THROUGH-HOLE CRYSTALS  
HC35 CRYSTALS (TO5)  
OUTLINES AND DIMENSIONS  
DESCRIPTION  
HC35 crystals are used in communications, aerospace and defence  
applications The crystal blank used in HC35 packages is capable of being  
manufactured to close tolerances and is readily produced with custom  
frequencies and specifications.
