Crystals have been used for many centuries as resources in signal processing, timekeeping, and frequency control. In modern technologies, crystals play increasingly important roles in a variety of fields such as telecommunications, aerospace, navigation, and even consumer electronics. Crystals are now essential parts of Quartz crystal resonators, Acoustic Wave Filters, Oscillators, and so on.

7A-14.31818MAHK-T is a type of crystal with a frequency of 14.31818MHz and a tolerance of ±7ppm, in which “7A” is the type, “14.31818” is the frequency and “MAHK-T” is the tolerance. The 7A-14.31818MAHK-T crystal finds numerous applications in consumer electronics and optical instruments such as Global Positioning System (GPS), digital camera, radio broadcast receivers, telecom systems, and so on.

The working principle of 7A-14.31818MAHK-T crystal is based on the piezoelectric effect. The piezoelectric effect is an intrinsic mechanical property of certain crystal materials, in which an applied mechanical force can generate an electric charge, and vice versa. 7A-14.31818MAHK-T has a cut-in thickness of 0.010” (or 0.25mm), and it is composed of a flat base plate, an outer electrode plate, a textured plate and a conductive coating. The crystal material is sandwiched between the plates, and the conductive coating is applied to the one or both surfaces of the textured plate. When an electrical signal is being applied to the crystal, it produces mechanical vibrations, and the crystal then oscillates at a fixed frequency with a very high initial stability, making it suitable for low frequency signal oscillation.

In summary, 7A-14.31818MAHK-T is a crystal with frequency of 14.31818MHz and a tolerance of ±7ppm, and its applications range from consumer electronics, GPS and optical instruments. It works based on the piezoelectric effect, in which an applied electrical signal produces mechanical vibrations.
