Crystals
Crystals are a class of materials with a regular, ordered arrangement of atoms or molecules, which are also referred to as unit cells. This arrangement creates a crystalline structure that is highly stable and can be replicated throughout a larger object. The most common types of crystals found naturally are salt crystals, such as halite and quartz, while artificial crystals are created using processes such as epitaxy, Czochralski Pulling, and hydrothermal methods. Crystals have a wide range of functional properties in applications such as optoelectronic, photonic, and piezoelectric materials.
495-2578125-2JB4I8 Application Field and Working Principle
The model number 495-2578125-2JB4I8 is a type of polycrystalline quartz crystal, which is used in communications and electronics to generate oscillations of specific frequencies over a wide range of temperature. Oscillators of this type consist of two electrodes that are attached to a quartz resonator of predetermined size, model and frequency. An oscillatory voltage is fed to the electrodes and a corresponding frequency is generated that is determined by the properties of the crystal.
The 495-2578125-2JB4I8 crystal is primarily used in telecommunications, broadcasting and military applications. It is also used in WiMax, M2M and IoT systems. The model is also useful in automotive and aerospace applications.
Some of the unique features of 495-2578125-2JB4I8 crystal are its tolerance to temperature and high accuracy. The crystal guarantees excellent temperature stability, which is important in applications that require high precision. It also offers a very low-noise level, which is particularly advantageous in applications such as radar systems that use low-noise amplifiers. This crystal also has a wide-temperature range and can operate at temperatures of up to 200 degrees Celsius.
The working principle of 495-2578125-2JB4I8 crystal is based on the principle of the piezoelectric effect. Piezoelectricity is the property of certain materials that undergoes a change in electric polarization when mechanical stress is applied. If an alternating voltage is applied to a piezoelectric material, it will start to vibrate and generate an oscillator frequency that is determined by the size, model and frequency of the crystal. This effect is used in 495-2578125-2JB4I8 crystal to create a stable, accurate oscillator frequency over a wide range of temperatures.
The 495-2578125-2JB4I8 crystal is a reliable and cost-effective solution for applications that require a high degree of accuracy and stability over a wide range of temperatures. The model is also highly reliable and offers excellent temperature tolerance and low-noise performance. It is a versatile crystal that can be used in a variety of applications, from telecommunications and broadcasting to the automotive and aerospace industries.
