Introduction

Crystals, a group of materials with highly organized atomic lattices, are used in a variety of professional fields, mostly in the ones related to electronics and telecommunications.Particularly, the 7V24000002 crystal is a ceramic, one of the most common models used by professionals due to its high frequency and stability.This article aims to explain both its application field and its working principle; the source of its advantages and the limitations associated with its use.

Application field

The 7V24000002 crystal is primarily used in the telecommunications field due to its stability and compatibility with multiple frequency ranges. It is also used in other related industries such as radio and satellite communication and in electronic circuits, where its presence can reduce noise and drifts in given conditions. In relation to the latter, the 7V24000002 crystal can be used in tuned circuits to optimize the working frequency, such as in the Radio Frequency Identification (RFID) technology.In addition to telecommunications, 7V24000002 crystals can also be used in the electronics industry for digital clock oscillator circuits. They can be used in the so-called quartz clocks, which are devices that need highly precise timing, such as in wristwatches, computers and navigational systems. Last but not least, the 7V24000002 crystal can also be employed in oceanographic depth finders and seismometers.

Working Principle

At a microscopic level, the 7V24000002 crystal is composed of a quartz crystal, two metal electrodes and two capacitors. The capacitors, when a voltage is applied, store charge on both the electrodes. The quartz crystal, on the other hand, is a mineral composed of silicon dioxide lattices arranged in a highly ordered fashion, responsible for the resonance process of the crystal.When an AC voltage is applied to the set of electrodes and capacitors, resonance occurs due to the formation of loops between the quartz, the capacitors and the electrodes. These loops act in succession, producing a linear alternating electric current capable of sustaining an external electric field.In consequence, if the frequency applied to the crystal is exactly the same as the one for which it is designed, it will become a resonator able to sustain the applied electric field field at a determined frequency and regardless of the external conditions. As a result, 7V24000002 crystals have high frequency and stability.

Advantages and Limitations

The main advantage of 7V24000002 crystals is their high frequency stability and low power consumption, capable of providing a precisely controlled frequency in a broad range of frequency bands. Other than that, they are non-volatile frequency sources meaning that they only need an application of voltage to work. Last but not least, they are relatively cheap in comparison to other frequency source methods, such as rubidium oscillators and atomic clocks.On the flip side, the main disadvantage of 7V24000002 crystals is its limited frequency accuracy, compared to other frequency sources. Furthermore, they are sensitive to humidity variations, to certain temperatures and to other environmental conditions, which can lead to their frequency drift if the temperature or humidity is not regulated.

Conclusion

7V24000002 crystals are one of the most commonly employed models in the telecommunications field due to its stability and compatibility with multiple frequency ranges. At a microscopic level, it is composed of a quartz crystal, two metal electrodes and two capacitors, which, when an AC voltage is applied, resonate due to the formation of loops between them, producing a linear alternating electric current.The main advantages of using 7V24000002 crystals are their high frequency stability and low power consumption, as well as their non-volatile nature and cost-effectiveness. On the contrary, its main disadvantage is its limited frequency accuracy compared to other frequency sources.
