Notes
  1. When ordering, please specify packaging code: e.g. B0310-ALD
  2. Inductance measured between pins 1 and 3 at 250 kHz, 0.1 Vrms, 0 Adc
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. When ordering, please specify packaging code: e.g. MSS6132-103MLC or B0414-ALD
  5. Input Choke: Inductance measured at 100 kHz, 0.1 Vrms.
    Output Choke: Inductance measured at 10.0 kHz, 0.1 Vrms.
  6. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  7. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD-D test fixture. Details
  8. Isolation measured from pin 5 to pins 1, 2, 3, 4.
  9. Input Choke: DC current at which the inductance drops 10% (typ) from its value without current. Details
    Output Choke: DC current at which the inductance drops 12% (typ) from its value without current. Details
  10. Input Choke: Current that causes the specified temperature rise from 25˚C ambient. Details
    Output Choke: Current that causes a 40˚C temperature rise above 25˚C ambient. Details

Termination:

  • RoHS-compliant. 260°C compatible.
    Planar transformers: Matte tin over nickel over brass terminations

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.
