SMD Semi-shielded Power Inductor | High Current Power Inductor Manufacturer | Coilmaster Electronics
Manufacturer of SMD Resin Shielded Power Inductor. SMD semi-shielded inductors offer a unique balance between fully shielded and non-shielded inductors, making them an ideal choice for applications requiring moderate EMI control without the added weight or cost of a completely enclosed design. In these inductors, a wound drum core is covered and molded with magnetic epoxy—an epoxy resin blended with soft magnetic metal powder. This construction functions similarly to a ring core in fully shielded solutions, but does not completely enclose the winding, resulting in a more compact and lighter component compared to fully shielded inductors. Coilmaster Electronics is a high-current High Current Power Inductors, Automotive Grade Chokes & Inductors,High Frequency and Planar Transformers, LAN Magnetics (RJ45), Multilayer Chip Beads manufacturer from Taiwan since 1995. Coilmaster offers AEC-Q200 certified, high-efficiency power inductors, chokes, and transformers. Specializing in low-loss, high-current components for Automotive, 5G, and Industrial applications. Contact our experts for instant support. With more than 20 years of experience in magnetic territory, Coilmaster Electronics is specialized in the production of SMD power inductors, common mode choke, high frequency transformers.

SMD semi-shielded inductors offer a unique balance between fully shielded and non-shielded inductors, making them an ideal choice for applications requiring moderate EMI control without the added weight or cost of a completely enclosed design. In these inductors, a wound drum core is covered and molded with magnetic epoxy—an epoxy resin blended with soft magnetic metal powder. This construction functions similarly to a ring core in fully shielded solutions, but does not completely enclose the winding, resulting in a more compact and lighter component compared to fully shielded inductors.
With SMD semi-shielded inductors, engineers can effectively reduce EMI while optimizing weight, board space, and overall cost. By leveraging either ferrite or alloy powder cores, these inductors cater to a broad spectrum of power designs, providing a convenient middle ground between fully shielded and non-shielded configurations.
Features
- Magnetic Epoxy Shield:Acts as a partial shield to reduce EMI while allowing for a smaller, lighter package. / Helps maintain the inductor’s stability and performance throughout its operating life.
- Moderate Flux Radiation & Cost-Effectiveness:Provides medium-level flux radiation and space efficiency at a lower cost than fully shielded inductors. / Offers better EMI performance than non-shielded types, striking a cost–performance balance. / A practical choice for less radiation-sensitive applications where moderate EMI containment is sufficient.
- Broad Dimension Range & Customization: Available in various package sizes from 2.0 mm to 8.0 mm, accommodating diverse layout requirements. / Custom inductance values can be developed to meet specific design criteria or unique application needs.
Applications
- Consumer Electronics demanding smaller form factors yet decent EMI suppression
- Power Modules, DC-DC Converters, and Battery-Powered Devices needing reduced heat generation and stable operation
- Automotive Subsystems where moderate EMI performance is sufficient, plus space and cost considerations are critical
- Industrial Controls requiring balance between cost, size, and electromagnetic compatibility
