SMT Crystals Have Wide Frequency Range

In addition to a wide frequency range of 3.2 to 70 MHz, HC49SD surface-mount, low-profile crystals also have frequency tolerance of ±30 ppm at 25° C, frequency stability of ±50 ppm, and operating temperature range of 0°C to 70°C. Shunt capacitance is 7 pF, and the standard load capacitance for parallel standard crystals is 20 pF. Drive level is 0.5 mW.
