This is where an rh and temperature monitoring system of the storage environment is critical to prove conformance to j std 033.
Electronic component storage temperature.
Conventional electronic components are designed to operate over a specified temperature range with upper limits generally set at 70 c for commercial applications 85 c for industrial applications and 125 c for military applications.
In 1993 in the frame of columbus project we got an esa contract to assess the long term storage for high reliability components.
Without data to show conformance to the required rh levels in your storage system you are forced to bake the parts before use which can add to corrosion and possible component damage.
Can be accepted if less than 2 two years old ii.
Many components have a storage temperature range of 40c some are 65c to between 100c to 160c.
Just like with any electronic component increased temperatures accelerate the aging process.
Component shelf life storage condition requirements for electronic suppliers uncontrolled when printed ge proprietary or page 5 of 9 transmitted electronically ga src 0003 rev.

In other words it is expected to have a shorter mean time to failure at high temperatures than at say for instance ambient temperature.
We have extensive experience in eee parts engineering procurement and storage.
Electrical components for use at a later date.
The device will operate effectively within a specified temperature range which varies based on the device function and application context and ranges from the minimum operating temperature to the maximum operating temperature or peak operating temperature.
Long term storage eee components.
These operating temperature ratings generally satisfy the demands of the dominant.
An operating temperature is the temperature at which an electrical or mechanical device operates.
Storage grounds should be free of litter debris and sheltered from possible adverse weather conditions.
There are also many types and sizes of storage facilities but all must provide the same environment for the proper storage of electronic components.
Long term storage was one of our early studies.
Introduction semiconductor parts are most often specified for use in the commercial 0 to 70 c and to a lesser extent in the industrial 40 to 85 c operating temperature range.
The specifics of your components would need to be checked.
0 3 2 active components including semiconductors oscillators and diodes etc.
The answer to your storage temperature question is related to the lifetime of the device.
More to the point is humidity as the moisture sensitivity level determines how long the device may be exposed to particular humidity levels without damage at reflow.
