Parameter Guide
Understand the key electrical and mechanical specifications for SP1812R-392K.
SP1812R-392K has an inductance value of 3.9 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-392K is rated for 1 A. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
SP1812R-392K lists a DC resistance of 200mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
SP1812R-392K uses a package or case of 1812 (4532 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
