Parameter Guide
Understand the key electrical and mechanical specifications for SP1812R-222K.
SP1812R-222K 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.
SP1812R-222K is rated for 1.17 A. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
SP1812R-222K lists a DC resistance of 150mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
SP1812R-222K uses a package or case of 1812 (4532 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
