For Alcatel, Motorola
and TI chip sets
ADSL Transformers
This product is not RoHS-compliant. Contact Coilcraft
for current status or possible alternatives.
These transformers have been designed to provide opti-
mum performance with the ADSL chip sets from a variety
of leading manufacturers.
They feature a compact size, minimum DC resistance
and very low leakage inductance. Primary inductance is
stable from –40°C to +85°C and the longitudinal balance
is optimized for the best overall performance at the ADSL
transmission speed. Most parts have been designed to
meet UL 1950 requirements.
For free evaluation samples or to discuss custom designs,
please contact Coilcraft.
