The other parameters are guaranteed to be within specified characteristics by NDK design. Inspection data is not submitted for mass production lot. But only if requested, a copy of first lot production data will be submitted. 7. Precaution in the storage Please keep the oscillator in the ordinary temperature and humidity that are suggested as below table. Temperature Humidity Period Before taking out of dry bag +5 C to +45 C 10 % to 75 % RH 6 months After taking out of dry bag +30 C max. 70 % max. 168 hours * (table) *It is desirable for the oscillator to be used within 168 hours after taking out of dry bag. Please pack the oscillator into used dry bag with a desiccant and seal it up by heat sealer etc. In case the heat sealer is not available, sealing up with cellophane tape or a vinyl tape will do.
