Inductors in the Electronics category are passive components that store energy in a magnetic field when electrical current flows through them. They are typically constructed as coils of wire and are used to block or filter alternating current (AC) in circuits, while allowing direct current (DC) to pass. Inductors are key in various applications such as in power supplies, radio frequency (RF) circuits, and audio electronics, where they are used for smoothing power delivery, tuning circuits, and managing signal integrity. Their ability to react to changes in current makes them essential for maintaining the efficiency and performance of electronic systems, particularly in minimizing noise and stabilizing voltage.
