The SNR4030 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 design significantly reduces buzz noise to ultra-low levels, offers large current handling with low DC resistance, and provides excellent shock resistance and damage-free durability due to metallization on the ferrite core. The closed magnetic circuit design minimizes leakage flux and electromagnetic interference (EMI), while the compact size saves PCB real estate and power. These inductors are widely used in applications such as LED backlights, flat-screen TVs, notebooks, servers, graphic cards, automotive products, and DC-DC converters.
