Product Overview
The SNR5040 Series Magnetic Resin Shielded SMD Power Inductors from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are automatic assembly constructed power inductors featuring magnetic resin shielding. This construction significantly reduces buzz noise to ultra-low levels, offers large current handling with low DCR, and provides excellent shock resistance due to metallization on the ferrite core. The closed magnetic circuit design minimizes leakage flux and enhances EMI resistance, while the compact size saves PCB space and power. These inductors are widely used in applications such as LED backlights, flat-screen TVs, notebooks, servers, graphics cards, automotive products, and DC-DC converters.
