Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for SP1210R-123K.
SP1210R-123K 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.
SP1210R-123K is rated for 400 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
SP1210R-123K lists a DC resistance of 1.3Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
SP1210R-123K uses a package or case of 1210 (3225 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
