HDSL Transformers

This product is not RoHS-compliant. Contact Coilcraft

for current status or possible alternatives.

These HDSL transformers have been designed to work

with a variety of specific transceiver chips to provide

2B1Q coded data transmission.

They’re engineered for low leakage inductance and

return loss as well as high line isolation. Longitudinal

balance and THD are optimized for the best overall

performance at a given transmission speed.

Coilcraft can also custom engineer a transformer to

meet your specific requirements. For free evaluation

samples, contact Coilcraft or visit
