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
produce the TTDLF series indefinitely.
Coilcraft surface mount filters are designed to virtually
eliminate the problem of conducted EMI in data line
applications. They provide exceptional common mode
noiseattenuationfrom15MHzto300MHzwhilepassing
signallinedatabelow300MHzwithminimalattenuation.
These low resistance filters have been designed for
excellent electrical isolation (300 Vrms), 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.
