Overtone crystal
Webwhere n is the overtone number and C is a constant that depends on the property of the crystal used. Equation 1, typically referred to as the Sauerbrey equation, constitutes the basic principle of QCM technology. 2 For a 5 MHz AT-cut quartz crystal at room temperature, C is approximately equal to 17.7 ng/ (cm 2 ·Hz). Weboscillation at the third-overtone. (See figure 1.) Tuning Tank LC Overtone Circuit • In an overtone mode, an additional inductor L1 and capacitance Cc is required to select the 3rd-Overtone mode, while suppressing or rejecting the fundamental mode. Choose Lc and c component values in the 3rd-overtone crystal circuit to satisfy
