Crystals are small items used to create torsional oscillator circuits, and the ST2012SB32768Z0HPWB4 crystal is one of them. In this article, we will talk about its application field and working principle.

Application Field

ST2012SB32768Z0HPWB4 crystal is suitable for controlling the main clock of PDA (personal digital assistant) as well as other kind of consumer products. With it, consumer products can achieve excellent performance in functions such as audio and video output. Besides these consumer products, it is also applicable in the field of medical equipment, such as cardiac monitors, ultrasound imagers, endoscopes and some other medical testing devices. To sum up, its application field covers almost all areas in consumer products and medical fields.

Working Principle

This crystal is based on the torsional oscillator circuit. Typical oscillator circuits work by charging and discharging a capacitor, but this oscillator works by vibrating a tiny quartz crystal. The quartz crystal contains crystallographic planes in its plane of symmetry, and these planes can be cut at its ends. When an alternating current runs through such a quartz crystal, its ends vibrates at the frequency of the alternating current. This frequency is determined by the thickness of the quartz crystal, which is the frequency of the crystal.

ST2012SB32768Z0HPWB4 crystal uses quartz as the basic material with a frequency range of 32.768 KHz. It is usually made with ceramic casing, with electrode on both end of the quartz. By of alternating or direct current through the electrode, the quartz will generate a high precision wave frequency that is not only stable, but also indicates a certain waveform. Such waveform can be used to control and stabilize voltage, or used to measure or control other parameters in circuits.

Conclusion

In conclusion, ST2012SB32768Z0HPWB4 crystal is a 32.768 KHz quartz crystal, which is suitable for controlling the main clock of PDA and other consumer products, as well as medical equipment such as cardiac monitors. Its working principle is based on the torsional oscillator circuit, where the crystal vibrates and generates a specific waveform frequency to be used to control and stabilize voltage, or other parameters in circuits.
