SMT PoE Transformer
for NSC LM5071 and LM5072
- Developed for National Semiconductor LM5071 and LM5072 PD Controllers
- Designed to operate with an input voltage of 36 – 72 V
- Can accept 12 V input from auxiliary sources.
- 1500 Vrms isolation from primary to secondary
- Coilcraft's DA2257-AL and DA2383-AL are also specified by NSC for LM5071 & LM5072
- The FA2677-AL is specified by NSC for LM5072
- RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations

| 1 | When ordering, please specify packaging code: e.g. FA2519-ALD | |
| Packaging: |
D = 13" reel, machine-ready 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 200 kHz, 0.2 Vrms, 0 Adc | |
| 3 | Ipk is peak primary current drawn at minimum input voltage. | |
| 4 | Leakage inductance measured on the primary windings with all secondary pins shorted. | |
| 5 | Output for the secondary is with the windings connected in parallel. | |
| 5 | Ambient temperature range: | –40°C to +125°C |
| 6 | Storage temperature range: | Component: –40°C to +125°C T&R packaging: –40°C to +80°C |
| 7 | 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. | |
| 8 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
