11. Agreement on this Specification
Should any part of the content of this specification become questionable, it shall be settled by
mutual deliberations.
12. Remarks on Usage
12-1.In case that such stronger shock and vibration, higher temperature that shall be specified
were to be applied to the resonator, it would occasionally become out of order. So please pay
plenty of attention to its usage.
12-2.This part is available for reflow soldering only. The ceramic resonator may be damaged in
case of reflow soldering at temperatures higher than 260 oC.
12-3.Ensure that your circuit design is fully characterized for your IC. For recommendations of
component values, please contact IC manufacturer or our local sales office before mass
production. Please note there may be some oscillation problems in case of not suitable
circuit design.
12-4.Storage condition
Please use the ceramic resonator within one year from the shipping date under room
storage condition less than 30 oC and 60%RH with the shipped package.
12-5.Fail-safe
Be sure to provide an appropriate fail-safe function on your system or subsystem to prevent
a second damage that may be caused by an abnormality or failure related to our product.
