Class D Inductors

Class D Inductors

Engineered for high-efficiency switching and superior signal integrity, ICE’s Class D inductors suit a range of compact designs. These through-hole inductors use ferrite cores to minimize EMI and switching losses, making them ideal for Class D audio amplifiers and point-of-load (POL) converters where clean signal integrity and thermal performance are essential.

ICE’s 1D inductors are available in five series — from the compact 1D10A series to the larger 1D31A series — each offering the same inductance value with a range of current ratings and DCR options. This shared electrical profile across multiple footprints gives designers the flexibility to scale performance without redesigning the circuit.

For deeper technical insight, ICE’s Class D Application Note highlights how ferrite-based inductors directly influence audio fidelity, efficiency, and EMI performance in amplifier designs. It outlines key selection parameters such as inductance value, saturation current, and DCR, while demonstrating how the 1D series provides reliable solutions across different power levels and design constraints.
