ADSLTransformers
These transformers have been designed to provide
optimum performance with the Alcatel Dynamite MTK-
20140, Analog Devices AD20MSP910 and Motorola
MC145660 and MS143462SK CopperGoldTM chip sets.
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.
