VSR144 VSR144 Vishay Foil Resistors Bulk Metal® Foil Technology Industrial Grade Miniature Voltage Divider FEATURES · Temperature Coefficient of Resistance: Nominal TCR: ± 4ppm/°C (0° to 60°C) · TCR Tracking: 1.5ppm/°C Product may not be to scale · Ratio Stability: < ± 0.001% (10ppm) under load-life conditions The VSR144 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.

For resistance ratios not shown, contact Vishay's Applications Engineering Department. The VSR144 VSR144 can be made available in any required ratio between the resistance values of 100 ohms and 20Kohms, such that R1 can be any value between 100 ohms and 20Kohms and R2 can also be any value between 100 ohms and 20Kohms. New art work is required. 2. Power is proportional to the divider ratio. Example: In a VSR144 VSR144 (1K/10K 1K/10K dual), the power rating would be 18mW on the 1K and 182mW on the 10K, for a total of 200 mW on R1 + R2. R1 R2 P1 = P P2 = P R1 + R2 R1 + R2 ( ) ( ) 3. Maximum working voltage is 200 Volts.
