                    VPG Foil Resistors' ultra-high precision, Z-Foil audio resistor minimizes noise and distortion in the signal path
    

Image of VPG Foil Resistors' Z-Foil VAR VPG Foil Resistors has announced the expansion of its high-end audio application portfolio with the release of the enhanced ultra-high-precision Z-Foil VAR. Based on bulk metal foil technology, the new devices are specifically designed to minimize the self-inductance and capacitance inherent in all resistors, offering improvements in sound quality by reducing audible distortion. The devices are optimized for use in loudspeaker crossover assemblies, audio power amplifiers, and instrumentation amplifiers.

The company has enhanced the ultra-high-precision Z-Foil VAR resistor to offer low TCR down to 0.05 ppm/°C typical from 0°C to +60°C, 25°C ref, tolerances down to ±0.005%, and load-life stability to ±0.005% (50 ppm) at 70°C for 2,000 hours at rated power. The device has been bolstered with a thermal stabilization time of <1 s (nominal value achieved within 10 ppm of steady state value) and can operate at higher frequencies.

The VAR provides a combination of low noise, low inductance / capacitance, and improved thermal response, making it unrivalled for applications requiring distortion-free properties. Its special 'naked Z-foil resistor' design, without molding or encapsulation, adds an additional dimension for reducing signal distortion and increasing clarity in signal processing.
