Quartz Crystal also known as Quartz Crystal Oscillator. That was accomplished by means of "Piezoelectric" effect.
That is "Supply Voltage", Kingtronics common voltages are 1.8V, 3.3V, 5.0V.
The semiconductor devices and resistance capacitance element worked together, could constitute a Quartz Crystal Oscillator. 

Quartz Crystal Applications:
1, QKT-HC49U (HC-49U) suitable for electronic products with broad spaces such as communications equipment, televisions, telephones, electronic toys;
2, QKT-HC49U/S (HC-49U/S) is suitable for all kinds of space height restrictions thin and small electronic equipment and products;
3, QKT-HC49 SMD (HC-49U/S SMD) prevail surface mount products, applicable to all types of ultra-thin, small computers and electronic devices;
4, 3*8 Tuning fork Cylindrical quartz crystal resonators suitable for space-constrained timing frequency stabilization of electronic products such as timers, electronic clock, calculator, etc.

Kingtronics offers passive leaded quartz crystal HC49UHC49S, SMD quartz crystal HC49SMD

You can vist below link to find more information about our Crystals:

Limited resources of natural quartz crystal suitable for direct electronic or optical use are available throughout the world. World dependence on these resources will continue to decline because of the increased acceptance of cultured quartz crystal as an alternative material; however, use of cultured quartz crystal will mean an increased dependence on lascas for growing cultured quartz.

Trends indicate that demand for quartz crystal devices should continue to grow, and consequently, quartz crystal production should remain strong well into the future. Growth of the consumer electronics market (for products such as personal computers, electronic games, and cellular telephones) will continue to drive global production. The growing global electronics market may require additional production capacity worldwide.

In the past several years, cultured quartz crystal was increasingly produced in the world, primarily in Asia. Electronic applications accounted for most industrial uses of quartz crystal; other uses included special optical applications.Virtually all quartz crystal used for electronics was cultured rather than natural crystal. Electronic-grade quartz crystal was essential for making filters, frequency controls, and timers in electronic circuits employed for a wide range of products, such as communications equipment, computers, and many consumer goods, such as electronic games and television receivers.

Quartz crystal is the best material for frequency-control oscillators and frequency filters in electronic circuits.

Kingtronics offers leaded quartz crystal HC49UHC49S and SMD quartz crystal HC49SMD.If you want more details ,please visit website www.kingtronics.com for full specification.

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.
