| 1 | When ordering, please specify packaging code: e.g. C1495-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 250 kHz, 0.2 Vrms, 0 Adc | |
| 3 | Ipk is peak primary current drawn at minimum input voltage. | |
| 4 | DCR for the secondary is per winding | |
| 5 | Leakage inductance is measured between pins 3 and 4 with all other windings shorted. | |
| 6 | Turns ratio is with the secondary windings connected in parallel. | |
| 7 | Output of the secondary is with the windings connected in parallel. Bias winding output is 12 V, 20 mA. | |
| 8 | Ambient temperature range: | –40°C to +85°C |
| 9 | Storage temperature range: | Component: –40°C to +85°C T&R packaging: –40°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. | ||
