Crystals – 445W33S12M00000 Application Field and Working Principle

Crystals are types of elements, which contain atoms or molecules that have a purposefully arranged, periodic and repeated pattern of physical properties. These properties can be electrical, acoustic, optical, magneto-optic, thermal, and/or chemical. Crystals are used for multiple applications and can be found in electrical and optical components, especially those used for communication, thermoelectric components, energy storage and generation, opto-electronic components, and optically active materials. The 445W33S12M00000 is a type of quartz crystal that features a ceramic-over-metal (CoM) SMT package. This hybrid package combines the performance characteristics of a quartz crystal with the robustness and durability of an SMT package design. It is engineered for communication, radio frequency and microwave applications, such as navigation systems, WiFi, Bluetooth and other communication-based applications. The 445W33S12M00000 demonstrates excellent electrical and mechanical performance and is able to offer a combination of frequency stability, tuning sensitivity, mechanical shock, and thermal stability. Its highly robust design makes it adaptable to various temperatures, shock, and vibration. Working Principle It is well-known that a quartz crystal works by dilating and contracting with an applied electric field. The frequency of the oscillations created by this oscillation-contraction-oscillation cycle depends on the size of the quartz crystal.At a certain frequency, the oscillations created by the quartz crystal will create a standing wave or oscillation that will cause the crystal itself to oscillate or vibrate. This vibration creates a specific frequency which can be used to either measure the time or transmit and receive communication signals. In the case of the 445W33S12M00000, it is used for digital communication applications.The piezoelectric effect is what makes quartz crystals so special and efficient. Essentially, a quartz crystal will produce a voltage when an external force or stress is placed upon it. This is because quartz is a brilliant piezoelectric material and can produce electrical energy when it is subjected to pressure, and the level of energy produced depends on the frequency of the crystal. Once a quartz crystal has vibrations at a particular frequency, a sine wave can be produced by the crystal itself. As the pressure is increased, a higher frequency is produced. This frequency is then sent to the amplifier, where it is amplified and sent to the modulator. Here, it is modulated to create a communications signal.Conclusion The 445W33S12M00000 quartz crystal is a highly efficient, robust, and energy-efficient crystal that can be used for digital communication. Its small package size and piezoelectric effect make it ideal for applications that require precise frequencies, such as navigation, WiFi, Bluetooth, and other communication-based applications. Its piezoelectric effect creates a supersonic frequency that is amplified and modulated to create a communications signal. The 445W33S12M00000 offers excellent electrical and mechanical performance and is able to offer a combination of frequency stability, tuning sensitivity, mechanical shock, and thermal stability.
