The VSR series of resistors is a low cost version of the well established S series of resistors. These resistors are made of foil elements so all of the inherent performance of foil is retained. They do not however, have the same TCR or tolerance ranges. These products find a wide range of usage in high end stereo equipment and some grades of test and measurement equipment.
Standoffs are dimensioned to provide a minimum lead clearance of 0.010" between the resistor body and the printed circuit board, when the standoffs are seated on the board. This allows for proper cleaning after the soldering process.
Temperature coefficient of resistance (TCR) (1):
± 4 ppm/°C (0°C to + 60°C)
± 8 ppm/°C (- 55°C to + 125°C, + 25°C ref.)
Resistance range: 0.5 Ω to 1 MΩ (higher or lower values of resistance are available)
Vishay Foil resistors are not restricted to standard values
Tolerance: to ± 0.01 % (100 ppm)
Load life stability: to ± 0.005 % at 70°C, 2000 h at rated power
