WebAug 12, 2024 · This is primarily determined by the internal equivalent series resistance (ESR) of the crystal. The crystal you mentioned specifies ESR=50k. The resistance also increases over age (as moisture/impurties leak into the crystal case) and is also affected by soldering temperature/time. WebMay 27, 2024 · Therefore, the ESR value of a quartz crystal is an important value to consider during the design stage. If for example the ESR value is too high, the oscillator circuit may not have enough gain to overcome the crystal losses and may fail to start.
