The most common application field of the 402F25022IJT crystal is in oscillators. It is an ideal frequency generator for various communication systems, for instance, as a time base of a spread spectrum communication system. The crystal is also used in micro-controllers, where an accurate timing source is required, or it can be used to drive data transfer. Other applications of the 402F25022IJT crystal include switching power supplies, programmable logic controllers, frequency dividers, memory controllers, digital-analog converters, telecom systems, automotive electronics, and IoT applications.

How does a 402F25022IJT crystal work? The crystal is made up of two main parts: the electromagnetic device and the vibrating quartz plate. The plate is cut and polished in such a way that when an electric current is applied, it develops a resonance circuit that oscillates at a set frequency. The resonance frequency of a crystal is determined by its size, shape, and the electric characteristics of the material from which it is made. The crystal is an excellent source of stable electrical signals of accurate frequency and can also be used for very precise frequency measurements.

The electric current passing through the 402F25022IJT crystal is used to induce a mechanical force to the quartz plate. The plate is made of quartz, which has very low piezoelectricity coefficients. This ensures low power consumption and a more stable oscillation in the resonance circuit. The electric current is used to excite the vibration in the quartz plate and convert it into an electrical signal at the required frequency. The frequency of the electrical signal is determined by the shape, size and design of the crystal.

The 402F25022IJT crystal is used in a wide range of applications, due to its simple and compact design, low power consumption, accurate frequency control, and superior performance. Its most common application field is in oscillators, micro-controllers, frequency dividers, switching power supplies, and telecom systems. By understanding the application field and working principles of the crystal, one can effectively use the 402F25022IJT crystal in their circuit design to solve various problems and tasks.
