| 1 | When ordering, please specify packaging code: e.g. GA3550-BLD | |
| Packaging: |
D = 13" reel, machine-ready 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 each winding measured at 200 kHz, 0.4 Vrms, 0 Adc. | |
| 3 | Leakage inductance is for the primary, measured at 200 kHz, 0.4 Vrms with the secondary winding shorted. | |
| 4 | Volt-time product is per winding. | |
| 5 | SRF is per winding, measured on an Agilent/HP 4192 or equivalent. | |
| 6 | Ambient temperature range: | –40°C to +85°C |
| 7 | Storage temperature range: | Component: –40°C to +85°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. | |
| 8 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
