SMD Shielded Power Inductor (SDS SERIES)
SDS Series: Low-Profile Shielded SMD Inductors (Low EMI, Multi-Core Options)
The SDS Series are shielded power inductors designed for stable DC-DC conversion in a wide range of compact electronics. By utilizing a magnetically sealed drum-core structure, the SDS family minimizes EMI leakage while maintaining reliable energy storage and bias characteristics. Its closed magnetic path construction ensures consistent inductance accuracy in noise-sensitive circuits, while offering a cost-efficient solution for mainstream power applications.
The SDS platform is optimized for flexible design requirements, offering multiple ferrite options (Ni-Zn and Mn-Zn), a broad inductance range, and a wide selection of industry-standard footprints from 3.0 mm to 12.0 mm. Each option delivers a different balance of DCR, saturation current, and voltage capability, enabling engineers to match performance to specific cost, size, or power targets. Custom inductance values are available for footprint-compatible replacements.
Select SDS when a cost-optimized shielded inductor is required without redesigning the PCB footprint.
Core & Performance Options
Multiple core materials are selectable based on efficiency or current requirements. Ni-Zn cores offer strong EMI suppression and stable performance for standard DC-DC stages, while Mn-Zn cores provide higher current capability with reduced DCR—ideal for higher-power designs.
