Abstract

A rectangular AT-cut quartz resonator comprising a quartz crystal plate rotated about 35 DEG around the X-axis, has dimensional ratios w/t and l/t respectively in the range of 3.1 to 3.7 and 14.5 to 16.2, where the length l, width w and thickness t are respectively along the X-axis, Z-axis, and Y-axis.
