field develops between the plates, allowing the capacitor to store charge.
The capacitance value, marked as 471 (470pF), determines its ability to store charge. In AC circuits, it impedes high-frequency signals, allowing it to filter noise. In DC circuits, it smooths voltage fluctuations by releasing stored energy when supply dips occur.
