Technical Highlights

  • Zero mechanical hum or acoustic vibration — continuous strip has no stamped lamination burrs or loose gaps.
  • No-load exciting current is less than 10% of traditional EI transformers, with full-load temperature rise ≤ 35K.

Application Scenarios

  • High-end audiophile DACs, phono preamplifiers, headphone amplifiers, tube power amplifiers, and low-noise precision medical instruments.

Key Features

  • Continuous circular-cross-section core wound from premium Nippon Steel grain-oriented silicon strip.
  • Twin balanced bobbins provide 100% galvanic symmetry and extremely low inter-winding capacitive coupling (<15 pF).
  • Annealed OFC copper perimeter foil shield band virtually eliminates stray magnetic field radiation (<5 mG).
