Working Principle of HC-49/U-S25175000ABJB

A quartz crystal works by stimulating an electrical current that oscillates or vibrates at a precise frequency, depending on its size, shape, and composition. This vibration produces a series of electrical pulses, which is then converted into sound or a radio frequency and used to control or modify a circuit or system.Due to the quartz crystals’ high stability, the oscillation and frequency of the crystals remain the same regardless of the temperature or pressure changes in the environment. They also have an extremely low ageing rate of less than 1 Hz per year. This property makes them ideal for use in clocks, timers, and frequency synthesizers, where accurate timing is essential.Also, due to the quartz crystal’s wide frequency range, they can be tuned to a variety of frequencies, allowing them to be used in multiple applications. Moreover, due to their small size, they are widely used in portable electronic equipment, where space is at a premium.
