Frequency specification of Quartz Crystal -- HC49U
20 Jan 2011The frequency of the quartz crystal is obviously a fundamental specification. It is normally expressed to as many significant figures as demanded by the frequency tolerance, although seven figures is normally the maximum. It is wise to express the frequency to the right number of significant figures to avoid misunderstandings in this area of the quartz crystal specification.
Kingtronica Quartz Crystal series are popular in the word market , Quartz Crystal include HC49U, HC49S and SMD quartz crystal HC49SMD .The HC49U is available in tight tolerances and stabilities for demanding applications. With a broad frequency range from 1.8432MHz to 200.000MHz, the HC49U can serve as a low cost solution in virtually any application or market.

About
Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
