Introduction to Crystals and the 402F271XXCDT Application Field and Working Principle

Crystals are one of the most widely used components in electronics and are essential building blocks in a variety of applications. They are used in everything from watches to radio systems and can be found in a large range of different products. This article will discuss the application field and working principle of the 402F271XXCDT crystal, a popular quartz product used in many electronic products today.

What is a Crystal?

A crystal is a solid material with an ordered arrangement of atoms that forms a repeating three-dimensional pattern. Crystals come in a variety of shapes, sizes and materials, and each type of crystal has unique properties. The most common type of crystal used in electronics is quartz, a mineral composed of silicon dioxide (SiO2). Quartz is often chosen as the resonator material of choice in electronic circuits due to its excellent electrical and mechanical properties, such as high stability and reliability, low power consumption, and low insensitivity to shock and vibration.

The 402F271XXCDT Crystal

The 402F271XXCDT crystal is a quartz product manufactured by Fox Electronics. This crystal has a frequency range of 1.6 MHz to 158 MHz, and a maximum frequency tolerance of +/- 10 to 25 ppm, depending on the frequency. It has an operating temperature range of -20c to +70c, a storage temperature range of -40c to +90c, and a maximum load capacitance of 12 – 18pF. The 402F271XXCDT comes in a variety of package types, including leaded, surface mount, and commercial SMT packages.

The Application Field and Working Principle of the 402F271XXCDT

The 402F271XXCDT crystal is commonly used as a clock or frequency source in portable electronic products and also as a temperature compensated crystal oscillator (TCXO). It is also used in GPS systems and communication devices, as well as automobile electronics, industrial automation systems and consumer electronics. When a voltage is applied across the crystal, an oscillating electric field is created which causes the crystal to vibrate at a specific frequency. This frequency is determined by the crystal’s physical characteristics (e.g. size, shape and material composition). The oscillations are then used to control the system’s timing, create a stable signal for communication and synchronize electronic systems.

Conclusion

The 402F271XXCDT crystal is a high performance quartz product which is used in a variety of application fields, from consumer electronics to automotive, industrial and communication products. Its broad frequency range and excellent electrical and mechanical properties make it a popular choice for many applications. In addition, its relatively low cost and ease of use make it a popular choice for those looking for a reliable and simple solution.
