Parameter Guide

Understand the key electrical and mechanical specifications for SDR7045-221K.

Inductance
220 µH

SDR7045-221K 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.

Current Rating
500 mA

SDR7045-221K is rated for 500 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.

DC Resistance (DCR)
930mOhm Max

SDR7045-221K lists a DC resistance of 930mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
