Crystals

Crystals are a unique form of matter that form from a liquid or gas, and when created, a crystal lattice is formed, taking on a symmetrical three-dimensional shape. Many crystals are naturally-occurring and can be found in nature, but artificial crystals can be created through various means as well. Crystals have a variety of applications and usages, depending on their qualities and properties.

FH2400049 Application Field and Working Principle

The FH2400049 crystal unit is an electronic component used primarily in radios and communication devices. It consists of an oscillator and an amplifier, mounted on two stalks, and consists of a thin disc made of quartz which vibrates when an external voltage is applied. Its vibrational frequency is determined by the thickness of its quartz material and the size of the metal plates that make up the crystal. It has a very low temperature coefficient and can maintain a precise frequency under wide temperature variations.

When the FH2400049 crystal unit is required to oscillate, an alternating current (AC) signal is connected across the metal plates, causing the quartz to vibrate. The AC signal changes in intensity as the quartz vibrates, changing its frequency and thus generating an oscillating voltage. This voltage is then amplified within the crystal unit, producing an oscillating current of a desired frequency. This current can then be used to power the radio or communication device in which the FH2400049 unit is installed.

The FH2400049 crystal unit has many applications in radio systems and communication devices, ranging from the very simple to the most sophisticated. It is used in fixed frequency radio transmitters, receivers, and transceivers, as well as for tuning radios, television receivers, and a variety of other electronic devices. It is also used in digital circuitry for frequency division and as a timed oscillator for counters and timers.

The FH2400049 crystal unit easily lends itself to any low frequency or fixed frequency application requiring extremely tight and stable frequency control. Its tight frequency control and low temperature coefficient make it an ideal choice for highly accurate frequency-controlled applications.
