DO1608 Inductors for xDSL Filters
These low cost, high inductance inductors are ideal
for use in a variety of filters, including the data separation
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
xDSL filters using these and other surface mount compo-
nents. We can also provide several complete low pass
and band pass filter modules in space-saving SIP con-
figurations.
