xDSLFilterModules
This product is not RoHS-compliant. Contact Coilcraft
for current status or possible alternatives.
By using Coilcraft’s tight-tolerance chip inductors mounted
on a SIP package, these filter modules offer superior
performance while occupying a fraction of the space of
conventional designs.
The 250 and 251 modules combine three functions on a
single space-saving unit: hybrid transformer, receive
filter and transmit filter for VDSL. The other modules are
high performance low pass and band pass filters for
various xDSL implementations.
Coilcraft can provide application-specific designs and
also makes available a library of reference designs for
those who wish to integrate filtering into their own board.
For free evaluation samples or more information, please
contact Coilcraft or visit www.coilcraft.com/xdsl.
