Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for 5900-121-RC.
5900-121-RC has an inductance value of 120 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.
5900-121-RC is rated for 2.1 A. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
5900-121-RC lists a DC resistance of 97mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
5900-121-RC uses a package or case of Axial. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
