SMD Communication Crystals
-------
-------
Acceleration tolerant SMD AT-cut quartz crystal in ceramic package with 6.0 mm x 3.5
mm footprint
-------
Product description
-------
Very small SMD AT-cut quartz crystal specifically designed to operate in vibration prone
environments. Parts are able to survive acceleration 20,000G and higher with minimal
parameter change. Vibration G-sensitivity significantly reduced. True SMD style, ceramic
package with metal lid, seamed sealed. The product is supplied on tape and reel.

• Navigation
• Military
• Other
-------
Features
• G-sensitivity down to 0.2ppb/G
• Low aging
• Up to 50,000G acceleration event survival
• Very good short term stability
