Crystals have been widely used for decades in all kinds of electronics and applications. FA-128 25.0000MD30Z-AJ is one kind of crystal that has been widely used. This article will briefly discuss the application field and working principle of this crystal.ApplicationFA-128 25.0000MD30Z-AJ is a popular choice of crystal for a variety of electronic circuits and applications. It is often used as an oscillator in radio frequency applications, providing a highly accurate stable reference frequency. It is also widely used as an accurate timekeeping element in clock oscillators and watches. Its small size and low power consumption also make it well suited for low power applications such as mobile phones and wireless modems.Working PrincipleFA-128 25.0000MD30Z-AJ works by using the piezoelectric effect. A piezo crystal consists of a quartz crystal that has two metal electrodes attached to it, usually arranged in a cross pattern. When a voltage is applied to the electrodes, the crystal vibrates and resonates at a particular frequency determined by its geometry and the impedance of the attached electrodes. The frequency of oscillation is extremely stable and can be accurately controlled by adjusting the voltage applied.The crystal is able to maintain its resonance frequency over a wide range of temperatures, making it highly suitable for precision clock oscillators and other temperature sensitive applications. It is also highly resistant to noise and has excellent long-term stability.ConclusionFA-128 25.0000MD30Z-AJ is a widely used piezoelectric crystal with a range of practical applications. It is used as an oscillator in radio frequency applications and as a highly accurate, stable and long-term stable timekeeping element in clock oscillators and watches. It is small, low power and highly temperature insensitive, making it ideal for a wide range of modern electronics applications.
