Crystals - 495-25-141JB4I8 Application Field and Working Principle
Crystals are physical structures that contain a regular arrangement of atoms, ions or molecules which form a crystal lattice having a periodic arrangement of constituents in three dimensions. 495-25-141JB4I8 is a type of crystal used in various electrical and electronic devices, including oscillators, telecommunication transceivers, and transducers.
These crystals have several unique properties that make them well-suited for different applications. Some of these properties include excellent frequency stability, wide temperature range operating capability, low insertion losses, low aging rate, and low electrical noise. Due to these advantages, 495-25-141JB4I8 crystals have become a popular choice for many applications, such as oscillators, transceivers and transducers.
495-25-141JB4I8 crystals are very versatile in their application field and commonly used in various types of oscillators, such as voltage controlled oscillators (VCOs), chamber-controlled oscillators (CCOs) and crystal oscillators (XOs). These oscillators are used in various communication systems to maintain the frequency of an incoming signal and provide oscillating signals for the purpose of modulating data, transmitting data, or other communication activities.
Working Principle of 495-25-141JB4I8 Crystals
The most common oscillator design based on 495-25-141JB4I8 crystal contains an active inductor, circuit elements and a crystal that is connected between an implicit power supply. The crystal consists of two electrodes placed on the opposite faces of a piece of quartz crystal. The quartz material serves as a piezoelectric material, meaning that it exhibits ‘piezoelectric effect’ and produces a potential difference across its plates when voltage is applied to it or when subjected to mechanical force. When a voltage is applied to the crystal, it exhibits a change in its physical shape and size while releasing an electrical signal. This signal can then be used to control a signal.
In the oscillator circuit, the signal generated by the 495-25-141JB4I8 crystal is looped through an amplifier and active inductor for boosting the signal. This signal is then transferred between the two electrodes of the crystal at high frequency. At each cycle, the current amplified by the loop is tapped, whereby a voltage signal is developed across the crystal.
The signal is then transferred to the feedback capacitor and then again to the oscillator, enabling the circuit to maintain its oscillation. So, the 495-25-141JB4I8 crystal is basically used as a reliable and accurate frequency reference. It is also used in the creation of a built-in frequency standard, thus providing better accuracy and stability.
Conclusion
495-25-141JB4I8 crystals are extremely versatile and have numerous advantages when it comes to oscillator frequency stabilization and other electrical or electronic applications. This is due to their excellent frequency stability, wide temperature range operating capability, low insertion losses and other unique properties. The 495-25-141JB4I8 crystals are used in several electronic and electrical applications, most prominently in oscillators and also in transceivers and transducers. As part of these systems, the crystals are used to transfer, modulate, and receive data and information. The crystal is operated based on the piezoelectric effect, where an oscillating signal is generated when a voltage is applied to the crystal. The signal is then looped through an amplifier and active inductor, providing a constant frequency of oscillation.
