Crystals

Crystals are the powerhouses of miniature electronic circuits, and the FA-20H 16.0000MF10Z-AJ5 crystal is no different. Composed of a quartz piece and two metal electrodes, these small, electronic components emit electrical signals at very precise intervals. Their application field and working principle is of critical importance in many electronic systems.

Application Field

The primary purpose of the FA-20H 16.0000MF10Z-AJ5 crystal is to send out regular electrical pulses. This concept applies to all crystals, and the application field is wide and varied. Manufactures typically use crystals on both consumer and industry-grade products, such as radio receivers, digital clocks and other consumer electronics. They can also be found in medical equipment, laboratory instruments and military systems. Crystals sources are also integral to many communications systems, such as computers, remote-control units, two-way radios and even television receivers.

Working Principle

Crystals generally consist of an enclosed quartz die, accompanied by two metal electrodes. In a standard household appliance, the circuit contains an oscillator, which eventually produces an alternating current whose properties depend on the crystal used. In the case of an FA-20H 16.0000MF10Z-AJ5 crystal, this alternating current occurs at a set frequency of 16.0000MHz, the speed at which electrical pulses are exchanged.

The crystal oscillator works on the principle of piezoelectricity, a phenomenon discovered in 1880 by Pierre Curie and Jacques-Yves LeCoultre. This phenomenon involves the compression of a quartz crystal, resulting in polarization in the form of stress and strain. At rest, the force experienced by the crystal is almost nil. However, when the voltage is applied to the crystal electrodes and the quartz is distorted by the electric field, it accumulates a charge. The charge is then stored, resulting in an oscillating electric field within the crystal. When the voltage is cut off, the electric field vanishes and the charge dissipates, restarting the cycle and sending out regular electric pulses.

Conclusion

The FA-20H 16.0000MF10Z-AJ5 crystal is an incredibly important electronic device, with a wide range of applications in almost all electronic systems. Its working principle is based on the natural phenomenon of piezoelectricity, which allows the crystal to vibrate at set frequencies and send out electrical pulses.
