Midgrade? Might be an argument for low peripheral.

I'm guessing F1 and the 3A(mp?) means it's a fuse but not sure

My grades are my own opinion and not an official grade from Boardsort

F1 is a fuse. 100% sure. It's just a quality surface mount fuse. Yes. Those are gold plated end caps on the fuse. And yes. It is 3 amp rating.
I don't see me grading the board.

Nano fuses! Those gold caps are highly gold plated or silver bearing. This is one item I actually collect and refine myself.

If you can gather enough in quantity, BS will buy these at a specific rating. You can also find a jeweler.

These fuses and gold capped in-line resistors, have these style of caps on them. You have to remove the resistors cover/plastic/epoxy or enamel/paint to see the gold caps. (rare though) Mostly on the carbon composition types(fixed resistors).

Low Per as is, remove the ferrite CU winding, High Per

Always check ceramic boxed or ceramic wire wound resistors too. They do sometimes have heavy gold pins or the actual contact point itself; that's suppose to break connection on overload, is highly gold plated.

Spence1015. What are your comments on these two components? I am showing the original condition. And then when I cut them open. Those are ceramic hybrids. I value your opinion.

Sorry for the late reply Cat.

Those are neat. They're considered ICs, dual in-lines actually. I pull similar objects from audio equipment and old visual stuff.

From some kind of sound/audio equipment? or a general DC convertor for something?
If you look very close, you can see the gold tethers to the ceramic dies.

In most Hybrid ceramic units or microelectronic PCBS, they contain hazardous materials inside the substrate; don't break them.

They also usually are packed with goodies like so. Old power supplies contain ceramic hybrids too, I pull em' to put into High Per or Low tel.

The image above is very similar. Has the same contents inside; also considered an IC

Another really cool unit that boasts yummy, are the CCDs, CCFLs, and the light bars from computer scanners/faxers multifunction units; CSIs ( Scintillator ) Someone just posted a CCD in the , "What is it". I believe these can go into the new Gold legged, no gold capped ceramic IC, if ceramic; newer are plastic. Half of them don't have a gold inlay or legs, but still can go into a CPU category or IC.

They all break down very easy or desoldering IC. Only be weary of the tiny tube lights inside of them. They break easy like spaghetti noodles and are SHARP!

Examples of so;
