Voltage Coefficient of Resistance (VCR) is a measure of the stability of the resistor with respect to changes in voltage. Thick film resistors can exhibit significant VCR values. Low value chips may have a VCR of less than 10 ppm/V, while high value chips may change by 200 or 300 ppm/V or more. Thin film resistors have low VCR values regardless of size and resistance value, with a typical change in resistance of less than 2 ppm/V. Thick film resistors will satisfy all but precision or high voltage applications. Where VCR is critical, thin film resistors or SOTA's high voltage products can provide the desired performance.
