Crystals

A crystal is a beautifully ordered arrangement of atoms that repeat in a regular basis. Crystals can form from heavy metals such as gold and silver, as well as from minerals and organic compounds such as quartz and sugar. When the crystal structure is exposed to a certain frequency of external energy, a specific vibration is produced, which can be measured and interpreted.

The 402F400XXCDT crystal is a quartz crystal. It is an ultra-compact ceramic hermetically sealed high frequency component. It has a wide range of applications as its reliable timing accuracy, high frequency stability, high temperature stability and low cost. The frequency range of the 402F400XXCDT crystal is 32 kHz to 32.75 MHz, providing reliable stability in impedance matching with appropriate load capacitors.

The working principle of the 402F400XXCDT crystal is based on piezoelectric effect. Piezoelectric effect is the property of a material to generate an electric charge when it is mechanically stressed. Quartz is a piezoelectric material, and when an AC voltage is applied to its surface, it is distorted by a certain frequency proportional to the AC voltage. As the voltage is removed, the quartz crystal resumes its unstressed form, producing a vibration that is directly proportional to the applied voltage and frequency. This vibration is detected, amplified and rectified to produce a DC voltage, which is used to control the oscillation frequency of quartz crystal.

The 402F400XXCDT crystal is used in a range of applications such as low voltage power supplies, audio systems, and timing devices. It is often used as a master clock in numerous digital systems, such as microprocessors and counters, to control the timing of operations. It is also used to create a synthetic signal generator to produce an RF signal with a precise frequency, which allows precise transmission of sound, images and data.

In conclusion, the 402F400XXCDT crystal is a quartz crystal that is capable of producing a stable and reliable signal. Its wide range of applications demonstrate its versatility and ability to provide reliable frequency stability and timing accuracy in a multitude of applications.
