Product Overview
The SNR4030 Series Magnetic Resin Shielded SMD Power Inductors are designed for automatic assembly and feature a magnetic-resin shielded construction that significantly reduces buzz noise to ultra-low levels. These inductors offer large current handling capability with low DC resistance, and their closed magnetic circuit design minimizes leakage flux and enhances EMI resistance. The metallization on the ferrite core provides excellent shock resistance and durability. They are space-saving and power-efficient, suitable for a wide range of applications including LED backlights, flat-screen TVs, notebooks, servers, automotive products, and DC-DC converters. They comply with RoHS, Halogen Free, and REACH standards.
