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.
