Document 222-1 Document 222-1 Revised 11/20/10 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. 1. All electrical specifications referenced to line side. 2. Operating temperature range -40°C to +85°C. 3. Electrical specifications at 25°C.
