Notes
  1. Inductance measured at 10 kHz, 0.1 Vrms, 0 Adc.
  2. Leakage inductance measured across the primary at 100 kHz, 0.1 Vrms, 0 Adc.
  3. Isolation tested between primary and secondary and between auxiliary and secondary windings.
  4. Inductance measured at 10 kHz, 0.1 Vrms.
  5. DCR is per winding measured at 25°C. For other temperatures, use this DCR at Temperature calculator.
  6. Isat: current at which inductance drops 10% (typ) from its values without current.
  7. Irms: Current that causes the specified temperature rise from 25°C ambient. Details

Soldering

Resistance to soldering heat:
Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
Refer to Soldering Coilcraft Components before soldering.
