Notes

When ordering, please specify screening code: e.g. AR312RAM103JPZ.
Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP 4286A impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
Q measured at the same frequency as inductance using an Agilent/ HP 4291A with an Agilent/HP 16197A test fixture or equivalents.
SRF measured using an Agilent/HP 8753ES network analyzer or equivalent and a Coilcraft SMD-D test fixture.
DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a Coilcraft CCF1010 test fixture.
