Jensen Transformers JT-16-A 1:2 Microphone Step-Up Transformer

JT-16-A is Jensen Transformer's highest-performance microphone input transformer, making it perfect for ultra-low noise amplifiers.

Legendary for their sonic transparency, Jensen mic input transformers feature internal Faraday shielding virtually eliminating hum, buzz, and RF interference, while MuMETAL® magnetic shielding enclosures reduce hum caused by nearby magnetic fields. Extended low-frequency and Bessel-tailored high-frequency responses result in the ultra-low time-domain distortion (DLP) that only Jensen offers. Insertion loss is minimal and adding phantom power is simple.

Here are some key specs:

  • Jensen Transformer's highest-performance mic input transformer
  • Impedance ratio: 150:600
  • Turns ratio: 1:2
  • Maximum 20 Hz input: +10 dBu
  • THD @ 20 Hz: 0.025 %
  • Frequency Response: 20 - 20 KHz,  -0.06 / -0.00 dB
  • See spec sheet for additional details

Jensen Transformers' Description

Jensen Transformers JT-16-A



  • Our highest performance mic input transformer
  • Wide bandwidth: -3 dB at 0.45 Hz and 220 kHz
  • Excellent time domain performance: DLP +1° typical
  • Transformer related Noise Figure only 1.7 dB
  • High common-mode rejection: 117 dB at 60 Hz

With its 4.1 kΩ secondary source impedance, this transformer not only optimizes noise performance of many IC or discrete amplifiers but also offers excellent CMRR as well. The primary is fully balanced and its leads may be reversed to invert polarity, if required. A 30 dB magnetic shield package is standard.
