Crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. The most common type of piezoelectric resonator used is the quartz crystal, so oscillator circuits incorporating them became known as crystal oscillators.

Quartz crystals most are used for consumer devices, inside test and measurement equipment, such as wristwatches, clocks, radios, computers, cellphones, counters, signal generators, and oscilloscopes.

Kingtronics produce below Quartz Crystals and Oscillators, with good price and quality. Welcome check our product link and send your inquiry to us!

•Good shock measures to ensure the Quartz Crystal don’t fall to the ground during use.

• When storing crystals, anti-extrusion measures should be prepared and stored in a dry and ventilated place, avoid damp Quartz Crystal.

• When the solder, solder temperature is not too high, the role of the solder time not too long, so as not to produce an unstable change occurs within the Quartz Crystal.

• Ensure two-pin solder points are not connected, or will lead to Oscillator is stopped.

• The shear pin, should pay attention to the effects of mechanical stress.

• Solder, it should be cleaned to prevent the insulation resistance don’t meet the requirements.

Quartz Crystal Advantages:
1, Good stability, small changes;
2, Good accuracy, high precision;
3, Low power consumption, small excitation power;
4, Fixed (non-adjustable).

Quartz Crystal Structure:

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.

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.
