Raltron's RH100 series surface-mount microprocessor crystals are available in a 3.2mm x 2.5mm x 0.7mm miniature ceramic package. The RH100 series crystals have a frequency range of 8 MHz to 156.250 MHz and are a design choice to replace the less mature crystals of the HC49. The RH100 features a minimum package size for 8 MHz frequency applications. Available frequency tolerances at room temperature are ±10 ppm and ±50 ppm, and temperature stability ranges from ±10 ppm to ±50 ppm. These surface-mounted crystals operate in the standard temperature range from -20°C to +70°C, and are also available in the extended temperature range from -40°C to +85°C.

     Targeted applications for the RH100 series include embedded computing devices, cameras, wearables, storage, personal digital devices, wireless applications, microprocessor clocks, portable medical devices, alerts, utility metering, smart home and other high-density applications.
