Precautions for the use of passive smd quartz crystal:
 The design of SMT surface mount crystal resonators is compatible with most automatic mounting processes, but some processes may produce excessive impact, which may damage the crystal inside this product. Therefore, please fully test the installation of this product before mass production.
 If the PCB may be warped, please ensure that the degree of warping does not negatively affect the working characteristics or welding conditions of this product.
 Avoid installation and processing by ultrasonic welding, as this method may propagate excessive vibration inside this product, which may become the cause of characteristic deterioration and non-oscillation.

The resonator (Xtal) is a package of a quartz crystal. This chip is cut from a quartz crystal in a certain way and has undergone a series of vacuum operations such as shaping, polishing, electrode plating, and adjustment. It can oscillate at a specified frequency with a very high Q value. Xtal is a passive component and does not contain an oscillating circuit, but is closely connected to the IC chip containing the driving circuit in terms of circuit distribution.
