Product Description
Product Overview
The CKST and CKSTT series are SMD molding power inductors designed for high-density installation and robust performance. These inductors feature a magnetic shield structure with a closed magnetic circuit, providing strong electromagnetic interference (EMI) resistance and ultra-low buzzing. They are engineered for compact size while delivering large current capacity, maintaining excellent temperature rise and saturation current characteristics even in high-frequency and high-temperature environments. Constructed with low-loss alloy powder die-casting, they offer low resistance, firm structure, and high product precision. Applications include PADs, laptops, desktops, servers, audio equipment, networking devices, security systems, mobile phones, smart home devices, and energy storage equipment.
