SMD Molding Power Inductor - CKST/CKSTT Series
Product Overview
The CKST and CKSTT series are high-performance SMD molding power inductors designed for demanding applications. Featuring a magnetic shield structure with a closed magnetic circuit, these inductors offer strong electromagnetic interference (EMI) resistance and ultra-low buzzer noise, enabling high-density installation. They are engineered for 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. These inductors are ideal for a wide range of applications including PADs, notebooks, desktops, servers, audio equipment, networking devices, security systems, mobile phones, smart home devices, and energy storage equipment.
