Crystals

Crystals are components made from either a single continuous piece of material called a monolithic crystal, or from multiple pieces of material called a composite crystal. While the different types of crystals have distinct uses and advantages, the most common type is the 445C33D30M00000 crystal.

445C33D30M00000 Application Field and Working Principle

Crystals of the 445C33D30M00000 type can be used for a wide variety of applications, ranging from telecommunications to automotive electronics. In particular, they are used to produce oscillations or frequency separators, as well as for generating precise and accurate timing signals.

The principal components of a 445C33D30M00000 crystal are an AT-cut plate, an internal electrode, an external electrode, and a resonator. The AT-cut plate is a quartz plate that is specifically cut as per a preferred angle, with two opposing plates separated by a thin quartz spacer, providing the required geometric configuration for the crystal. The cutting angle determines the overall tuning capability of the crystal, which is a primary factor influencing its precise frequency.

The internal electrode is then placed on the surface of the AT-cut plate, with the external electrodes arranged appropriately. Both these electrodes serve to transfer the electrical signals generated by the oscillator, and provide a potential difference that can be used to generate the required tuning.

The resonator is the most important part of the entire crystal, and is responsible for producing a precise and stable frequency. This is achieved by using a combination of resonator materials and plates, including ultra-thin piezoelectric plates, encased in a protective layer. The resonator creates a continuous oscillation at a stable frequency, forming the basis of the crystal oscillations.

The 445C33D30M00000 crystal is ideal for applications where stability and accuracy are of key importance, such as those requiring the production of precise timing signals. It provides greater stability and accuracy than alternate frequency sources, and is able to maintain its frequency even in the presence of a wide range of environmental conditions. This makes it valuable for use in telecommunications and automotive electronics, which rely heavily on precise and accurate timing signals for their operation.
