Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for 4649.
4649 has an inductance value of 550 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.
4649 is rated for 160 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
4649 lists a DC resistance of 13Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
4649 uses a package or case of Axial. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
