Flyback Transformer

RoHS compliant AEC-Q flag
  • Developed for use with Silicon Labs Si88xx isolated dc-dc-converter reference designs.
  • Designed to meet basic insulation class with 3 mm creepage and clearance
  • Low leakage inductance at 60 nH
  • AEC-Q200 Grade 1 (−40°C to +125°C)
  • 2500 Vrms, one minute isolation (hipot), from primary to secondary. For a 5000 Vrms version, please see the TA7618-AL

  1. When ordering, please specify packaging code: e.g.TA7608-ALD
  2. Inductance is for the primary, measured on an Agilent/HP 4284 at 100 kHz, 0.1 Vrms, 0 Adc.
  3. DC current that causes an inductance drop of 30% (typ) from its value without current.
  4. DCR is measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  5. Leakage inductance measured between pins 2 and 3 at 100 kHz, 0.1Vrms, 0 Adc with pins 8 and 5 shorted.
  6. Isolation (hipot) measured between windings for one minute.


  • RoHS tin-silver-copper (95.5/3.8/0.7) over tin over nickel over phos bronze.


  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape (600 parts per full reel).
  • B = Less than full reel
