Parameter Guide
Understand the key electrical and mechanical specifications for ER1641-102KR.
ER1641-102KR has an inductance value of 1 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.
ER1641-102KR is rated for 1.07 A. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
ER1641-102KR lists a DC resistance of 70mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
ER1641-102KR uses a package or case of Axial. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
