Temperature coefficient of resistance (TCR) is the calculation of a relative change of resistance per degree of temperature change. It is measured in ppm/°C (1 ppm = 0.0001%) and is defined as: TCR = (R2– R1)/ R1 (T2– T1). For high-precision resistors, this specification is typically expressed in parts per million (ppm) per degrees ...
