Parameter Guide

Understand the key electrical and mechanical specifications for ER17S123KR.

Inductance
120 µH

ER17S123KR has an inductance value of 120 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
150 mA

ER17S123KR is rated for 150 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)
3.6Ohm Max

ER17S123KR lists a DC resistance of 3.6Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
