Ultra-Fine 0.03mm x 4000 Strands Natural Silk Covered Litz Wire
Premium choice for high-fidelity audio applications where conductor quality affects frequency response, transient speed, and harmonic integrity. Our specialized Litz wire is designed for audio enthusiasts, sound engineers, and high-end audio equipment manufacturers.
Superior Performance in Voice Coils and Speaker Drivers
The multi-strand Litz design ensures all frequencies encounter consistent resistance, yielding a flatter impedance curve and less phase shift. The 0.03mm ultra-fine strands provide extraordinary transient response, enabling voice coils to start and stop instantly for percussive attacks and vocal sibilance with breathtaking clarity.
Beyond Voice Coils - Interconnects and Headphone Cables
Ideal as a signal conductor in analog audio interconnects and headphone cables. Low capacitance maintains high-frequency extension while silk insulation reduces triboelectric noise. Litz construction minimizes eddy currents that can smear imaging and reduce soundstage depth.
Customization Options
- Single conductor diameter: 0.025mm to 0.5mm
- Thermal ratings: 155°C (Class F), 180°C (Class H), or 220°C (Class C)
- Strand count: 1 to 12,700 strands
