Notes

When ordering, please specify termination and testing codes: e.g. ST413RAB104JLZ.
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 16197 test fixture or equivalents.
SRF measured using an Agilent/HP 8753ES network analyzer or equivalent with a Coilcraft SMD-D fixture.
DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a Coilcraft CCF858 test fixture.

Termination:

L = Silver-palladium-platinum-glass frit.
T = Tin-silver-copper (95.5/4/0.5) over silver-palladiumplatinum-glass frit. (Special order, added cost)
S = Tin-lead (63/37) over silver-palladium-platinum-glass frit. (Special order, added cost)
R = Matte tin over nickel over silver-platinum glass frit. (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.
Custom screening also available.
