402F54033CJR Application Field and Working Principle

Crystals are essential for well-designed electronic circuits. The 402F54033CJR crystal from NDK has the capabilities to produce high stability and accuracy for the most demanding applications. It comes with a small size, offering around 3.2 mm x 1.5mm, making this crystal ideal for space-constrained and high-reliability applications.

Its application area varies from GPS receivers, base stations, mobile phones, PCs, oscillators, robotics and instrumentation, to automotive and medical equipment. Depending on the type of crystal oscillator used, the applications vary. For the 402F54033CJR, it is specifically used for frequency references and control applications.

Working principle

A crystal generates a high-precision signal by vibrating when an electric field is applied to it. Even though the electric field will not cause a physical deformation of the crystal, it will cause the oscillations to grow, and the crystal will generate a signal with a frequency which is proportional to the applied electric field. The frequency is determined by the particular frequency of the reference crystal.

There are some factors that can influence the output quality and performance of the crystal such as temperature, mechanical stress, and quality of the oscillator circuit. The 402F54033CJR, however, offers superior performance due to its superior temperature characteristics, tiny dimensions, and lack of temperature drift.

Performance Characteristics

The 402F54033CJR has been designed with a number of performance characteristics including tolerance and stability, and temperature characteristics. The crystal is often referred to as having a \'tolerance\' or \'stability\' measurement.

Tolerance is a measure of the range of possible frequency values for the oscillator and is usually expressed in parts-per-million (PPM). The 402F54033CJR has a tolerance of 250 PPM. This means that the oscillator will usually fall within the 250 PPM range of the specified frequency, so this oscillator is suitable for relatively precise clocks and timekeeping applications.

The stability of the oscillator is also a factor that needs to be taken into account. The 402F54033CJR has a stability of ±25 PPM. This means that the frequency of the oscillator will not be affected by changes in temperature or other environmental factors. To ensure that the crystal operates correctly, it is important to install it in an appropriate environment and maintain it correctly.

Conclusion

The 402F54033CJR crystal from NDK solves many design problems due to its advanced performance capabilities. It enables the most demanding applications, such as those in the medical, automotive, instrumentation, and robotics fields to be more precise, efficient and cost-effective. Its small size also allows it to be used in applications that require limited space.
