Crystals: 402F260XXCJT Application Field and Working Principle

Crystals are essential components in our day-to-day lives. They are used in a variety of devices from communication systems and medical equipment to car safety systems. One of the modern crystals used for such purpose is the 402F260XXCJT model.The 402F260XXCJT is an ultra-stable crystal device specifically designed for enhanced performance in applications requiring wide bandwidth and reliability in a miniature surface-mount package. It provides excellent electrical performance with a large frequency range of 2.5 to 2.75 GHz and a frequency tolerance of +/- 10ppm across the temperature range of -40 to 85°C.In addition to its attractive frequency response, the 402F260XXCJT also offers an adjustable center frequency. This makes it very suitable in various applications, such as portable communication systems, including WLAN, Bluetooth, and 3G/4G, satellite communications, as well as military and medical applications.The 402F260XXCJT crystal also offers exceptionally low noise coupled with excellent phase noise performance. This low phase noise is essential for many modern data communication applications, such as timing synchronization and pulse arrival detection. The high-stability of the 402F260XXCJT provides significant savings in power requirements and improved reliability while allowing more simultaneous transmissions in dense and noisy environments.The 402F260XXCJT crystal has a wide variety of air-coupled, Convection Reflow, and Reflow soldered field applications. The crystal also has a modularity and design flexibility in choice of packaging and various placement variables. Furthermore, the crystal is RoHS compliant and comes with halogen-free finishing.The working principle of the 402F260XXCJT crystal is based on the piezoelectric effect, which occurs when electrical charges are generated in certain materials when mechanical stress is applied. This piezoelectric effect forms the basis of the crystal’s operation: when an alternating current is applied, the crystals vibrate at their resonant frequency. These vibrations are precisely timed and their frequency can be accurately regulated and maintained across the entire operating temperature range.The 402F260XXCJT’s ability to maintain a very precise frequency provides the high stability necessary for many advanced applications. This stability allows it to be used in mission-critical systems, as well as for precision time synchronization. The stability of the crystal also allows for improved system accuracy, reducing design times and enhancing performance by eliminating the need for extra external components.Overall, the 402F260XXCJT crystal provides the ideal foundation for precision timing and fast data communications, while offering excellent electrical performance, outstanding frequency stability, and superior phase noise performance in a compact form factor. Its wide range of applications, design flexibility, and high-performance characteristics make the 402F260XXCJT crystal an excellent choice for any application requiring a robust and reliable source of precise timing.
