Parameter Guide
Understand the key electrical and mechanical specifications for SP1812-333K.
SP1812-333K has an inductance value of 33 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.
SP1812-333K is rated for 408 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
SP1812-333K lists a DC resistance of 1.2Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
SP1812-333K uses a package or case of Nonstandard. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
