When ordering, please specify a packaging code: A0009-AL D Packaging: D =1 3″ machine ready reel. EIA-481 embossed plastic tape (150 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 measured at 100 kHz, 0.1 Vrms, 0 Adc. 3. Leakage inductance measured at 100 kHz, 0.1 Vrms from pins 1 to 4 with all other pins shorted. 4. Isolation measured from pin 1 to pins 5 and 6; from 2 to 5 and 6; and from pins 1, 2, 5 and 6 to the core. 5. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. This surface mount flyback transformer is designed for use with National Semiconductor LM5000 DC/DC regu- lator. The core completely encloses the windings to minimize EMI interference. The transformer features very low DCR, 500 V isolation and a leakage inductance rating of just 1.0 µH. Coilcraft can also custom engineer a transformer to meet your specific requirements. For free evaluation samples, contact Coilcraft or order them on-line at www.coilcraft.com.
