For Alcatel, Motorola
ADSLTransformers and TI chip sets
This product is not RoHS-compliant. Contact Coilcraft
for current status or possible alternatives.
These transformers have been designed to provide
optimum 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 de-
signed to meet UL 1950 requirements.
For free evaluation samples or to discuss custom de-
signs, please contact Coilcraft.
