| 1 | When ordering, please specify termination and packaging codes: e.g. DA2317-ALC | |
| Termination: |
L = RoHS compliant tin-silver over tin over nickel over phos bronze Special order, added cost: S = non-RoHS tin-lead (63/37) |
|
| Packaging: |
C = 7" reel, machine-ready EIA-481 embossed plastic tape (250 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 C instead. D = 13" reel, machine-ready EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel). |
|
| 2 | Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc | |
| 3 | Leakage inductance measured at 100 kHz, 0.1 Vrms with secondary pins shorted. | |
| 4 | DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator. | |
| 5 | SRF measured with coils connected in series using an Agilent/HP 4192 or equivalent. | |
| 6 | Ambient temperature range: | −40°C to +125°C |
| 7 | Storage temperature range: | Component: −40°C to +125°C Tape and reel 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. | ||
| PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info. | ||
