Here you can buy quartz oscillator, quartz crystal, SMD quartz, x-quartz. We have SMD quartz electronic parts and through hole electronic quartz components.

SMD = Surface Mounted Devices. A method for constructing electronic circuits in which the components are mounted directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD).

Through hole = construction method of fitting components with wire leads into holes in the circuit board. Both technologies (SMD and  through hole) can be used on the same board for components not suited to surface mounting such as transformers and heat-sinked power semiconductors.
