The above specifications are standard for this NDK product.
Custom-made specifications such as load capacitance and temperature characteristics are also available. Please contact NDK sales with your enquiries.
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
characteristics, heat and heat-cycle resistance and vibration resistance.
A surface-mount crystal unit that due to the resin seating attached to the AT-51 type
crystal unit maintains high-level electrical characteristics and reliability.
AT-51AD, AT-51CD and AT-51CD2 meet the requirements for re-flow profiling using
lead-free solder.
AT-51CD2 meets the requirements for re-flow profiling using lead-free solder.
