Parameter Guide
Understand the key electrical and mechanical specifications for 5731.
5731 has an inductance value of 40 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.
5731 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.
5731 lists a DC resistance of 25mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
5731 uses a package or case of Radial, Vertical (Open). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
