Notes
- When ordering, please specify termination and testing codes: e.g. ST458RFW04C1LZ.
- 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.
Termination:
- L = Tin-silver-copper (95.5/4/0.5) over silver-platinum-glass frit.
- S = Tin-lead (63/37). (Special order,added cost)
Testing:
