Product Description
AT Cut Quartz Blanks Used In Oscillators To Microbalances
AT-cut quartz crystals are widely used in applications ranging from oscillators to microbalances. An important characteristic of AT-cut quartz crystals is that the resonant frequency of such crystals is independent of the first-order temperature, which is desirable for mass sensing and timing applications. AT cut crystals vibrate in thickness shear mode - the applied voltage on the cutting surface generates shear stress inside the crystal. In this example, the vibration of the AT cut thickness shear oscillator is analyzed, with emphasis on the mechanical response of the system in the frequency domain. The effect of series capacitors on mechanical resonance is also analyzed. Adding series capacitors is a common technique for tuning crystal oscillators.

FAQs:
- Q: What are the products you mainly work on?
A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.
- Q: Can you accept product customization?
A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
Acceptance Check
