Product Description
Product Overview
The CKST and CKSTT series are molded power inductors featuring a magnetic shield structure with a closed magnetic circuit, offering strong electromagnetic interference (EMI) resistance and ultra-low buzzing. These inductors are designed for high-density installation and excel in 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 provide low resistance, a firm structure, and high product precision. They are ideal for applications such as PADs, notebooks, desktops, servers, audio systems, networking equipment, security devices, mobile phones, smart home devices, and energy storage equipment.
