Web1) Crystal thickness The fundamental frequency is inversely proportional to the thickness, h, of the crystal disk, eq. (1). The higher the fundamental frequency, the thinner the crystal. For example, a 5 MHz QCM crystal will have a thickness of ~334 um, and a 10 MHz crystal will be half that, and have a thickness of ~167 um.
