VSR144_07 Datasheet, PDF (1/4 Pages) Vishay Siliconix – Bulk Metal Foil Technology Industrial Grade Miniature Voltage Divider

VSR144
Vishay Foil Resistors
Bulk Metal^® Foil Technology Industrial Grade
Miniature Voltage Divider with TCR Tracking of
1.5 ppm/°C and Ratio Stability of 0.001 % (10 ppm)
Any value at any ratio available within resistance range
The VSR144 is an industrial version of the 300144. This
device has the stability that is inherent in foil but does not
offer the tight match, TCR, or TCR tracking of the 300144.
This product is quite satisfactory for most industrial purposes
and should be considered when the total performance of the
300144 is not necessary.
