DO1608 Inductors for xDSL Filters
These low cost, high inductance inductors are ideal
for useinavarietyoffilters,includingthedataseparation
filters used in ADSL, VDSL and ISDN/ADSL implemen-
tations.
Their wirewound design and ferrite core provide high Q
factors, low DCR and high current handling.
Coilcraft offers a library of reference designs for various
xDSLfiltersusingtheseandothersurfacemountcompo-
nents. We can also provide several complete low pass
and band pass filter modules in space-saving SIP con-
figurations.
Coilcraft Designer’s Kit C377 contains three samples
