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!

Murata posted news in the website that trimmer capacitors will be discontinued after 2021 March. As a competitor, we suppose that TZR1 Series (Ultra-small and thin with external dimensions of 1.5(W)x1.7(L)x0.85(H)mm) and TZW4 Series (Compact size: 4.2(W)x5.2(L)x2.6max.(H)mm) have no replacement product in the market for the same capacitance and size.

Could you please think about using Kingtornics ceramic trimmer capacitors KKT series small size with external dimension of 3.2(W) x 4.5(L) x 1.5(T) mm? Unique construction with no plastic material provides superior soldering heat resistance to maintain excellent characteristic performance after reflow soldering. It is suitable for high frequency circuit due to high self-resonant.
