7V-27.000MAAB-T

Crystals contain an arrangement of atoms, ions or molecules in a regularly repeated pattern, and form the basis of many technologies. 7V-27.000MAAB-T is a crystal, which is often used in radio frequency (RF) and microwave circuits. This article will explain the application field and working principle of 7V-27.000MAAB-T crystal.

Application field of 7V-27.000MAAB-T

7V-27.000MAAB-T is a miniature SMD package containing a parallel resonant crystal, which is available in 8.0 x 3.0 x 1.5 mm package. It offers an excellent temperature stability with good frequency stability, and is widely used in applications such as wireless transceivers and microprocessors.This crystal is suitable for applications requiring an operating frequency between 26.8 to 27.2 MHz, with a frequency tolerance of ±50 ppm or better. 7V-27.000MAAB-T works well in a wide range of temperatures between -20°C and +70°C, and features a slightly higher load capacitance value than other packages.

Working principle of 7V-27.000MAAB-T

The 7V-27.000MAAB-T crystal consists of two quartz plates with electrodes. The plates are joined together and vibrate when a voltage is applied. This vibrations create an alternating electric field, which produces an oscillation at a specific frequency depending on the device’s mechanical dimensions. The frequency of oscillation is determined by the dimensions of the crystal, i.e. the frequency of vibration is dependent upon the mechanical size. This feature is used for creating a frequency near the center of the frequency range by adjusting the dimensions of the crystal plates. The plates also have piezoelectric properties, which means that when a voltage is applied to the crystal, it will cause a mechanical displacement. This displacement will have an effect on the resonance frequency, creating a temperature-dependent frequency variation. The temperature-dependent frequency variation can be compensated by selecting a load capacitance to increase the crystal frequency stability.
