| 1 | When ordering, please specify packaging code: e.g. C1048-ALD | |
| Packaging: | D = 13"
machine-ready reel EIA 481 embossed plastic tape (200 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 250 kHz, 0.3 Vrms, 0 Adc | |
| 3 | Ipk: Peak primary current drawn at minimum input voltage. | |
| 4 | DCR is for both windings of the secondary connected in parallel. | |
| 5 | Leakage inductance is for the primary winding with the secondary winding shorted. | |
| 6 | Output is with the the secondary windings connected in parallel. Bias winding output is 15 V, 0.2 A. | |
| 7 | Ambient temperature range: | –40°C to +125°C |
| 8 | Storage temperature range: | Component: –40°C to +125°C Tape and reel packaging: –40°C to +80°C |
| 9 | 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. | |
| 10 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
