SMD Power Inductors Magnetic Resin Shielded Including LanTu Micro SNR4012-2R2MT for Current Handling
Magnetic Resin Shielded SMD Power Inductors
Product Overview
The SNR4012 Series are automatic assembly constructed power inductors, shielded with magnetic resin. This construction significantly reduces buzz noise to ultra-low levels. They feature large current handling capacity, low DC resistance, and metallization on the ferrite core for excellent shock resistance and durability. The closed magnetic circuit design minimizes leakage flux and Electromagnetic Interference (EMI), making them space-saving and power-efficient. These inductors are widely used in LED backlights, flat-screen TVs, notebooks, servers, graphic cards, automotive systems, and DC-DC converters.
