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