Product Overview
The CKCS Series SMD Power Inductors are designed for surface mounting, offering a compact and ultra-thin form factor with high power handling capabilities, high saturation, and low resistance. Featuring a magnetic-resin shielded structure and a closed magnetic circuit, these inductors significantly reduce buzz noise and magnetic leakage, providing strong anti-EMI performance. They offer a rated current over 30% higher than traditional inductors of the same size. Ideal for applications such as PADs, notebooks, servers, audio equipment, networking devices, security systems, mobile phones, smart home devices, and energy storage equipment.
