When ordering, please specify packaging code: FA2636-ALD Packaging: D =1 3″ machine-ready reel. EIA-481 embossed plastic tape (175 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. The FA2636-AL surface mount flyback transformer was developed specifically for the National Semiconductor LM5001 High Voltage Switch Mode regulator for iso- lated and non-isolated flyback topologies. It is designed to operate in continuous mode at 250 kHz with an input voltage of 16 – 36 Volts. This industry- standard size EP13 transformer features 1500 Vrms isolation from the primary and auxiliary winding to the secondary. Output of the auxiliary winding is 7.5 V used to power the IC. Coilcraft can also custom design transformers with voltage, inductance and DCR values to meet your specific requirements.

Ipk is peak primary current drawn at minimum input voltage. 4. DCR for the secondary is per winding. 5. Leakage inductance measured between pins 3 and 2 with all other pins shorted. 6. Turns ratio is with the secondary windings connected in parallel. 7. Operating temperature range –40°C to +85°C. 8. Electrical specifications at 25°C. 0.061 1,55 0.500 12,70 0.530 13,46 0.039 1,00 0.512 13,00 0.699 17,75max 0.590 14,99 0.028 0,70 0.050 1,27 0.098 2,50 0.098 2,50 max max Recommended Land Pattern 0.004 /0,10 Dot above pin1 Weight: 6.28 g Terminations: Tin-silver over tin over nickel over phos bronze Tape and reel: 175/13″ reel 32 mm tape width Secondary windings to be connected in parallel on the PC board.
