In the world of electronics, capacitors play a crucial role in ensuring the optimal functioning of printed circuit boards (PCBs). Among these, decoupling and bypass capacitors are integral components that help mitigate noise and stabilize voltage levels. Decoupling Capacitors: An Overview A decoupling capacitor, also referred to as a bypass capacitor or power filter capacitor, is an electronic device used to mitigate or eliminate noise and voltage variations in electronic circuits. These capacitors are strategically placed near integrated circuits (ICs) to provide a low-impedance path for high-frequency noise generated by the ICs. By reducing noise, decoupling capacitors enhance the overall performance and reliability of electronic devices. Decoupling capacitors are often employed in digital circuits, microprocessors, and other high-speed electronics. They come in various types and values, with the specific choice based on the circuit requirements. Ceramic, tantalum, and aluminum elect...
