Notes

When ordering, please specify termination and testing codes: e.g. CP312FRA222MAZ.
Frequency at which the differential mode attenuation equals −3 dB.
Inductance is measured on an Agilent 4286A (or equivalent) with a Coilcraft SMD-A test fixture using the listed correlation.
Current per winding that causes a 20°C rise from 25°C ambient.
DCR is measured on a Keithley 580 Micro-ohmmeter (or equivalent) with a Coilcraft CCF858 test fixture.
Winding to winding isolation (hipot) tested for one minute.

Termination:

A = Gold over nickel over silver-palladium-glass frit.
C = Tin-lead over gold over nickel over silver-palladiumglass frit. (Special order, added cost)
F = Tin-silver-copper over gold over nickel over silverpalladium-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.
