Product Overview

The SNR4018 Series by SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. is an automatic assembly constructed, magnetic resin shielded SMD power inductor. Engineered for high performance, it significantly reduces buzz noise to ultra-low levels due to its magnetic-resin shielded construction. Key benefits include large current handling capacity, low DC resistance, excellent shock resistance and durability from metallization on the ferrite core, and strong EMI suppression thanks to its closed magnetic circuit design. This series is designed for space and power efficiency, making it ideal for a wide range of applications including LED backlights, flat-screen TVs, notebooks, servers, automotive products, and DC-DC converters.
