General Description The ultra-miniature CX-4V-SM quartz crystals are hermetically sealed in a very small surface-mount package measuring 5.0mm x 1.83mm. The high quality tuning-fork resonator is intended for use in Pierce oscillators. (Single inverter.) Surface-mount - infrared, vapour phase, wave solder or epoxy mount techniques Low profile, hermetically sealed package Available with glass or ceramic lid High shock and vibration resistance Custom designs available Full military environmental testing available Specification D (TO P) Frequency Range: Calibration Tolerance: Motional Resistance (R1): Motional Capacitance (C1): Quality Factor (Q): Shunt Capacitance (C0): Load Capacitance*: Turning Point**: Calibration Tolerance***: Drive Level: Temperature Coefficient (k): Note: Frequency (f) deviation from temperature (t0) = A F D B C E Outline CX-4V-SM Package Dimensions Dimension Typical (mm) Maximum (mm) A 5.00 5.33 B 1.83 2.16 C - see below D 0.97 1.22 E 0.51 0.76 F 0.64 0.89 Dimension “C” Glass Lid (mm max.)
