This technical report explores the critical role of the inductor as the primary component for signal reconstruction and filtering within Class-D audio amplifiers. It explains how these devices utilize electromagnetic physics to transform high-frequency digital pulses back into high-fidelity analog waves. The text examines the materials science of magnetic cores, contrasting affordable iron powder options with premium gapped ferrites and advanced alloys that reduce hysteresis and distortion. Additionally, it details how conductor geometries, such as Litz wire, are employed to mitigate the skin effect and improve efficiency. Ultimately, the source serves as an exhaustive guide on how inductor design dictates the boundary between basic consumer electronics and reference-grade audio performance.
