Low DC Resistance Magnetic Resin Shielded SMD Power Inductor LanTu Micro SNR4018-1R5MT for Automotive and Server
Product Overview
The SNR4018 Series is an automatic assembly compatible, magnetic resin shielded SMD power inductor designed to minimize buzz noise to ultra-low levels. It features a closed magnetic circuit design for reduced leakage flux and strong EMI resistance, along with metallization on the ferrite core for excellent shock resistance and damage-free durability. These inductors offer large current handling capability, low DC resistance, and a space-saving, power-efficient design. They are widely used in applications such as LED backlights, flat-screen TVs, notebooks, desktop computers, servers, graphics cards, portable gaming devices, personal navigation systems, multimedia devices, automotive products, and DC-DC converters. The series complies with RoHS, Halogen Free, and REACH standards.
