Split-3k Transformer: The Ideal Solution for Balanced/Unbalanced Conversion and R2R DACs

If you are looking for a high-quality audio transformer for your Hi-Fi system, the Split-3k transformer is the ideal solution for those seeking superior audio performance with maximum reliability. Designed to ensure balanced-to-unbalanced or vice versa conversion, this transformer is perfect for pairing with an R2R DAC circuit or other DAC chips delivering 5 Vpp signals and compatible with a maximum impedance of 3 k?.

Technical specifications:

  • Transformation ratio: 1:1
  • Primary impedance: 3 k? with center tap
  • Secondary impedance: 3 k? with center tap
  • DC resistance: about 1 k?
  • Primary inductance: about 48 H at 100 Hz
  • Frequency response (secondary loaded with 3.3 k? resistor):
    • 20 Hz –0.2 dB
    • 28 kHz –1 dB


Built with meticulous attention to detail and every technical parameter, the Split-3k transformer delivers excellent performance at both low and high frequencies, preserving crystal-clear audio quality. High inductance and low resistance guarantee clean, distortion-free transmission.
