Jensen Microphone Input Transformers

We are offering jensen microphone input transformers.
5 step-up for medium impedance amplifiers\rm optimum noise matching to many popular ic amplifiers\rm wide bandwidth: 3 db at 3 hz and 125 khz\rm 13.3 db of voltage gain with noise figure of only 2.5 db\rm input impedance of 1.5 k for loading loss of 0.9 db\rm high common-mode rejection: 118 db at 60 hz\rwith its 4.5 ks secondary source impedance, this transformer not only optimizes\rnoise performance of many ic or discrete amplifiers but also offers excellent\rcmrr as well. The primary is fully balanced and its leads may be reversed to\rinvert polarity, if required. A 30 db magnetic shield package is standard.
