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). |

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.
