Manufacturer's QC certification sheet for this lot adds the following information:
Al value: 6344  nH / T^2   +/- 25%,
average of 9 samples from the lot, taken with an Agilent 4275A LCR Analyzer,
Turn count = 1, Freq = 100KHz
Note: Depending on construction, a 40mm size transformer can produce 400-900W max power in an SMPS application.  Maximizing factors will include a full bridge topology, 100KHz+ operating frequency, and use of triple-insulated winding wire to optimize transformer performance.
