ADSL TRANSFORMERS FOR
ALCATEL,MOTOROLA AND TI CHIP SETS |
|
|
|
|
|
|
|
|
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.minimun DC resistance and very low leakage inductance.Primary
inductance is stable from -40°C to +85°C and the longitudinal
blance 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. |
