Parameter Guide
Understand the key electrical and mechanical specifications for SP1812R-183K.
SP1812R-183K has an inductance value of 18 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.
SP1812R-183K is rated for 613 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
SP1812R-183K lists a DC resistance of 680mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
SP1812R-183K uses a package or case of 1812 (4532 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
