A 33µH Inductor (Microhenry Fixed Power / RF Inductor) is a passive electronic component designed to store energy in a magnetic field, suppress high-frequency electrical noise, and smooth voltage ripple in power conversion circuits. Depending on the physical form factor—such as axial color-coded, radial drum core, SMD power inductor, or toroidal core—it uses a wrapped copper wire coil around a high-permeability ferrite core to deliver high saturation current capabilities with low DC resistance (DCR).

This component is featured by Famephase Electronic Accessories as an essential passive element for switch-mode power supplies (SMPS), DC-DC converters (buck, boost, and buck-boost topologies), LC low-pass filtering, RF decoupling, and general electronic prototyping on breadboards and PCBs.
