QUARTZ CRYSTAL (often identified as Xtal, External Crystal Oscillator, because the crystal oscillator unit is often used as an external circuit) also known as quartz crystal resonator or crystal oscillator, is an electronic component that uses the piezoelectric effect of quartz crystal (also known as crystal) to generate high-precision oscillation frequency, and belongs to passive components. This component is mainly composed of quartz wafer, base, shell, silver glue, silver and other components. According to the lead condition, it can be divided into two types: DIP (with lead) and SMD (without lead). The current common main package models are

DIP: HC-49S/DIP, 2*6 DIP, 3*8 DIP;

SMD Seam: 1.2*1.0mm, 1.6*1.2mm, 2.0*1.6mm, 2.5*2.0mm, 3.2*2.5mm, 5.0*3.2mm, 7.0*5.0mm, HC-49SMD; 

SMD Glass: 5.0*3.2mm.


At present, although quartz crystal have tended to be miniaturized, such as the size of 2.5*2.0mm, 2.0*1.6mm, 1.6*1.2mm and 1.2*1.0mm, etc., the quartz crystal SMD3225 still occupies a large proportion, and its advantages are stability, good precision and high cost performance. Compared with 49S, SMD5032, etc., the passive quartz crystal SMD3225 can save a lot of space on the PCB board, in addition, in the welding method, it can reduce the increasing labor cost, and also it is the most important point that SMD quartz crystal can greatly reduce various hidden dangers of damage to crystal oscillators caused by hand soldering, such as the temperature and welding time control of the electric soldering iron, the treatment of solder residues, etc., improper handling of these human factors will greatly affect the normal operation of the crystal oscillator and cause poor power on the circuit board. Therefore, the quartz crystal SMD3225 is widely used in most consumer digital smart electronic products due to its package size and cost-effective advantages.
