Parameter Guide
Understand the key electrical and mechanical specifications for 4379R-221HS.
4379R-221HS 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.
4379R-221HS 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.
4379R-221HS lists a DC resistance of 40mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
4379R-221HS uses a package or case of 2-SMD. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
