Product Overview
The CKST/CKSTT series SMD Molding Power Inductors are designed for high-density installation and offer strong anti-electromagnetic interference with ultra-low buzzing. These compact inductors deliver large current capabilities and maintain excellent temperature rise and saturation current characteristics in high-frequency and high-temperature environments. Constructed with low-loss alloy powder die-casting, they feature low resistance, a firm structure, and high product precision. Applications include PADs, laptops, desktops, servers, audio equipment, networking devices, security systems, mobile phones, smart home devices, and energy storage equipment.
