Product Overview
The CKCS Series SMD Power Inductors are designed for surface mounting, offering a compact and ultra-thin profile with high power handling capabilities. These inductors feature high saturation and low resistance, enhanced by a magnetic-resin shielded structure that significantly reduces noise and provides strong anti-EMI performance due to a closed magnetic circuit design with minimal magnetic leakage. Compared to traditional inductors of the same size, the CKCS Series offers over 30% higher rated current. They are suitable for a wide range of applications including PADs, notebooks, servers, audio equipment, networking devices, security systems, mobile phones, smart home devices, and energy storage equipment.
