Precision crystals are often used in oscillators and filters that serve as higher-end stable frequency references for personal communications systems, telecom switching systems, medical equipment, cellular phones, WAN/LAN equipment, test instrumentation, and satellite communications.

QCM crystals are used as sensors to determine mass changes as a result of frequency changes. In research environments, the most common QCM crystal applications include metal deposition monitors, chemical reaction monitors, biomedical sensors, and environmental monitoring applications, etc. Other applications include detection of mass, density, viscosity, adsorption, desorption, and corrosion.

TCXOs are used in telecom timing modules, wireless systems reference oscillators (microwave, etc.), precision instruments, and other frequency sensitive applications.

VCTCXOs are often used for frequency control in tactical radios, telecom timing modules, wireless systems, phase lock loop applications, and reference oscillators.
