Crystal 16.000MHz 49S 20PPM 20pF 40Ω
The Crystal 16.000MHz 49S 20PPM 20pF 40Ω is a passive electronic component that acts as a precision frequency determinant. The core of the device is a piece of quartz material that operates on the principle of the inverse piezoelectric effect . When an alternating current is applied across the crystal, it vibrates at its natural, characteristic resonant frequency, which, in this case, is precisely 16.000 MHz. This mechanical vibration is then converted back into a stable electrical oscillation, providing the essential, rock-solid clock signal required for modern digital systems.
