When ordering, please specify tolerance, termination and packaging codes: e.g. 1812FS-105KLC |
|
Tolerance: |
J = 5%, K = 10% (Table above shows stock tolerances in bold.) |
|
|
Termination: |
L = RoHS compliant silver-palladium-platinum-glass frit
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 (600 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 (2200 parts per full reel). |

Inductance measured at 100 kHz, 0.1 Vrms, using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter
or equivalent. |
| 3 |
Tolerances in bold are stocked for immediate shipment. |
| 4 |
Q measured at 1 MHz using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture. |
| 5 |
DCR
measured on a micro-ohmmeter and a Coilcraft CCF840 test fixture. |
| 6 |
SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details |
| 7 |
Isat: DC current at
which the inductance drops 10% (typ.) from its value without current.
Details |
| 8 |
Irms: Current that causes a
40°C temperature rise from 25°C ambient.
Details |
| 9 |
Ambient temperature range: |
–40°C to +85°C with Irms current.
+85°C to +125°C with derated current. Derating curve |
| 10 |
Storage temperature range: |
Component: –40°C to +125°C
Packaging: –55°C to +80°C |
| 11 |
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. |
| 12 |
Electrical specifications at 25°C. |
| 13 |
Temperature coefficient of inductance (TCL): +200 to +700 ppm/°C.
