| 1 | When ordering, please specify termination and packaging codes: e.g. D1803-ALC | |
| Termination: |
L = RoHS compliant matte tin 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 (750 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 (2500 parts per full reel). |
|
| 2 | Inductance measured at 100 kHz, 0.1 Vrms, using an Agilent/HP 4284 impedance analyzer or equivalent. | |
| 3 | DCR measured on a Keithley Instruments micro-ohmmeter or equivalent. | |
| 4 | SRF measured using an Agilent/HP 8753ES network analyzer. Details | |
| 5 | Isat: DC current at which inductance drops the specified amount from its value without current. Details | |
| 6 | Ambient temperature range: | –40°C to +125°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. | |
| 9 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
