Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for ER1025-82KR.
ER1025-82KR has an inductance value of 390 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.
ER1025-82KR is rated for 40 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
ER1025-82KR lists a DC resistance of 35Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
ER1025-82KR uses a package or case of Axial. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
