SMD Power Inductors - 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, high saturation, and low resistance. Featuring a magnetic-resin shielded structure, these inductors significantly reduce buzz noise and provide excellent anti-EMI performance due to their closed magnetic circuit design which minimizes magnetic leakage flux. 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.
