Power inductors for 800G / 1.6T optical modules

Power delivery inside a transceiver

Optical modules convert a narrow input rail into the multiple low-voltage supplies their DSPs, drivers and TIAs demand. Board area is measured in square centimetres, the thermal budget is razor-thin, and any magnetic leakage couples straight into sensitive analog circuitry. The inductor is rarely the loudest component on the BOM — but it is often the one that decides whether the design passes EMI and thermal validation.

What module makers need from the inductor

• Shielded construction — molded one-piece bodies keep magnetic leakage off DSP and TIA traces
• Low DCR in small footprints — efficiency where the thermal budget is nearly zero
• Soft saturation — margin against startup and protection-mode current spikes
• Reflow robustness — parts that survive production without cracking or shifting
• Stable supply at volume — AI demand curves are unforgiving on lead times

Our offering for module designs

Our molded SMD inductor family covers the compact POL stages in most module architectures, while co-fired parts serve the highest-current rails in 1.6T-class designs. Custom inductance values and heights are available where standard parts don't fit the layout.
