Parameter Guide

Understand the key electrical and mechanical specifications for ER1641-183KS.

Inductance
18 µH

ER1641-183KS has an inductance value of 18 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
300 mA

ER1641-183KS is rated for 300 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)
890mOhm Max

ER1641-183KS lists a DC resistance of 890mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
