Product Description
Product Overview
The CKST and CKSTT series are molded power inductors featuring a magnetic shield structure for strong electromagnetic interference (EMI) resistance and ultra-low buzzer noise. Designed for high-density installation, these inductors offer small volumes with large current capabilities, 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, firm structure, and high product precision. These inductors are ideal for applications such as PADs, laptops, desktops, servers, audio systems, networking equipment, security devices, mobile phones, smart home devices, and energy storage systems.
