Crystals have proven to be an essential component in the workings of electrical and electronic products. For instance, C-2 120.8475K-P is a compound crystal module with an operating frequency of 120.8MHz, comprising a crystal and load capacitors. These crystals are typically used in a wide array of industrial, medical and engineering fields. In this article, the working principle, application field and typical environment of C-2 120.8475K-P crystals will be discussed.

Working Principle

The C-2 120.8475K-P is composed of two primary components, a quartz crystal and load capacitors. The quartz crystal is fitted in the crystal module and, when energised by an oscillating signal of the right frequency, will generate its own oscillations. The signal generated will be in line with the frequency the crystal was originally ‘cut’ to - this is known as the resonance frequency. Load capacitors form part of the whole structure, connecting the crystal to the circuit it will be connected to. The load capacitors act to match the output impedance of the crystal to the input impedance of the circuit, allowing for optimal performance. Once in use, the crystal can function either in a series or parallel trapping arrangement, as determined by the application in question.

Application Field

The application field for the C-2 120.8475K-P is vast, mainly because of its relatively high frequency. Common places where this crystal would be used are radio and television receivers, as well as radio transceivers. Furthermore, these crystals can be used in missile guidance systems, GPS systems and ultrasound scanners. Lastly, as the technology involved with them is constantly advancing, these compounds can often be found in newer technology such as cellphones.

Typical Environment

The C-2 120.8475K-P crystals are best used in an environment with relatively low temperature and humidity. It has been determined that the optimal temperature range is between -40℃ and +85℃, with a permissible temperature range of -55℃ and +125℃. It should however be noted that at either extreme, the characteristics of the components may change slightly. Furthermore, the humidity should be kept to a maximum of 95%, as per the optimal operating environment.

In conclusion, the C-2 120.8475K-P crystal module is a versatile device with several usages, mainly in the electronic and communications fields. Its composition of a quartz crystal and load capacitors enable it to function as a tuning device, with optimal characteristics kept within a certain temperature range and humidity. As with any crystal, its characteristics can change due to different environmental effects, so care should be taken when operating them.
