Product Overview
The SNR4030 Series Magnetic Resin Shielded SMD Power Inductors from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are automatic assembly constructed power inductors designed for high performance and reliability. Featuring a magnetic-resin shielded construction, these inductors significantly reduce buzz noise to ultra-low levels. They offer large current handling capabilities with low DC resistance, and their closed magnetic circuit design minimizes leakage flux and enhances Electro Magnetic Interference (EMI) resistance. The metallization on the ferrite core provides excellent shock resistance and damage-free durability, making them space-saving and power-efficient. These inductors are widely used in applications such as LED backlights, flat-screen TVs, notebooks, servers, graphic cards, automotive products, and DC-DC converters.
