EEVblog 1677 - An Interesting Effect with Fuses (EXPERIMENT)

[EEVblog]

An experiment to test an interesting effect with fuses.

Did you just put them into the Freezer at -17°C until they reached temperature or did you follow any specific thermal shock?

Btw. Here is the old video:

10 minutes. You got me for 10 minutes.

I got got. You were able to exploit my material weakness.

Time zones, mate.

Grok agrees:

OMG! Now I wonder the fuse shipments that go through freezing transport phases (unheated airplane cargos, polar regions of the world) how they do it.
There is a place for a certificate of non-refrigeration during transport and stocking

Time zones, mate.

Really? What are they?

Grok agrees:

Grok both an LLM and a Musk product, isn't it?

https://duckduckgo.com/?q=%22jones+effect%22+fuse shows many results, none related to EEVBlog. Why am I not surprised

After seeing this and realizing that no matter how you look at it everything is a fuse I tossed a 250 W SMPS into the freezer and set it to -20°C.

Deficiency before freezing: 8 %
Deficiency after freezing cycle: 6 %

More experiments will be required because the change in efficiency isn't in line with the resistance change measured on a simple fuse. The problem is that I'm not a metalurologist.

Now do the same with a SRF.

Efficiency before freezing: 8 %
Efficiency after freezing cycle: 6 %

Fixed spelling above.
The FET resistance should drop so that might be the main increase in efficiency.

Yeah, for that we need to turn to this Youtube channel called The chemical path, formerly known as the signal path.
