Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SNR4018 Series are automatic assembly, magnetic resin shielded SMD power inductors designed for high-performance applications. These inductors significantly reduce buzz noise to ultra-low levels due to their magnetic-resin shielded construction. They offer large current handling capabilities with low DC resistance, a closed magnetic circuit design for reduced leakage flux and EMI, and metallization on the ferrite core for excellent shock resistance and durability. Their compact size saves PCB real estate and power. These inductors are widely used in LED backlighting, flat-screen TVs, notebooks, servers, graphics cards, automotive products, and DC-DC converters.
