🐭 MOUSE RECAP
Older mice like mine don't have electrolytic capacitors and is why I didn't mention mice in my video, but "sfiera" at the 68kMLA kindly showed me there are indeed electrolytic caps in the newer Mac Plus edition mouse: bit.ly/2H8yNuL
Have a newer edition mouse? Just add 2pcs of this electrolytic cap to your Mouser Cart: bit.ly/38VdZT3
(Tantalum replacements never need to be replaced, but the TAP476M010SCS is over $5 each. Yowza!)
