Crystal stability
WebCrystal stability is defined in two ways: tolerance is the measure of frequency drift at room temperature, stability is the frequency drift over the rated temperature range. The nominal frequency is measured at +25°C. Then the frequency drift over temperature is reference as a ± ppm above and below the nominal frequency.
