402F20033CKT Crystals

Application Field and Working Principle

Crystals are an essential component in modern electronics, playing a key role in circuitry, and more specifically, oscillators. The 402F20033CKT crystal is one example of a crystal oscillator, which is specifically used in circuit applications. As its application is widespread, it is important to be aware of the device\'s construction, composition, and the specifics of its working principle.

Construction and Composition

The design of the 402F20033CKT crystal is extremely simple. It is composed of a specialized quartz crystal piece bound inside an aluminium can. It also features additional leads that are used to contact the crystal. All components come enclosed in an epoxy package very similar in size to that of an integrated circuit. The device is available with an hermetic sealed package.

The quartz crystal that is mounted inside the can features an exact cut that corresponds to one of the few desired resonant frequencies of an oscillator – which for the 402F20033CKT is 33.4kHz. Quartz crystals are also incredibly consistent, allowing for very precise functioning operation.

Working Principle

The 402F20033CKT crystal finds its application primarily in oscillator circuits, as mentioned above. It is important to understand what an oscillator is, in order to understand the working principle of a crystal. An oscillator is a device that produces an oscillatory signal (alternating current) of a certain frequency. This particular frequency is determined by the resonant frequency of the crystal inside the 402F20033CKT package.

Inside the oscillator, the quartz crystal works in two different ways, it can act as a generator or a resonator, depending on how it is wired up. The quartz crystal works, by vibrating at a constant frequency when a voltage is applied across its two leads, with amplitudes that are directly proportional to the frequency of the voltage, hence the crystal is called an "oscillator".

If the circuitry is designed properly, the has crystal the ability to vibrate continuously at the exact resonant frequency, which is why crystals feature in many different types of circuit applications, providing very accurate timing.

Conclusion

The 402F20033CKT Crystal is an incredibly small device, but an incredibly powerful tool in the right hands, offering a high-precision of frequency and a consistent and stable output that can be used in numerous applications. With its versatility, this crystal is one of the most featured in a variety of circuitry, and thus its importance should not be diminished.
