Notes
  1. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms.
  2. DCR for the primary is measured with the windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  3. Leakage inductance is for the primary winding, measured at 100 kHz, 0.1 Vrms with the secondary winding shorted.
  4. 2000 Vrms, one minute isolation from primary and auxiliary to secondary windings.

Termination:

  • RoHS-compliant. Tin-silver over tin over copper over steel termination. Other terminations available at additional cost.

Soldering/Washing

Moisture Sensitivity Level (MSL):
1 (unlimited floor life at <30°C / 85% relative humidity)
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.
PCB Washing:
Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
