Parameter Guide
Understand the key electrical and mechanical specifications for ER1641-123KS.
ER1641-123KS has an inductance value of 12 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.
ER1641-123KS is rated for 200 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
ER1641-123KS lists a DC resistance of 2Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
ER1641-123KS uses a package or case of Axial. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
