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.

Termination:

  • RoHS-compliant. 260°C compatible.
    Planar transformers: Matte tin over nickel over brass terminations
    MSS6132: Gold over nickel over phos bronze terminations
    Output choke inductors - Tin-silver over tin over nickel over phos bronze terminations

Packaging:

  • C = 7" machine-ready reel
    EIA RS-481 clear plastic tape (350 parts per full reel).
  • D = 13" machine-ready reel
    EIA RS-481 clear plastic tape (Tranformer: 250 parts per full reel, Input Choke Inductor: 350 parts per full reel, Output Choke Inductor: 200 parts per full reel).
  • B = Less than full reel
    In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter C or D instead.
