Parameter Guide

Understand the key electrical and mechanical specifications for 1945R-03K.

Inductance
3.9 µH

1945R-03K has an inductance value of 3.9 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
1.2 A

1945R-03K is rated for 1.2 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)
190mOhm

1945R-03K lists a DC resistance of 190mOhm. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
