CTS Model 406 surface mount quartz crystals are engineered with a high Q quartz resonator, making them suitable for diverse commercial and industrial applications. These crystals offer a frequency range of 7.0 to 54MHz, a standard frequency tolerance of ±30ppm, and a frequency stability of ±50ppm. They are packaged in a hermetic ceramic surface mount format and are ideal for IoT devices, wireless communication systems, FPGA/microcontroller applications, and more. The crystal's design ensures reliable performance across a wide range of operating conditions, including temperatures from -40°C to +85°C.
