The HC49/US Crystal Oscillator is a passive quartz crystal resonator used to generate a stable and precise clock frequency for electronic circuits. It operates through the mechanical resonance of quartz material, providing accurate timing references for microcontrollers, microprocessors, communication systems, and oscillator circuits. Available in multiple selectable frequencies, it allows designers to match exact application requirements. The standard HC49/US through-hole package offers strong mechanical stability and easy integration into PCBs and breadboard-based projects.
