The crystals are low profile with a very small land area.       Designed for surface-mount applications using infrared, vapour phase, wave solder or epoxy mount techniques Ideal for use with microprocessors Designed for low power applications Compatible with hybrid or PCB mounting Low ageing Full military environmental testing available Custom designs available Specification D (TO P) A D D B C E Outline CX-3-SM Package Dimensions Dimension Typical (mm) Maximum (mm) A B C D E Dimension “C” 6.73 2.62 1.27 1.32 Glass Lid (mm max.) 7.11 2.90 see below 1.52 1.57 Ceramic Lid (mm max.) 9.6MHz to 160MHz A: ±0.01% (±100ppm) B: ±0.1% C: ±1.0% 20pF (unless other specified) Load Capacitance: see table below Motional Resistance (R): see table below Motional Capacitance (C): see table below Quality Factor (Q): see table below Shunt Capacitance (C): 500mW max.
