The SNR4012 Series by SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. is an automatic assembly compatible, magnetic resin shielded SMD power inductor. It features a magnetic-resin shielded construction that significantly reduces buzz noise to ultra-low levels. Designed for large current and low DCR applications, it boasts metallization on the ferrite core for excellent shock resistance and durability. The closed magnetic circuit design minimizes leakage flux and enhances EMI resistance, while its compact size saves PCB space and power. This series is widely used in various electronic devices including LED backlights, flat-screen TVs, notebooks, servers, graphics cards, multimedia devices, automotive products, and DC-DC converters.
