Quartz crystal oscillator is a quartz crystal resonator made of quartz material, commonly known as crystal oscillator. 
It plays the role of generating frequency, has stability and good anti-interference performance, and is widely used in various electronic products.

The structure of the quartz crystal oscillator (crystal oscillator for short) is a resonant device made of the piezoelectric effect of a quartz crystal (structured body of silicon dioxide). 
Its basic structure is roughly as follows: Cut a thin slice at a certain azimuth angle (referred to as a wafer, it can be square, rectangular, or circular, etc.), coat silver layers on its two corresponding surfaces as electrodes, and solder a lead wire on each on the pins, coupled with the package shell constitutes a quartz crystal resonator, referred to as quartz crystal or crystal, crystal oscillator. 
Its products are generally packaged in metal shells, but also in glass, ceramic or plastic packages.

Due to AKM fire in October, 2020, many suppliers are not accepting new order for Quartz crystal oscillator.
But Kingtronics team can help you, please feel free to share us your request.

Japan's Asahi Kasei (AKM) semiconductor factory broke out fire on 21st October and ceased production. 

The impact of the fire on the supply and performance is still unclear. Many customers are worried about the TCXO L/T and production status . 

Kingtronics can support you steady L/T around 3~5 weeks with RoHS certified.. welcome your inquiry!

Kt Kingtronics offers leaded quartz crystal HC49UHC49S and SMD quartz crystal HC49SMD. The quartz crystal market, in general, requires hands on customer service. Quartz crystals are manufactured for frequencies from a few tens of kilohertz to tens of megahertz. More than two billion (2×109) crystals are manufactured annually. We also stock crystals in most popular package styles, frequencies and specifications for quick delivery.

49USMD crystals are low profile surface mount crystals with the same footprint as standard HC49 and HC49-4H crystals. 49USMD crystals are ideal for use in low cost, mass-market applications but are also able to be produced to close tolerances when required. With a broad frequency range from 3.200MHz to 90.000 MHz, the HC49SMD can serve as a low cost solution in virtually any application or market. The HC49SD is available in surface mount (SMD) packaging only.

Quartz is used in the making of sandpaper, optics, glass, liquid filters, circuit boards, computer components, cement, mortar, and jewelry. Quartz crystals are also piezoelectric meaning when an electrical current passes through them they vibrate a small amount. Time can be measured from the vibrations of the quartz crystals so quartz crystals are often used in clocks.

Quartz crystals may either operate in a fundamental mode or in an overtone mode. Below frequencies of around 25 MHz crystals are normally designed to operate in their fundamental mode, whereas above this they will normally be designed for overtone operation, although with manufacturing techniques improving higher frequency crystals are becoming available. The mode is therefore an important element of the crystal specification.

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.
