Crystals: 7B-50.000MAAJ-T Application Field and Working Principle

Crystals, an important part of all electronic products, are widely used in oscillation and reception circuit. Among them, 7B-50.000MAAJ-T series is a kind of inverted mesa-shaped packaged crystal which is commonly used for field monitor and main monitor.This type of crystal has two electrode pins and utilizes the SMA female end. The case size is 6.05mm x 9.30mm, and the head is a flat copper surface with two gold-plated side contacts. Based on the different external conditions, some resources recommend that the solder heat on the chip should not exceed 260℃ for the protection of the crystal. As for its working principle, the 7B-50.000MAAJ-T crystal consists of three layers: the lower electrode, the piezoelectric substance and the upper electrode. The lower electrode is usually made of gold or silver alloy with a thickness of 200Å to 2500Å. The piezoelectric substance layer is made of quartz, lithium sulfate, or mercuric oxide piezoelectric material and has a thickness of 10μm to 50μm. The upper electrode is usually made of chrome, gold or silver alloy with a thickness of 150Å to 500Å.When a voltage is applied to the crystal, the crystal will produce a mechanical vibration. And when the mechanical vibration is stimulated by an external applied force, a voltage will be generated in the crystal. Through this principle, 7B-50.000MAAJ-T crystal is applicable in a variety of circuits for oscillation and reception.In terms of application fields, 7B-50.000MAAJ-T crystals are mostly used in field-controlled monitors for their small size and low power consumption.
