Crystals: AT-4.000MAHC-T Application Field and Working Principle
Crystals are oscillatory components that help to determine the frequency of electronic circuits. AT-4.000MAHC-T crystal is used in various electronic products, such as radios, television sets, cameras, mobile phones and computers. This crystal has a frequency of 4.000 MHz (4 million hertz), and its operation is based on the effects of piezoelectricity and quartz.
Piezoelectric effect
The AT-4.000MAHC-T crystal utilizes the piezoelectric effect. In this phenomenon, which occurs when certain materials are exposed to mechanical stress, the molecules that make up the material are electrically polarized and become electrically charged. This phenomenon can be observed in several materials, such as quartz, tourmaline and ceramics. In the AT-4.000MAHC-T crystal, this effect is produced by the quartz material and produces electrical and mechanical vibrations.
Quartz oscillator
The AT-4.000MAHC-T crystal is made of highly pure quartz that is kept in an oven and subjected to a temperature of 150 degrees Celsius. This quartz is cut to specific dimensions, depending on the frequency of the crystal to be produced. The AT-4.000MAHC-T crystal is cut to a thickness of 4 mm, so that it generates a frequency of 4.000 MHz. The crystal is mounted in a metal holder, where two slender metal pads are in contact with the quartz. When an electrical oscillation is applied to the crystal, the quartz deforms, expanding and contracting, thus generating electrical and mechanical vibrations. This oscillator is responsible for producing the frequency stability required for radio and television reception, among other applications.
Application fields
The AT-4.000MAHC-T crystal can be used in various electronic products. Its use allows a device or appliance to operate at a specific frequency (4.000 MHz), consistent and stable. Thanks to this crystal, things like radios, televisions and mobile phones can receive signals successfully and without interference. This crystal can also be used in computers, allowing them to accomplish certain tasks, such as the calculation of decimals, in a certain period of time.
Conclusion
The AT-4.000MAHC-T crystal is a critical component designed to provide frequency stability in electronic circuits. This crystal oscillator is based on the principles of quartz and the piezoelectric effect and can be used in a variety of electronics products, such as radios, televisions, mobile phones and computers. AT-4.000MAHC-T is a crystal that can provide reliability and accuracy for users in the reception of signals.
