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.
