On the basis of the classical theory of thickness vibrations, the formulas for the temperature coefficients and their angular derivatives of the frequency-temperature characteristics of quartz resonators with LC-cut are derived. Approximation of these characteristics by straight lines enables the evaluation of nonlinearity effects in a given range of temperature. A practical example is given.
