Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for 1945-21G.
1945-21G 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.
1945-21G is rated for 170 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
1945-21G lists a DC resistance of 5Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
1945-21G uses a package or case of Axial. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
