Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SNR6028 Series are automatic assembly constructed, magnetic resin shielded SMD power inductors. Designed to reduce buzz noise to ultra-low levels, these inductors feature a closed magnetic circuit for minimal leakage flux and strong EMI resistance. They offer large current handling capabilities with low DC resistance, saving PCB space and power. The metallization on the ferrite core ensures excellent shock resistance and durability. These inductors are widely used in applications such as LED backlights, flat-screen TVs, set-top boxes, notebooks, desktop computers, servers, graphic 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.
