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
OUTLINE & DIMENSIONS
Ceramic lid
Excellent ageing characteristics
Full military testing available
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.
