Crystals

Crystals are substances with orderly periodic arrangements of atoms, ions or molecules. Their external structure is usually of regular shape and it is also known as its crystalline form. Crystals can be found in many materials, ranging from simple components of electronic circuits to complex structures with highly ordered structures.The 402F20033CDR is one such crystal. It is a quartz crystal which is used in many applications involving oscillators and filters. In this article, we will look at the 402F20033CDR’s application field and working principle.The 402F20033CDR is a frequency-temperature compensated doubly-rotated quartz crystal. It is used in various electronic communication circuits due to its stability and resilience. Examples of applications for the 402F20033CDR are frequency synthesizers, computer clocks, radio transceivers, and WiFi systems.The functioning of the 402F20033CDR is based on its crystal structure. The crystal is made of quartz, which is piezoelectric. This means that when voltage is applied to it, the crystal vibrates at a specific frequency. The 402F20033CDR is cut and polished in a certain way to ensure a clear and consistent vibration.The way the 402F20033CDR works is quite simple. When voltage is applied to the crystal, electrical signals are generated which are proportional to the frequency of the crystal. These signals can then be used to adjust other circuits so as to maintain an oscillation of a desired frequency.For example, in a frequency synthesizer, the oscillator listens to the signals coming from the quartz crystal and adjusts its own output until it is at the specific frequency as set by the crystal. In this way, the frequency synthesizer can maintain a stable output frequency for a long period of time, even when the temperature changes.The 402F20033CDR is an excellent choice for any application which requires a crystal oscillator. Its frequency-temperature compensation ensures that the oscillator maintains a stable frequency, even over a wide range of temperatures. Its reliability and durability makes it a great choice for any application which needs accurate and consistent frequency regulation.
