Product Description
Product Overview
The SNR5040 Series is an automatic assembly, magnetic resin shielded SMD power inductor designed for high-current applications with low DCR. Its closed magnetic circuit design minimizes flux leakage and enhances EMI resistance, while the magnetic-resin shielding significantly reduces buzz noise to ultra-low levels. This series offers space and power savings, making it suitable for a wide range of electronic devices including LED backlights, flat-screen TVs, notebooks, servers, graphics cards, automotive systems, and DC-DC converters. It is constructed with metallization on the ferrite core for excellent shock resistance and durability, and complies with RoHS, Halogen Free, and REACH standards.
