| 1 | When ordering, please specify packaging code: e.g. D1766-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 200 kHz, 1.1 Vrms, 0 Adc | |
| 3 | Ipk: Peak primary current drawn at minimum input voltage. | |
| 4 | Leakage inductance is for the primary winding with the secondary windings shorted. | |
| 5 | All outputs are referenced to ground. | |
| 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. | ||
