A Leaded Inductor is a through-hole component with axial or radial wire terminals, designed for high-power, high-reliability circuits requiring robust mechanical stability. Featuring a wound magnetic core (e.g., ferrite, powdered iron) encapsulated in epoxy or thermoplastic, it delivers inductance values from µH to mH with high current ratings (up to tens of amps), ideal for linear power supplies, motor drives, automotive systems, and industrial equipment. Its durable construction resists vibration and thermal stress, while straightforward mounting suits prototyping, repair, or applications where SMD compatibility is secondary. Customizable winding configurations and core materials ensure adaptability to AC/DC filtering, energy storage, and noise suppression in harsh environments.
