DESCRIPTION:  
Lowest profile SMT ceramic pack.  
Ultra low profile: 0.38 mm height  
SMD-package in Tape and Reel  
Ind. and Ext. temperature ranges  
High stability  
ThisSMDceramicpackagehasbeenspeciallydesignedforultralowprole  
telecom and smart-card applications. A special crystal manufacturing  
process is used to achieve improved electrical characteristics and a  
miniaturized blank size.  
Low aging  
Low power consumption  
High shock and vibration resistance  
For pick-and-place equipment, the parts are available in 12 mm tape:  
7” (178 mm) reel with 3’000 crystals
