Introduction

Crystals are solid substances that are made up of a regular arrangement of atoms, ions, or molecules, in which a three-dimensional pattern of the crystal structure is formed by repeating its basic unit. The electrical and optical properties of crystals can be used to transfer or receive energy in different physical forms, such as vibrations and electrical signals. 7M12000146 is an electronic component in the form of a crystal, made of two pieces of ceramic with a small crystal inserted between them. Its application field is wide and includes both digital and analog communications, as well as oscillators and resonators.

Application Field

7M12000146 can be used in digital and analog communications. In the case of digital communication, it is used as a frequency reference, enabling transmission of data between two or more devices. The crystal is also used in set-top boxes and microwave ovens with its frequency stability, being highly accurate and capable of operating in a wide-range of frequencies. As for analog communication, it is used in oscillators and resonators, providing transmission of or reception of analog signals in an analog TV system, or in an PLC network.

Working Principle

The 7M12000146 crystal consists of two pieces of ceramic with a tiny crystal insert between them. The work of this component is based on the piezo-electric effect, in which mechanical stress on the surface produces a small electric charge. This effect can be used in both directions, allowing energy to be either transferred from an electrical signal to a mechanical vibration, or vice-versa. The electrical field generated by the crystal helps generate and control the frequency of an oscillator circuit, enabling the sending and receiving of signals over a distributed network.

Conclusion

7M12000146 is an essential component in a wide range of both digital and analog communications. Its frequency stability, accuracy, and wide frequency range make it an ideal choice for a variety of applications. The piezo-electric effect makes it capable of generating and controlling the frequency of an oscillator circuit, which makes it especially useful in oscillators and resonators. The 7M12000146 crystal is thus a valuable component in the field ofcrystalline engineering.
