Crystals

Crystals are solid substances composed of atoms or molecules arranged in a three-dimensional repetitive pattern. In the context of electronic components, they are commonly used as frequency control elements in oscillators, filters and radio communication circuits. One such type of crystal is the 402F27022IJr, which is designed for use in frequency-controlled applications. This article will discuss the applications and working principles of the 402F27022IJr.

Applications of the 402F27022IJr

The 402F27022IJr is a frequency-controlled crystal oscillator, often used in mobile communications systems and power supplies. The 402F27022IJr is designed to be used in oscillator circuits to provide a stable and predetermined frequency. Additionally, the crystal oscillator can be used in the resonant circuit of diplexers, filters and other frequency-controlled circuitry. It can also be used for frequency synthesizers on radios, televisions and other electronic equipment. The 402F27022IJr has been designed to cover the frequency range of 400 to 500 MHz, making it ideal for use in mobile communication and power supply systems.

Working Principle of the 402F27022IJr

The 402F27022IJr is an oscillator crystal resonator that works on the principle of the piezoelectric effect. This effect occurs when an electric field is applied to a crystal, which causes the crystal to vibrate at a certain frequency. This frequency is determined by the type of crystal and its dimensions. The 402F27022IJr is made from a quartz crystal, which is cut and shaped to vibrate at a predetermined frequency when voltage is applied to it. This frequency can be adjusted by applying a variable voltage to the crystal, thus allowing precise frequency control for the crystal oscillator.

Conclusion

The 402F27022IJr is a frequency-controlled crystal oscillator that is widely used in mobile communication and power supply systems. It is designed to provide a stable and predetermined frequency range from 400 – 500 MHz. The 402F27022IJr works on the principle of the piezoelectric effect, in which voltage applied to the quartz crystal causes it to vibrate at a predetermined frequency. The frequency can be adjusted by varying the voltage, thus allowing precise frequency control for the crystal oscillator.
