EURO QUARTZ CX2HSM CRYSTAL Miniature SMD Crystal for Series Oscillators 16kHz to 600kHz FEATURES Frequency Range 16kHz to 600kHz High shock resistance Low ageing Designed for low power applications Full MIL testing available OUTLINE & DIMENSIONS Typ. Dim. A B C D E F G H I DESCRIPTION CX2HSM crystals consist of a high quality tuning fork resonator in a rugged, hermetically sealed ceramic package. CX2HSM crystals are intended for use in Series (two cascaded inverters) oscillator circuits. SPECIFICATION Specifications stated are typical at 25°C unless otherwise indicated. Specifications may change without notice. Frequency Range: 16.0kHz to 600.0kHz Standard Calibration Tolerance*: see table Motional Resistance (R1): Figure 1 Max = 16~169.9kHz, 2x typical 170~600kHz, 2.5x typical Motional Capacitance (C1): Figure 2 Quality Factor (Q): Figure 3 Min. is 0.25x typical Shunt Capacitance (C0): 2.0pF max.
