Parameter Guide

Understand the key electrical and mechanical specifications for SDR1305-221K.

Inductance
220 µH

SDR1305-221K 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
1 A

SDR1305-221K 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.

DC Resistance (DCR)
500mOhm Max

SDR1305-221K lists a DC resistance of 500mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.

Package / Case
