EURO QUARTZ CX16 TELEMETARY CRYSTAL Ultra-Miniature SMD Crystal 24MHz to 50MHz FEATURES Ultra-miniature SMD design, 2.0 x 1.2 x 0.4mm Frequency Range 24MHz ~ 50MHz High shock and vibration resistance Hermetically sealed Ceramic lid Excellent ageing characteristics Full military testing available OUTLINE & DIMENSIONS DESCRIPTION CX16 crystals are manufactured with an unique pholithographic and chemical milling process and are then sealed within a ceramic package for high stability and low ageing. The parts are available with tight calibration tolerances and high stability over temperature. With a fast start-up time the crystal is ideally suited to applications with space constraint and require components with low profiles. SPECIFICATION Specifications stated are typical at 25°C unless otherwise indicated. Specifications may change without notice.
