Notes

When ordering, please specify tolerance, termination and testing codes: e.g. CP312RAB822JLZ.
Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP4286A 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 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.

Tolerance:

G = 2%
J = 5%

Termination:

L = Silver-palladium-platinum-glass frit.
T = Tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = Tin-lead (63/37). (Special order, added cost)

Testing:

Z = Unscreened
H = Group A screening per Coilcraft CP-SA-10001

All screening performed to the document’s latest revision.
