Inductance Measured at 1V with no DC current
Incremental Current The current at which the inductance
will be decreased by a maximum of 5% from its initial zero DC value.
Marking API/SMD; inductance with units and tolerance followed by an SP; date code (YYWWL). Note: An R before the date code indicates a RoHS component. Example: P1812-182K
