Crystal Units  
For Car Electronics  
AT-51 / AT-51AD / AT-51CD / AT-51CD2  
Features  
n
A crystal unit, ideally suited for the clock signal generating source of the  
CPUs for power trains and safety control devices, requiring extremity high  
reliability as part of an automobile’ s electronics system.  
Highly reliable under severe environmental conditions in terms of stable start-up  
l
characteristics, heat and heat-cycle resistance and vibration resistance.  
AT-51  
AT-51AD  
A surface-mount crystal unit that due to the resin seating attached to the AT-51 type  
l
l
crystal unit maintains high-level electrical characteristics and reliability.  
AT-51AD, AT-51CD and AT-51CD2 meet the requirements for re-flow profiling using  
l
lead-free solder.  
AT-51CD2 meets the requirements for re-flow profiling using lead-free solder.
