Parameter Guide

Understand the key electrical and mechanical specifications for ER1025-50KR.

Inductance
18 µH

ER1025-50KR 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
145 mA

ER1025-50KR is rated for 145 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)
3.1Ohm Max

ER1025-50KR lists a DC resistance of 3.1Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.

Package / Case
