4 Inch 0.35mm Double Side Polish Lithium Tantalate Wafer 36Y 42Y For SAW and BAW Applications
Lithium Tantalate (LiTaO3) is an ideal material for both SAW and optical use. It has relatively large electromechanical coupling coefficient and low acoustic attenuation. Typical cut angle for SAW application is 36°Y, 42°Y, X-cut etc. The Lithium Tantalate reduction technology makes the wafer “black” and free of pyroelectric discharge, which enables even higher frequency SAW application.
BonTek Optoelectronics is a professional manufacturer of LiNbO3 and LiTaO3. We can provide you the desired customization with best prices.

FAQs:
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.
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.
A: Yes, we would suggest you go with the courier agent you are most familiar with (DHL, FedEX, UPS etc.). We can ship via your account. And, of course, we will pack the products safely in acceptable size to help you save the shipping cost. If you need us to take care of the freight, it’s also not a problem. We also have good discount with the international courier companies.
A: The wafer products are fragile and sometimes expensive. The last thing, as the manufacturer, we want to see is the products we make were damaged during courier. As a result, we will pack the wafers adequately and put them in a proper carton filled with buffer sponge. However, accidents are inevitable sometimes. So, please follow the “Acceptance check” steps shown in the drawings below. If the unwanted happened, we will either give the replenishment or refund if you follow the checking steps.
