402F19233CLR Crystals

Application Field

The 402F19233CLR crystals are widely used in applications such as consumer and household electronics, automotive, industrial and military displays and monitors, calculators, cash registers, gaming systems, keyboards, printers, radio transmitters and receivers, telephones, watches and various consumer products. As the frequency range of Frequency Products is in the hundreds of megahertz, they are ideal for use in demanding applications where long life and high reliability is necessary.

Working Principle

Crystals are based on the piezoelectric effect of certain crystals such as quartz, sapphire, and tourmaline. The principle is that when an electrical voltage is applied to a quartz or other piezoelectric crystal, the crystal mechanically vibrates with a very specific and consistent frequency, which can be used as a frequency reference for electronic circuits.When the voltage is removed from the crystal, the mechanical resonance of the crystal continues, slowly decaying to the ambient temperature of the environment. This is the defining trait of a piezoelectric device, in that it will continue to oscillate with an unchanged frequency for long periods of time, up to around 30 years in some cases.At the center of a typical Frequency Products 402F19233CLR crystal is a quartz crystal that is shaped in an octagon. The crystal is mounted in a package that is hermetically sealed with a ceramic plate. The plate consists of electrodes, which serve as the input and output terminals to the crystal. To optimize the oscillation characteristic of the crystal, the electrodes are specially designed to match the crystal\'s mechanical parameters.In order to maximize the operating efficiency of the crystal, a full temperature range is programmed into the crystal during manufacture. The customizable temperature range is then adjusted to provide optimal performance at the various environments of operation.

Conclusion

The 402F19233CLR Crystals are used in a variety of applications requiring precision frequency control. The piezoelectric effect of the quartz crystal used in the frequency products guarantees performance that lasts up to 30 years, making it an ideal choice for a wide range of applications.
