Parameter Guide

Understand the key electrical and mechanical specifications for 3090R-391K.

Inductance
390 nH

3090R-391K has an inductance value of 390 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.

Current Rating
500 mA

3090R-391K 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)
300mOhm Max

3090R-391K lists a DC resistance of 300mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.

Package / Case
