EURO QUARTZ
DESCRIPTION
CX9SM crystals are designed for applications requiring very small
footprint and low profile (<1.0mm). Using micro-machining processes
this hermitaclly-sealed crystalensures high stability and low ageing.
FEATURES
Designed for infrared, vapour phase or epoxy mounting
Low profile, (<1.0mm) hermetically sealed ceramic package
Excellent ageing characteristics
High shock and vibration resistance
Full military testing available
Available with glass or ceramic lid
Custom designs available
