Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for 21M221K.
21M221K has an inductance value of 2.2 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.
21M221K is rated for 680 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
21M221K lists a DC resistance of 500mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
21M221K uses a package or case of Axial. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
