Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for ER1537-20KS.
ER1537-20KS has an inductance value of 2.2 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.
ER1537-20KS is rated for 435 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
ER1537-20KS lists a DC resistance of 950mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
ER1537-20KS uses a package or case of Axial. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
