| 1 | When ordering, please specify packaging code: e.g. DA2420-ALD |  Primary windings to be connected in parallel on the PC board. |
|
| 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 100 kHz, 0.1 Vrms, 0 Adc | ||
| 3 | Ipk is peak primary current drawn at minimum input voltage. | ||
| 4 | Leakage inductance measured on the primary windings with secondary pins shorted. | ||
| 5 | Turns ratio is with the primary windings connected in parallel. | |
| 6 | Ambient temperature range: | –40°C to +125°C |
| 7 | Storage temperature range: | Component: –40°C to +125°C T&R packaging: –40°C to +80°C |
| 8 | 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. | |
| 9 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
