Defined as a ± percentage of the ideal in response to a change in temperature. Usually value, e.g. ± 5 %. defined in units of PPM/°C. For reference: ± 100 PPM/°C = 0.01 %/°C. Ratio Tolerance The permitted variation from the specified ratio TCR Tracking (Ratio TC) formed by two or more values within a resistor The expected change in the ratio formed by two network. Defined as a ± percentage of the ideal ratio, or more resistors in response to a change in e.g. ± 0.1 %. temperature. Usually defined in units of PPM/°C.
