| 1 | When ordering, please specify termination and packaging codes: e.g. DW3316-685MLD | |
| Termination: | L = Gold over nickel over phos bronze Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). |
|
| Packaging: | D = 13" reel, machine-ready EIA-481 embossed plastic tape (750 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. |
|
| 2 | Inductance is per winding, tested at 10 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent. | |
| 3 | DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator. | |
| 4 | SRF measured using Agilent/HP 8753D network analyzer. | |
| 5 | Isat: DC current at which the inductance drops 10% (typ.) from its value without current. | |
| 6 | Ambient temperature range: | −40°C to +85°C |
| 7 | Storage temperature range: | Component: −40°C to +85°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. | ||
