EIA-481 embossed plastic tape (200 parts 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 150 kHz, 0.1 Vrms, 0 Adc. 3. Ipk is peak primary current drawn at minimum input voltage. 4. DCR for the primary is measured with windings connected in parallel. 5. Leakage inductance is for the primary, measured with secondary pins shorted. 6. Turns ratio is with the primary windings connected in parallel. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
