CEPT

Matching Transformer

TEW5043

TEW5043 is specifically

designed to match a

The Return Loss exceeds the

requirements of

120 Ω twisted pair to a 75 Ω

coaxial line in the CEPT trunk.

CCITT G.703 and BS6328.

The Longitudinal balance

exceeds the requirements of

CCITT I.431.

DO NOT USE IN NEW

DESIGNS.

Use TEW5054 where

possible.
