FREQUENCY TEMPERATURE CHARACTERISTIC CURVE
by curve
by calculation
Frequency deviation at one particular temperature (Tx) with
respect to the frequency at +25°C is
∆f/f (ppm) = -0.035 * (Tx – 25) ²
Example: at +60°C, the frequency drifts -42.8 ppm.
∆f /f (ppm) = -0.035*(60-25) ² = - 42.8 ppm
HOW TO ORDER
