CX14SM AT CRYSTAL  
Ultra-Miniature SMD Crystal  
20MHz to 50MHz  
FEATURES  
Designed for infrared, vapour phase or epoxy mounting  
Low profile, (<0.59mm) hermetically sealed ceramic  
package  
OUTLINE & DIMENSIONS  
Excellent ageing characteristics  
High shock and vibration resistance  
Full military testing available  
Available with glass or ceramic lid  
DESCRIPTION  
CX14SM crystals are designed for applications requiring very small  
footprint and low profile (<0.59mm). Using micro-machining  
processes this hermetically-sealed crystal ensures high stability and  
low ageing.
