Notes
  1. When ordering, please specify termination and testing codes: e.g. AR312FRA222MPZ.
  2. Frequency at which the differential mode attenuation equals −3 dB.
  3. Inductance measured at 100 MHz using an Agilent/HP 4286A impedance analyzer and a Coilcraft SMD-A fixture.
  4. DCR is specified per winding.
  5. Winding to winding isolation (hipot) tested for one minute.

Termination:

  • P = Tin-lead (63/37) over tin over nickel over silver-palladium-glass frit.
  • C  = Tin-lead (63/37) over gold over nickel over silver-palladium-glass frit
