Notes

When ordering, please specify screening code: e.g. AR458RFW04C1SZ.
Inductance measured at 100 kHz, 0.1 V, 0 Adc on an Agilent/HP 4192 or equivalent.
DCR measured on a micro-ohmmeter.
Impedance ratio is for the full primary winding to the full secondary winding.
DC imbalance is the maximum difference in current measured at pins 4 and 6 with the source at pin 5. Inductance drop is 15% at maximum imbalance.

Screening:

Z = Unscreened
H = Group A screening per Coilcraft CP-SA-10001
2 = EEE-INST-002 level 2
3 = EEE-INST-002 level 3
4 = MIL-STD-981 Class B
5 = MIL-STD-981 Class S
F = Screening per ESCC 3201
All screening performed to the document’s latest revision Custom screening also available
Note: Screening T and U have been replaced with more detailed codes 4, 5, and 1, 2, 3, respectively. Codes T and U can still be used, if necessary.
