Parameter Guide

Understand the key electrical and mechanical specifications for 7447730.

Inductance
1 µH

7447730 has an inductance value of 1 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
4 A

7447730 is rated for 4 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)
49mOhm Max

7447730 lists a DC resistance of 49mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.

Package / Case
Nonstandard

7447730 uses a package or case of Nonstandard. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
