Crystals are among the most versatile and widely used components. They are used in many consumer and industrial electronics applications, from powering computers to running radios and televisions. The HC-49/U-S19660800ABJB is a general-use crystal in consumer electronics and other applications. Its compact size and low cost makes it an attractive choice for many projects.

The HC-49/U-S19660800ABJB crystal is an AT-cut, full-size 20-MHz crystal. It has a frequency tolerance of ±5ppm and an operating temperature range of −20 to 85 °C. It is designed for use in oscillators, motor controls and other systems requiring precision timing. The crystal is housed in a 12.5 x 11.5 x 4.4 mm package, making it suitable for use in a variety of design environments.

The primary application field of the HC-49/U-S19660800ABJB crystal is in consumer electronics, where its low cost and small size make it ideally suited. It is also used in other industrial and scientific applications, where its tight tolerance and excellent temperature characteristics are useful. The crystal can be used for frequency stabilization in timing and control circuits, such as those used in motor control systems, as well as in its most common application, operating oscillators.

The primary working principle of the HC-49/U-S19660800ABJB crystal is based on the piezoelectric effect. When a voltage is applied to the crystal it contracts or expands along its Z axis. This movement creates a mechanical stress that excites the crystal and causes it to produce a mechanical vibration at a specific frequency. This vibration is then converted into an electrical signal, making it easy to use in electronic circuits.

The mechanical vibration can be tuned by altering the voltage applied to the crystal and the frequency of the electrical signal can be accurately measured. This allows the HC-49/U-S19660800ABJB crystal to be used to produce and control precise timing signals for a variety of applications. The crystal can be used to generate accurate clock signals for synchronizing digital devices, as well as for generating pulse width modulation signals for motor control applications.

In conclusion, the HC-49/U-S19660800ABJB crystal is an ideal choice for many projects, especially those where a low-cost, compact crystal is needed. Its low price, tight tolerance and wide operating temperature range make it a reliable choice for any application that requires precise timing signals. Its primary application is in consumer and industrial electronics, but it is also commonly used in scientific, industrial and research applications, including motor control systems, oscillators and frequency stabilization.
