Product Description
Product Overview
The LANTU SNR4020 Series are automatic assembly, magnetic resin shielded SMD power inductors designed to minimize buzz noise to ultra-low levels. They feature a closed magnetic circuit design for reduced leakage flux and strong EMI resistance, large current capacity with low DC resistance, and metallization on the ferrite core for excellent shock resistance and durability. These space-saving and power-efficient inductors are ideal for a wide range of applications including LED backlights, flat-screen TVs, notebooks, servers, automotive products, and DC-DC converters.
