Parameter Guide

Understand the key electrical and mechanical specifications for 7447709221.

Inductance
220 µH

7447709221 has an inductance value of 220 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
1.8 A

7447709221 is rated for 1.8 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)
300mOhm Max

7447709221 lists a DC resistance of 300mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.

Package / Case
