Shielded Radial Lead Power Inductors, Power Chokes - RDS / RCS series
Shielded THT Power Chokes with Low Flux Leakage & High EMI Suppression
Coilmaster’s Shielded Radial Power Inductors (RDS/RCS) utilize molded or ring-core shielding for a magnetically enclosed structure. This design significantly reduces flux leakage and ensures superior EMI control, while maintaining high Q and SRF. Available in compact to large formats (e.g., 875 to 1318), they are the necessary upgrade for engineers requiring high current stability, better noise suppression, and layout cleanliness than unshielded types.
The necessary choice for high-frequency switching regulators and power circuits located near sensitive Analog or High-Speed Digital ICs. When near-field magnetic interference suppression, critical EMC compliance, or PoE circuit stability is non-negotiable, shielded RDS/RCS inductors offer the best-in-class reliability and significantly lower magnetic interference compared to unshielded chokes.
