VAR (Vishay Audio Resistor)
Vishay Foil Resistors
Ultra High Precision, High Resolution Z-Foil Audio Resistor,
with TCR of ± 0.2 ppm/°C, Tolerance to ± 0.01 %
and Noise < - 40 dB
Any value at any tolerance available within resistance range
INTRODUCTION
The VAR, composed of Vishay’s Bulk Metal® Z-foil
technology, with improved sound quality, provides a
combination of low noise and low inductance/capacitance,
making it unrivalled for applications requiring low noise and
distortion-free properties.
While the regular foil resistors are already widely
acknowledged as the leading resistors for audio applications,
the special “naked Z-foil resistor” design without mold or
encapsulation, adds an additional dimension for reducing
signal distortion and increasing clarity in signal processing.
Our application engineering department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
contact us.
