1. Inductance measured at 100 kHz, 0.1 V, 0 Adc using an Agilent/
HP 4284A impedance analyzer or equivalent.
2. DCR measured on Cambridge Technology micro-ohmmeter.
3. Leakage inductance is for the primary and measured with pins 4 and 8
shorted.
4. Current that causes a 40ºC temperature rise from 25°C ambient.
5. Electrical specifications at 25°C.
