When ordering, please specify packaging code: C1453-ALD Packaging: D = 13 ″ machine ready reel. EIA-481 embossed plastic tape (500 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 250 kHz, 0.3 Vrms. 3. Peak primary current drawn at minimum input voltage. 4. Leakage inductance is for the primary winding with the secondary wind- ings shorted. 5. Turns ratio is with the secondary windings connected in parallel. 6. Output of the secondary is with the windings connected in parallel. Bias winding output is 10 V. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
