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.
