What are Crystals?

Crystals are objects made of interlocking molecules that are arranged in a predictable pattern. This pattern forms a three-dimensional shape, known as a lattice structure. The molecules in a crystal usually have similar molecular geometry, allowing them to fit perfectly together. Crystals can be found in almost all materials, from game pieces to jewelry to rocks and minerals.

7M20020001 Application Field and Working Principle

The 7M20020001 crystal is a type of quartz crystal used for digital-to-analog conversion applications. The crystal has a size of 7mm x 2mm x 0.1mm and is manufactured by Sanken Group. Its working principle is based on piezoelectricity, which is a phenomenon in which an electric potential is generated when certain materials are physically deformed or subjected to a mechanical pressure.

The 7M20020001 crystal is used for two main purposes. The first is for digital-to-analog conversion, in which digital data is converted into an analog format. The second application is for oscillation, in which the crystal is used to maintain a stable frequency.

The 7M20020001 crystal can also be used as a resonator in various electronic circuits. It consists of a quartz crystal and two metal electrodes. A voltage applied to the electrodes causes the crystal to vibrate, and the frequency of the vibration is determined by the specific frequency of the crystal. By using the oscillatory characteristics of the crystal, the frequency of the circuit can be precisely controlled.

In addition to its application as a resonator, the 7M20020001 crystal is commonly used in timekeeping devices such as watches due to its excellent frequency-stability characteristics. It is also used in radio communication devices and temperature measurement instruments.

Conclusion

The 7M20020001 crystal is one of the many quartz crystals used in various digital-to-analog conversion and frequency control applications. Its main applications include digital-to-analog conversion, oscillation, resonator, and timekeeping devices. Its excellent frequency-stability characteristics make it suitable for a wide range of applications.
