Crystals are essential components for circuitry operations in a host of electrical fields. They are used for frequency control and for circuit tuning, aiding the construction of timing and precision circuitry. The 8Y-27.120MAHQ-T crystal is a type of crystal unit that provides a stable frequency for precision applications.

Application Field

The 8Y-27.120MAHQ-T crystal is find in many places, from the aerospace industry to automotive production and medical research. It is a popular choice for many applications as it is suitable for operating temperature range of -20°C to +70°C, while also being less susceptible to temperature shock compared to other crystals. The crystal is also ideal for battery-powered applications, such as portable radio and television, due to its low current consumption of 5 to 9mA.

The most common use of 8Y-27.120MAHQ-T crystal is in telecommunications equipment. It is ideal for use in high-speed circuits such as modems and digital switches, as it provides excellent accuracy over a wide temperature range and offers superior performance in terms of stability and reliability.

Working Principle

As a quartz crystal, the 8Y-27.120MAHQ-T crystal works when an alternating current runs through it, which causes it to oscillate between two positions or resonant frequencies. The crystal will maintain the same frequency regardless of the temperature which makes it an ideal component for precision components. This is in contrast to an ordinary quartz crystal, which loses stability when exposed to temperature changes.

The 8Y-27.120MAHQ-T crystal produces a frequency of 27.120MHz and a resonant load capacitance of 10pF. This means that it can produce a frequency of up to 120MHz with external loaded capacitance of 20pF. The crystal also uses a frequency overtone of 27.120MAHQ instead of 27.120MHz, which allows it to consume very low current.

The crystal requires an external circuit to provide the necessary bias and feedback to the crystal to ensure that it produces a steady output. The oscillator circuit is important because it sets the stage for the crystal to oscillate and the bias and feedback helps in stabilizing the frequency produced by the crystal. The crystal also needs to be mounted properly to ensure a good electrical connection between the pins. This will also ensure that there is minimum noise or distortion when the crystal is producing output.

Conclusion

The 8Y-27.120MAHQ-T crystal is a reliable crystal unit with a wide range of applications. It has a range of features that make it suitable for many precision applications, including low current consumption, excellent frequency accuracy, and resilience to temperature changes. The crystal also requires an external oscillator circuit to ensure that it produces a steady output and that it is connected correctly. With its numerous advantages, the 8Y-27.120MAHQ-T crystal is sure to be a popular choice for various projects.
