JT-11K8-APC transformer is designed to optimize performance of low voltage noise, eN, amplifiers. It is recommended only for use with FET amplifiers with no significant current noise, iN. The primary is fully balanced and its terminals may be reversed to invert polarity, if required. A 30dB magnetic shield package is standard.
