Top 10 shielded power inductor Manufacturers

January 13, 2026

Shielded power inductors are compact, low-profile components used in power supplies and DC-DC converters to filter noise and store energy. Their magnetic shielding minimizes electromagnetic interference (EMI), enhancing performance in high-density electronics. Widely used in consumer electronics, automotive systems, and industrial equipment, they offer high efficiency, stable inductance, and excellent thermal performance. Ideal for applications requiring reduced EMI and space-saving designs.
