SMT Data Line EMI Filters – TTDLF
As of August 2015, the TTDLF 10000 is no longer
available; please consider our CCDLF 10000.
For the TTDLF 2x000, TTDLF 3x000 and
TTDLF 4x000, we now offer an even more economi-
cal version of this series: PDLF. The PDLF series is
electrically identical and fits the same land pattern.
Coilcraft surface mount filters are designed to virtually
eliminate the problem of conducted EMI in data line ap-
plications. They provide exceptional common mode noise
attenuation from 15 MHz to 300 MHz while passing signal
line data below 300 MHz with minimal attenuation.
These low resistance filters have been designed for excel-
lent electrical isolation (300 Vrms), environmental stability
and low cost.

1. When ordering, please specify termination and packaging codes:
TTDLF 2500LD
Termination: L = RoHS compliant tin-silver-copper over silver-
platinum-glass frit.
Special order: S = non-RoHS tinlead (63/37).
Packaging: C = 7″ machine ready reel. EIA-481 embossed plastic
tape (500 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 D instead.
D = 13″ machine ready reel. EIA-481 embossed plastic
tape (2200 parts per full reel).
2. Current rating is for each line.
3. Inductance is per winding, tested at 1 MHz.
4. Operating temperature range -40°C to +85°C.
5. Electrical specifications at 25°C.
