CENKER CKCS201610-6.8uH M Compact Inductor with Closed Magnetic Circuit and Low Magnetic Leakage Flux
SMD Power Inductor - CKCS Series
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, making them ideal for demanding applications. The magnetic-resin shielded structure significantly reduces buzz noise to ultra-low levels, while the closed magnetic circuit design minimizes magnetic leakage flux and enhances anti-EMI performance. Compared to traditional inductors of the same size, the CKCS Series offers over 30% higher rated current.
