SMD Power Inductors - CKCS Series
Product Overview
The CKCS Series represents a line of surface-mount, compact, and ultra-thin power inductors designed for high-power applications. These inductors feature high saturation capabilities and low resistance. Their magnetic-resin shielded structure significantly reduces buzz noise to ultra-low levels, while the closed magnetic circuit design minimizes magnetic leakage flux, providing strong anti-EMI performance. 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.
