ADSLTransformers

These transformers have been designed to provide

optimum performance with the Alcatel Dynamite MTK-

20140, Analog Devices AD20MSP910 and Motorola

MC145660 and MS143462SK CopperGold^TMchip 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.
