Notes
  1. When ordering, please specify packaging code: e.g. UA7868-AEC
  2. Inductance is for the primary (L1), measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
  5. Isat: DC current applied to L1 at which the inductance drops 10% (typ) from its value without current.

Termination:

  • RoHS compliant silver-palladium-platinum-glass frit.

Packaging:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape 1000 parts per full reel).
  • B = Less than full reel
    In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead.
  • D = 13" machine-ready reel
    EIA-481 embossed plastic tape. Factory order only, not stocked (3500 parts per full reel).
