Different expansion/contraction rates of composite materials in resistors may induce discontinuities during temperature excursions that are not evident at temperature extremes, making an unreliable resistor appear normal. A good resistor must also return to its initial value with no resistance drift. In this demo, a VFR VSMP0805 precision resistor is monitored through the range of +25⁰C, down to -200⁰C and back up to +25⁰C. Results confirm the VSMP0805 exhibits only 5ppm/⁰C TCR, experiences no discontinuities, and returns to its exact same starting value.
