Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SNR5030 Series is an automatic assembly constructed, magnetic resin shielded SMD power inductor. Designed for high performance and reliability, 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, excellent shock resistance, and strong EMI suppression thanks to a closed magnetic circuit design. Their compact size saves PCB real estate and reduces power consumption. These inductors are widely used in applications such as LED backlights, flat-screen TVs, notebooks, servers, automotive products, and DC-DC converters.
