Modified Transformers Most Jensen transformers are available with slight modifications such as different part numbers, different lead types or extra shielding cans at a modest extra cost. Please keep in mind that special requirements will result in longer lead times as modified transformers will need to be made to order. Contact our sales department for more information.

Custom Transformers The unique combination of features embodied in Jensen Transformers can provide solutions for seemingly "impossible" problems. Their high Common Mode Rejection Ratio, extended Low Frequency Response and Extremely Low Distortion make them a perfect choice as interfaces for many specialized test and measurement instruments such as:

Audio Precision® - System One and System Two Output Transformers Jensen Transformers manufactures the output transformers used in these "State of the Art" audio measurement systems. Developed to function in Audio Precision's patented distortion cancelling output drive circuit, these transformers provide high output level at vanishingly low distortion.

Stanford Research Systems - Model SR554 Low Noise Preamplifier Jensen Transformers worked closely with SRS to develop a 1:100 step-up ratio transformer with an Extremely low noise voltage of 0.1nV per root Hertz for use with low impedance transducers with very low signal levels. The Common Mode Rejection Ratio of this transformer is over 120dB at 60Hz and the Frequency Response extends from 40kHz down to an amazing 0.1Hz!

Specifying a Custom Transformer When inquiring about a custom application, you will need to provide us with certain basic information. This will help us do the best possible job designing your product. Custom Transformer Basic Specifications: 1) Driving Source Impedance 2) Transformer Secondary Load Impedance 3) Low Frequency Requirements 4) High Frequency Requirements 5) Maximum Low Frequency Input Level 6) Nominal Reference Level 7) Maximum Allowable Low Frequency Distortion The more information that you can provide, the better that we can determine the optimum design for your application. We can help you in determining some of the above parameters if you are not certain of them. We can also help with modifications to your interface circuit design in order to optimize it's performance when used with one of our transformers.
