Fixed inductors store energy in a magnetic field and are essential for energy storage in DC-DC converters, EMI filtering in power supplies, signal conditioning in communication circuits, and current limiting in LED drivers. Our fixed inductor inventory spans wirewound, multilayer, thin-film, and ferrite-core types from Würth Elektronik, TDK (SLF/NLF series), Murata (LQH series), Coilcraft, Sumida, and Yageo — covering inductance values from 1 nH to 100 mH, current ratings from 10 mA to 50A, and packages from 0201 SMD to large through-hole chokes.
High-current power inductors for automotive 48V systems and shielded inductors for EMI-sensitive circuits face periodic allocation. Welllinkchips stocks both standard and hard-to-find inductor values and packages, including obsolete and end-of-life types used in industrial power supplies and legacy telecom equipment.
