Parameter Guide

Understand the key electrical and mechanical specifications for 5500R-125J.

Inductance
1.2 mH

5500R-125J has an inductance value of 1.2 mH. 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
1.01 A

5500R-125J is rated for 1.01 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)
977mOhm Max

5500R-125J lists a DC resistance of 977mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.

Package / Case
