402F20022ILT Application Field and Working Principle

402F20022ILT crystals are commonly used in radio communications, consumer electronics and automotive applications. They are also used in controlling frequencies in power supply circuits, medical equipment, military and aerospace applications.

402F20022ILT crystals are miniature quartz plates, which are constructed with an interdigitated capacitor arrangement to maintain the resonant frequency of the oscillator circuit. The active elements in the structure are the electrodes, which are typically formed on a quartz substrate and overlaid with Gold or other conductive materials on both sides.

These miniature quartz plates are designed so that the electrical signal generated by the oscillator is fed back to the quartz crystal, which then amplifies the signal, resulting in an output oscillation frequency that is very precise. The active components of a 402F20022ILT crystal are known as the electrodes or resonators, which are composed of a conductive material and are typically either Gold or Platinum.

The application field of 402F20022ILT crystals includes radio communications, consumer electronics and automotive applications, control of frequencies in power supply circuits, medical equipment and military/aero applications. These crystals are also used in many types of frequency control such as clock oscillators, phase locked loops (PLLs), crystal oscillators, saw resonators and temperature compensated crystal oscillators (TCXOs).

When it comes to working principle, the 402F20022ILT crystal works on the principle of Piezoelectricity. It vibrates at a specific frequency depending on its design and the materials used in its construction. The resonance frequency of the 402F20022ILT crystal can be adjusted by changing the distance between the two electrodes. The operating frequency of the crystal is determined by an electrical network formed by the electrodes, the capacitors, and the feedback networks.

The frequency of the crystal can be tuned by varying either the capacitance or the inductance of the electrical network. The frequency can also be varied by changing the materials of the electrodes, the distance between them, or the shape of the crystal. Additionally, the frequency of the crystal can be adjusted by varying the temperature of the environment, or by the external loading of the crystal.

The 402F20022ILT crystal has a very precise frequency stability and low power consumption. It has a wide frequency range from 1 MHz to 500 MHz and a frequency tolerance of +/-20ppm.

Overall, the 402F20022ILT crystal is one of the most commonly used crystals in applications ranging from radio communications, consumer electronics and automotive tasks to medical and military/aero applications. It is a miniature quartz plate designed with an interdigitated capacitor arrangement to maintain a high precision output oscillation frequency. It functions on the principle of Piezoelectricity and is capable of a wide frequency range and a frequency tolerance of +/-20ppm.
