| 1 | When ordering, please specify termination and packaging codes: e.g. SLC1049-151MLC | |
| Termination: |
L = RoHS compliant matte tin over nickel over copper Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or 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, using an Agilent/HP 4263B LCR meter or equivalent. | |
| 3 | DCR measured at 25°C on a micro-ohmmeter at the points indicated in this diagram. | |
| 4 | SRF measured using an Agilent/HP 4191A network analyzer. Details | |
| 5 | Isat: DC current at 25°C that causes a 20% (typ) inductance drop from its value without current. Temperature derating curves. |
|
| 6 | Irms: Current that causes 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves. | |
| 7 | Ambient temperature range: | −40°C to +85°C with Irms Derating curves |
| 8 | Storage temperature range: | Component: −40°C to +125°C Tape and reel packaging: −40°C to +80°C |
| 9 | Maximum part temperature: +125°C (Ambient + temperature rise) | |
| 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. | ||
| PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info. | ||
