Raltron Electronics Corp. has introduced two series of surface-mount tuning fork crystals that are suitable for accurate time of day and other read-out requirements found in state-of-the-art portable equipment such as blood glucose level meters, thermometers, and blood pressure readers. The RT3215 and RT4115 series also may be used in lab diagnosis units, industrial timers and other consumer applications that call for small, high-density assemblies.

Both series are offered at a frequency of 32.768kHz at a tolerance of ±20 ppm within a temperature operating range from -40° to +85°C. The RT3215 measures 3.2 x 1.5 mm, while the slightly larger RT4115 measures 4.1 x 1.5 mm. The devices are RoHS compliant.
