1. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/
HP 4263B impedance analyzer or equivalent.
2. Peak primary current drawn at minimum input voltage.
3. Leakage inductance is for the primary and is measured with the second-
ary shorted.
4. Output of the P1 winding is 10 V, 20 mA.
5. Isolation:  3000 Vrms, one minute primary to secondary;
500 Vrms, one minute windings to core
6. Electrical specifications at 25°C.
