The symbol "µF" stands for microfarad, a unit of measurement used to quantify capacitance in electrical components. Capacitance is the ability of a component, such as a capacitor, to store electrical energy. One microfarad is equal to one-millionth of a farad, which is the standard unit of capacitance. Microfarads are commonly used in various electronic devices, including capacitors found in power supplies and audio equipment. These components help regulate voltage and filter signals, ensuring that devices operate efficiently and reliably. Understanding microfarads is essential for anyone working with electronics or electrical engineering.
