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) FEATURES • Temperature Coefficient of Resistance (TCR): Absolute: ± 4 ppm/°C (0 °C to + 60 °C) ± 8 ppm/°C (- 55 °C to + 125 °C, + 25 °C Ref.) Tracking: 1.5 ppm/°C Pb-free Available RoHS* COMPLIANT • Tolerance: Absolute and Matching to ± 0.02 % 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.

ABSOLUTE AVAILABLE TO TCR TRACKING AVAILABLE TO RATIO MATCH AVAILABLE TO ± 0.02 % < ± 1.5 ppm/°C For Like Values ± 0.02 % < ± 2.0 ppm/°C Standard Notes 1. Power is proportional to the divider ratio. Example: In a VSR144 (1K/10K dual), the power rating would be 18 mW on the 1K and 182 mW on the 10K, for a total of 200 mW on R1 + R2.
