EIA-481 embossed plastic tape (400 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 D instead. 2. Inductance is for the primary, measured at 375 kHz, 0.6 Vrms, 0 Adc. 3. Peak primary current drawn at minimum input voltage. 4. Leakage inductance is for the primary and is measured with secondary windings shorted. 5. Turns ratio is with the secondary windings connected in parallel. 7. Output of the secondary is with the windings connected in parallel. Bias winding output is 14 V. 8. Electrical specifications at 25°C.
