Parameter Guide

Understand the key electrical and mechanical specifications for PTKM50-40SM.

Inductance
50 µH

PTKM50-40SM has an inductance value of 50 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
1.9 A

PTKM50-40SM is rated for 1.9 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)
110mOhm Max

PTKM50-40SM lists a DC resistance of 110mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.

Package / Case
