3. CHARACTERISTICS
Units and values indicated with { } in this specification are the former units and the specified values.
Standard atmospheric conditions:
Unless otherwise specified, the standard range of atmospheric conditions for making
measurements and tests is as follows:
Ambient temperature: 15℃ to 35℃
Relative humidity : 25% to 85%
Air pressure : 86 to 106 kPa
If there is any doubt about the results, measurements shall be made within the following limits:
Ambient temperature : 25℃±1℃
Relative humidity : 63% to 67%
Air pressure : 86 to 106 kPa
Operating temperature range:
The operating temperature range is the range of ambient temperatures at which the quartz crystal
oscillator can be stored without damage. Conditions are as specified elsewhere on these
specifications.
Operating temperature range: -10℃ to +70℃
Storage temperature range:
The storage temperature range is the range of ambient temperatures at which the quartz crystal
oscillator can be stored without damage. Conditions are as specified elsewhere on these
specifications.
Storage temperature range: -40℃ to +85℃
