Crystals are crystalline materials used for various purposes including atomic energy, electronics, and measurement. A crystal is composed of atoms, molecules, and ions arranged in a regular, three-dimensional structure, with a definite orientation in space that gives it its characteristic shape. The atoms, molecules, and ions that make up a crystal are usually held together by electrostatic forces between particles, and their arrangement and orientation determine the crystal’s optoelectronic and mechanical properties.

Within the application of electronics, the most common type of crystal used is the 402F48012IJR. This crystal functions as a quartz oscillator. It is used in many digital applications such as watches, processors, and amplifiers. As a quartz crystal, the 402F48012IJR is made of a piezoelectric material that changes shape when electric current is applied, creating a vibration that can be used to measure time.

The 402F48012IJR crystal produces a very steady and consistent oscillation at a frequency of 12.8MHz when an AC voltage is applied. This frequency determines the speed of operation of electronic circuits, as well as the accuracy of the time measurement. The crystal vibrates in a particular mode, and the frequency of this mode can be tuned to produce a particular desired frequency. The higher the fundamental frequency of the crystal, the more accurate and consistent the timekeeping will be.

The 402F48012IJR crystal is ideally suited for oscillator applications in digital circuitry. These crystals are highly accurate and stable, particularly with regard to temperature. They are importantly also very cost-effective, making them ideal for use in various consumer electronics. These crystals also require low power and have a small footprint.

In addition to its use for timekeeping, the 402F48012IJR crystal can also be used for frequency modulation purposes. By applying a voltage to the crystal, it can be made to oscillate at frequencies higher or lower than its fundamental frequency. This can be used to encode or decode digital data, and is a commonly used technique for secure communications.

Finally, the 402F48012IJR crystal can also be used as a filter in electronic circuits. When a signal is applied to the crystal, it will resonate at its fundamental frequency and block signals at other frequencies. This technique can be used to reduce noise and ensure that only the signals of interest are passed through the filter.
