Crystals are materials with a regular arrangement of atoms and molecules that give rise to a regular repeating pattern in three dimensions. They come in a wide variety of shapes and sizes, from infinite macroscopic crystals to microscopic crystals which can only be seen through a microscope. One type of crystal, the 445W35B27M00000, is used extensively in electronic and communication industries as a Frequency Control Device (FCD). This article will discuss the application field and working principle of 445W35B27M00000.

Application Field

The 445W35B27M00000 crystal is a quartz crystal commonly used as an electronic component in electronic devices. It is used to generate precise and stable frequencies for analog or digital circuits. It is used as a source of oscillation and as a frequency control elements in radio, television, computer, microwave, cellular, and other high-frequency circuits. It can also be used in a variety of transducer applications such as thermistors, thermocouples, pressure transducers and chemical sensors.

The feature of the 445W35B27M00000 that makes it an attractive choice in these applications is its superior frequency stability, better than 0.5 parts-per-million (PPM) over a 100°C range. This is due to the fact that quartz is a very stable material and its natural frequency is consistent over temperature and time.

Working Principle

The 445W35B27M00000 crystal is made up of a block of quartz with two electrodes (metals) on the top and bottom surfaces. The crystal oscillator works on the principle of the piezoelectric effect. Piezoelectricity is a property of certain materials, including quartz, to produce a small electric charge when mechanically stressed. When an alternating voltage is applied across the electrodes, the quartz crystal variations in the electric field cause the crystal to expand and contract. This results in the generation of a precise frequency, corresponding to the mechanical stress applied to the quartz.

The frequency of the 445W35B27M00000 is determined by the size and shape of the crystal and is proportional to the applied voltage. The frequency can also be affected by the temperature, which is why the 445W35B27M00000 is designed to be highly temperature-compensated for precise and stable frequency output.

Conclusion

The 445W35B27M00000 crystal is a highly stable, temperature-compensated frequency control device that is used in a variety of electronic and communication applications. It works on the principle of the piezoelectric effect, which is the property of certain materials to produce a small electric charge when stimulated by mechanical stress. The frequency of the 445W35B27M00000 is determined by the size and shape of the crystal and is proportional to the applied voltage.
