Notes

When ordering, please specify tolerance and screening codes: e.g. AR312RAB223JPZ.
Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
Q measured using an Agilent/HP 4291A with an Agilent/HP 16197A test fixture or equivalents.
SRF is measured on an Agilent 8753ES (or equivalent) with a Coilcraft CCF1236 test fixture.
DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a Coilcraft CCF1010 test fixture.
