Product Description
Product Overview
The CKST and CKSTT series are SMD molding power inductors designed for high-density installation. These inductors feature a magnetic shield structure with a closed magnetic circuit, providing strong anti-electromagnetic interference and ultra-low buzzing. They are engineered for small volume with 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. These power inductors are suitable for a wide range of applications including PADs, notebooks, desktops, servers, audio equipment, network devices, security systems, mobile phones, smart home devices, and energy storage equipment.
