Crystals: 402F160XXCDT Application Field and Working Principle

Crystals are an essential component in a range of circuit applications and have multiple uses. 402F160XXCDT crystals are among the most commonly used crystals in electronic circuit boards and their application fields. In this article, we will be looking into the application fields and working principle of 402F160XXCDT crystals.Firstly, looking into its application field, the 402F160XXCDT crystals are primarily used as frequency control devices. It can be used in many areas where frequency control is of chief importance such as: frequency dialers, digital clocks, telephone circuits, television sets, and in high frequency applications. It is also commonly used in oscillator circuits, to generate an exact and continuous output frequency.As for its working principle, the 402F160XXCDT crystal has a simple and straightforward design. It consists of two quartz plates with an electrode attached in-between. An electrical charge is put on the quartz plates, and the pressure between them gets split into two vibrations. One vibration is known as the fundamental mode, and it is usually the desired output frequency. When the quartz crystal is therefore electrically and mechanically excited, it creates a mechanical resonance frequency. This frequency is then amplified, and the amplified signal is used in a given circuit.Moreover, because of its high frequency, the 402F160XXCDT crystal can also be used in very high frequency (VHF) applications. This is because of its high frequency stability, due to its exceptional temperature stability and low series resistance. Also, since the 402F160XXCDT has a frequency range from 10kHz to 250MHz, it has the ability to operate over very wide frequency ranges.It also has a condition of high overtone series behavior. This means that when it is excited with an overtone, it behaves like its fundamental mode of vibration, i.e., it will have the same frequency as the fundamental mode of the crystal. For example, when the overtone is excited at a higher frequency than the desired frequency of the crystal, its frequency will increase, and when it is excited with a lower frequency, its frequency will decrease. This makes the 402F160XXCDT crystal ideal for use in an oscillator circuit, as it can easily be adjusted to a desired frequency.In addition, the 402F160XXCDT crystal is also preferred over many other crystals, due to its exceptional shock resistance, which ensures the crystal vibrates for a longer period of time, even when subjected to mechanical shocks. Its high frequency stability also ensures proper circuitry operation in adverse conditions, such as in strong magnetic fields.The 402F160XXCDT crystals are thus an important component in many applications, due to their desirable characteristics. Their use in frequency control devices, VHF applications, and oscillators, is testament to the wide range of uses they have in electrical circuit design. As such, they are an essential component used in many electronic circuits.
