SMT PoE Transformer for
National Semiconductor LM5020

New RoHS part numbers are shown. Lead was removed from terminations. The second to the last character is now L to indicate RoHS compliance. (View old data sheet.)
  • Flyback transformer developed for NSC LM5020 PWM Controller
  • Designed for 13 Watt IEEE 802.3af-compliant PoE applications
  • 36 – 72 V input, 3.3 V, 4.5 A output (with secondary windings connected in parallel)
  • 12 V Bias output
  • 1 MHz operating frequency
  • Low profile, surface mount
  • RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations

1 When ordering, please specify packaging code: e.g. B0695-ALD
Packaging: D = 13" 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.
2 Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc
3 Ipk is the peak primary current drawn at minimum input voltage.
4 Leakage inductance measured between pins 4 and 6 with all other pins shorted.
5 Turns ratio is with the secondary windings connected in parallel.
6 Capacitance measured between pins 3 and 4 with all other pins shorted.
7

Isolation is measured from the primary and bias windings to the secondary.

8 Ambient temperature range: –40°C to +85°C
9 Storage temperature range: Component: –40°C to +85°C
Packaging: –55°C to +80°C
10 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
11 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
