When
ordering, please specify termination and packaging codes: e.g.
LPR6235-253PMLC |
|
|
Termination: |
L = 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 350 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" machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked (1500 parts
per full reel). |

Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. |
|
3 |
SRF measured using an Agilent/HP 4191A or equivalent. |
|

Isat:
DC current applied to L1 at which the inductance drops 10% from its value without current. |
| 5 |
Ambient temperature range: |
–40°C to +125°C |
| 6 |
Resistance to soldering heat: Three reflows at >217°C for 90seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. |
| 7 |
Electrical specifications at 25°C. |
| Refer to Soldering Coilcraft Components before soldering. |
