AT-cut crystal

An AT-cut crystal is a specific type of quartz crystal commonly used in electronics for its precision in timekeeping. The "AT" refers to the angle at which the crystal is cut from the quartz material, optimizing its performance for stability and frequency consistency. AT-cut crystals are widely used in devices like watches, clocks, and communication equipment because they maintain a steady oscillation frequency when an electric current is applied. This reliable frequency helps keep time accurately, making these crystals essential components in many modern technologies.
