Crystals are widely used in electronic equipment; 402F38433CDT is one of them.

Application Field

402F38433CDT has a series of resonant frequencies that make it applicable in various electronics, such as data communications, mobile and other telecommunications applications, industrial products such as energy meters, motor controllers, or applications running in the lower power range, like remote control or alarm systems.

Besides, 402F38433CDT is suitable for PC/104 Specifications, which covers a range of industrial grade PC sub-systems including IO boards, motherboards and complete computer systems.

Working Principle

the working principle of 402F38433CDT is based on its negative resistance. A microresistor is essentially a quartz crystal with electrodes attached to it. When the crystal receives an input voltage, internally generated stress causes microresistance to automatically track a negative resistance characteristic.

This negative resistance characteristic of the crystal is achieved due to the piezoelectric effect. When an external voltage is applied to the crystal, stress is induced inside the crystal, which alters the electrical current and resistance of the crystal, creating a negative resistance.

By taking advantage of this effect, the 402F38433CDT crystal can be utilized as an oscillator, generating accurately tuned signals with precise frequency jitter and low phase noise. The crystal’s frequency is determined by its mechanical dimensions, and it can be tuned slightly by application of an external voltage, which changes the amount of stress induced in the crystal.

402F38433CDT crystal is particularly suitable for precision timing, communication systems, clock sources, and other timing/crystal oscillator applications.

Conclusion

Overall, the 402F38433CDT crystal combines the qualities of an accurate crystal, low power consumption, and a small package size, making it an ideal solution for modern electronic applications.
