Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for SP43-221K.
SP43-221K has an inductance value of 220 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.
SP43-221K is rated for 400 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
SP43-221K lists a DC resistance of 1.932Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
SP43-221K uses a package or case of 2-SMD. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
