Product Overview

The SNR5020 Series from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are magnetic resin shielded SMD power inductors designed for automatic assembly. These inductors feature a magnetic-resin shielded construction that significantly reduces buzz noise to ultra-low levels. They offer high current handling capabilities with low DC resistance, and their metallization on the ferrite core ensures excellent shock resistance and durability. The closed magnetic circuit design minimizes leakage flux and electromagnetic interference (EMI), leading to space savings and improved power efficiency. These inductors are widely used in applications such as LED backlights, flat-screen TVs, notebooks, desktop computers, servers, graphics cards, portable gaming devices, personal navigation systems, multimedia devices, automotive systems, telecommunication base stations, and DC-DC converters. They comply with RoHS, Halogen Free, and REACH standards.
