Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for 21M331K.
21M331K has an inductance value of 3.3 µH. This value indicates how much magnetic energy the component can store and is one of the first parameters to compare when selecting an inductor.
21M331K is rated for 480 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
21M331K lists a DC resistance of 1Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
21M331K uses a package or case of Axial. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
