Parameter Guide
Understand the key electrical and mechanical specifications for 4379-221KS.
4379-221KS has an inductance value of 220 nH. This value indicates how much magnetic energy the component can store and is one of the first parameters to compare when selecting an inductor.
4379-221KS is rated for 1 A. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
4379-221KS lists a DC resistance of 40mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
4379-221KS uses a package or case of Nonstandard. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
