【Summary】 Quartz crystal is short for quartz crystal resonator. Silicon dioxide crystals are cut into very thin wafers in a certain direction, and then the two corresponding surfaces of the wafers are polished and coated with a silver layer, and the pins are drawn out as two poles to be encapsulated, which constitutes a quartz crystal resonator. It has a very stable intrinsic frequency.

It has a very stable intrinsic frequency.

Quartz crystal has a small size, good stability and other characteristics, has been widely used in military and civilian communications radio, microwave communications equipment, programmable telephone exchanges, radio synthesis testers, mobile phone transmitters, high-grade frequency counters, GPS, satellite communications, remote-controlled mobile equipment, etc., mainly used for single-chip clock circuit, has also been widely used in air conditioners, microcomputer chips in the clock circuit.
