The two days before public opening, we installed the Eiosis booth, prepared the demo sessions and fixed a few last-minute bugs on AirEQ, our lead product, to make it behave correctly, as it will be tortured by visitors coming to try it live on the two iMacs we have on the booth.
I spotted some cool spots, but since everyone (including us) is getting their booth ready, it’s more like piles of junk everywhere, but I can’t wait to see it all prep’d up
Some NPO (Non-POlarized) capacitors may have a stripe on their package. Since this can’t be a polarization indication, you might wonder what it means.
A capacitor is made of two conductive elements separated by a non conductive element. In cylindric capacitors (both radial and axial), there is a central core for one conductive element, and an outer shell that makes the second, with some non-conductive substrate in the middle.
The mark on an NPO point to the outer shell. This can be interesting if you need an end of your cap to be grounded. Grounding the outer shell provides isolation from EMI and prevents noise getting in the capacitor.
