| 1 | When ordering, please specify packaging code: e.g. HA3648-BLD | |
| 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 measured on an Agilent/HP 4284 across the primary at 250 kHz, 0.1 Vrms, 0 Adc. | |
| 3 | Leakage inductance is for the primary, measured at 250 kHz, 0.1 Vrms, 0 Adc with secondary winding shorted. | |
| 4 | DCR for the secondary is across both windings (from pin 6 to pin 10). | |
| 5 | Ambient temperature range: | –40°C to +85°C |
| 6 | Storage temperature range: | Component: –40°C to +85°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. | ||
