The UM-1 and UM-5 crystal units from Nanjing Hualianxing Electronics Co. Ltd have an insulation resistance of at least 500 megohms and exhibit an aging rate of <5ppm per year. Both devices also have a drive level <100?W and a shunt capacitance <7pF. Operating temperature range is from -10C to 60C or -40C to 85C.

The UM-1 type measures 7.8-by-7.8-by-3mm and operates at a frequency range of 10MHz to 50MHz at fundamental mode or 24MHz to 100MHz at third overtone mode. The UM-5 measures 7.8-by-5.5-by-3mm and operates over 10MHz to 24MHz at fundamental mode or 24MHz to 100MHz at third overtone mode. Frequency tolerance is 10ppm to 50ppm.
