Product Description
SMD Molding Power Inductor CKST, CKSTT Series
Product Overview
The CKST and CKSTT series are SMD molding power inductors designed for high-density installation and demanding environments. Featuring a magnetic shield structure, closed magnetic circuit, and strong anti-electromagnetic interference capabilities, these inductors offer ultra-low buzzer noise. Their compact size belies their high current handling capacity, maintaining excellent temperature rise and saturation current characteristics even in high-frequency and high-temperature conditions. Constructed with low-loss alloy powder die-casting, they exhibit low resistance, 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.
