Crystals:

CM309E9830400BBKT is an important component used for frequency control. As a class of devices, crystals are capacitive nonlinear components that are used to generate and keep a steady frequency in oscillators. The CM309E9830400BBKT itself is a quartz crystal, which consists of the main component: a quartz crystal spindle, some additional parts such as case, lid, holder and lead frame, and a wide range of coatings and metalizations. The CM309E9830400BBKT is just one type of crystal, and many specific types of crystals are available with different parameters to satisfy different applications.

Applications of CM309E9830400BBKT

The CM309E9830400BBKT can be used mainly in oscillators and Radio Frequency (RF) applications. It is mainly used in the fields of TV, radio, computer and radio communication. This crystal can also be used in high-frequency electronic devices such as mobile phones and the Global Positioning System (GPS). In addition, it can provide the devices with a reliable, high-precision frequency control, and can easily satisfy customer’s demands. Furthermore, the CM309E9830400BBKT has a specially designed structure with various coatings, which can provide excellent stability in high temperature, humidity, or other difficult working environment.

Working Principle

The CM309E9830400BBKT works on the basis of the piezoelectric effect. Basically, this phenomenon is an electric charge caused by pressure which can generate a voltage across the material. The CM309E9830400BBKT consists of a quartz crystal spindle and additional parts such as case, cover, holder and lead frame. The quartz crystal spindle can generate electric charge when it vibrates, which produces an alternating current (ac). This alternating current will produce an oscillating voltage across the crystal, and that voltage is called the oscillation frequency. By adjusting the size of the quartz crystal spindle, engineers can control the frequency of the oscillator. The quartz crystal spindle can be cut at different angles for different frequency ranges. The output frequency is controlled by the quartz crystal.In addition, the CM309E9830400BBKT also works on the principle of resonance. In this principle, when the frequency of an applied voltage to the crystal is equal to the natural frequency of the crystal it will start to resonate and generate more energy. The frequency produced by the crystal is determined by the crystals’ size and shape.The CM309E9830400BBKT crystal can be used in both voltage-controlled oscillators (VCO) and pressure-controlled oscillators (PCO). In VCOs, the applied voltage is adjusted to change the frequency of the oscillator, while in PCOs, the applied pressure is adjusted to change the frequency of the oscillator.Conclusion

The CM309E9830400BBKT crystal is an important device which is used to generate and keep a steady frequency in oscillators, which can meet the requirements of various applications such as TV, radio, computer and radio communication. It works on the basis of the piezoelectric effect and resonance principle. For VCO, the applied voltage can be adjusted to change the frequency of the oscillator, while for PCO, the applied pressure can be adjusted to change the frequency of the oscillator. With its specially designed structure with various coatings, the CM309E9830400BBKT can provide excellent stability in high temperature, humidity, or other difficult working environments.
