Properties of miniature X- and Z′-elongated rectangular at-cut quartz resonators of different sizes

In this study, we present the different properties of beveling process, equivalent series resistance (ESR), temperature curves, temperature hysteresis, and shock resistance of different sizes of X- and Z'-elongated rectangular AT-cut quartz plates. The results show the Z'-elongated quartz strip mounted on the two width sides has better performance in temperature hysteresis and shock resistance. And for mode coupling, beveling process, and temperature curve, X- and Z'-elongated rectangular AT-cut quartz plate have their respective properties.
