Is 100F ambient temperature (long-term) harmful to electronics if not powered on?

Are high ambient temperatures (say, up to 100 F in a non-air-conditioned house) harmful to electronics if the device isn't turned on, but simply being stored there?

(Thinking about consumer electronics, like a digital piano, or a PC, but not including electronics in cars which I understand are designed to withstand higher temperatures.)

Thanks.

Generally no. Operating temps are generally above 100F. But if you have things you are specifically concerned about, check a manufacturer spec sheet. It may list allowable storage temps.

Thank you!

Also, be cognizant of the humidity.
That may be more harmful than 100F.

Thanks. Do you know if there's an upper limit for it? (I could imagine RH soaring in the non-air-conditioned house. I know >50% is bad for books.)

Consider a vacation home in Florida.
Not used all the time, high temp and humidity.

Stuff rarely dies.

Thanks. That's a good point. I'll try to be careful of it, but hopefully there's some wiggle room.

Actually, it is probably not that high unless you have a leak. 80% is a typical storage upper limit.

Thanks. Yes, we actually get maybe as high as 80% RH in the basement, but the basement may have been constructed without dampproof membrane, or those kinds of things. In the bedroom where I'm storing these things, hopefully it won't get as high. I'll keep an eye on it, using the numbers you guys gave as guidelines. Thanks.
