Parameter Guide
Understand the key electrical and mechanical specifications for SP1812-183G.
SP1812-183G 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.
SP1812-183G 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.
SP1812-183G lists a DC resistance of 680mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
SP1812-183G uses a package or case of Nonstandard. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
