When ordering, please
specify termination and packaging codes. e.g. DO3314-333MLC |
|
|
Termination: |
L = Silver-palladium-platinum-glass frit terminations
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"
machine-ready reel
EIA-481 embossed plastic tape (1000 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"
machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked (3500 per
full reel). |

Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent. |
| 3 |
DCR measured on a micro-ohmmeter. |
| 4 |
SRF measured using
an Agilent/HP 4191A or equivalent. Details |
| 5 |
Isat: DC current at
which the inductance drops 10% (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: –405°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. |
| 10 |
Electrical specifications at 25°C. |
