| 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). |

Inductance measured at 100 kHz, 0.1 Vrms, using an Agilent/HP 4263B LCR meter or equivalent. |
| 3 |
DCR measured on a
micro-ohmmeter. Connection points for measuring
DCR |
| 4 |
SRF measured using
an Agilent/HP 4191A network analyzer.

| 5 |
Isat: DC current at which
inductance drops 20% (typ) from its value without current.
Details |
| 6 |
Irms: Current that causes a 40°C temperature rise from 25°C ambient.
Details |
| 7 |
Ambient temperature range: |
–40°C to +85°C with
Irms current.
+85°C to +125°C with derated current Derating curve |
| 8 |
Storage temperature range: |
Component: –40°C to +125°C
Packaging: –55°C to +80°C |
| 9 |
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. |
