Crystals: 402F27133CKT Application Field and Working Principle

Crystals, also known as quartz crystals, are a type of electronic component used for timing control and signal generation. Comparing to other traditional timing parts such as oscillators or clock generators, crystals are more accurate, thus well-suited for demanding applications. In this article, the application field and working principle of the 402F27133CKT will be explained to provide a better understanding of this specific model.

Application Field of 402F27133CKT

The 402F27133CKT specifically is a quartz crystal with frequency of 27.133 MHz. It is made of AT-cut quartz crystal and has inverse frequency-temperature characteristics. With a frequency stability of ±100ppm across its operating temperature range of -40°C to +85°C, it is ideal for a wide range of applications, including medical, automotive, GPS, military, and telecom. It is commonly used in signal generation and timing control, such as PLL, clocks, and frequency dividers.

Working Principle of 402F27133CKT

Quartz crystals generate oscillations when an electric current is running through them. The oscillations are determined by the geometry of the crystal itself, therefore the frequency of the oscillations can be reproduced very precisely. The 402F27133CKT utilizes an AT-cut quartz crystal, which because of its physical properties vibrates at a frequency of 27.133 MHz when current is applied. The frequency of the oscillations remains relatively stable over temperature change, thus providing high accuracy and precision even in extreme environments. The 402F27133CKT is designed to withstand typical temperature changes from -40°C to +85°C without significant frequency drift, ensuring good performance in any environment.

Conclusion

Crystals are a key component in many electronic circuits, and the 402F27133CKT is an example of a precision quartz crystal optimized for high accuracy and performance even in extreme temperature conditions. Developed to meet the exacting needs of medical, automotive, GPS, military and telecom applications, the 402F27133CKT quartz crystal provides excellent stability, accuracy, and reliability.
