Do electronic components have an expiration date?
How long does it take to components to go bad if we store them at room (normal) temperature and humidity?
What components go bad sooner? (resistor, capacitor, transistor, …)
What are the best conditions for components storage?
Conditions of maintenance maybe are written in the datasheet, but is expiration date coming from the datasheet too?

Semiconductor parts I buy from Future sometimes come in hermetically-sealed antistatic bags, with silica gel inside.
Each come with a warning about humidity. (I will try to find one.) I believe the warning is parts should be used within six months once the package is opened.
I believe the issue is not about the silicon deteriorating. It is about moisture being absorbed by the package which may cause failure during the surface mount soldering process.
I have no reason to believe it is unique to the parts I buy from Future, and may apply to other parts with similar package properties.
