SMT Data Line EMI Filters
–
TTDLF
We now offer an even more economical
version of this series: PDLF.
The PDLF is electrically identical and fits the same
land pattern. For the TTDLF 10000, please consider
our CCDLF10000. We will, however, continue to pro-
duce the TTDLF series indefinitely.
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 (300Vrms), environmental stability
and low cost.
These data line EMI filters come in 10, 8, 4, 3 and 2-line
versions with DC current capacity of 500 or 100 mA.
