It's a widely known problem with roots in urban legend: Devices with motherboards failing in the early 2000s with a sudden ...

Take film capacitors — we all know they aren’t ... Thus if that side isn’t connected to the lower impedance side of whichever circuitry it resides in, it can pick up noise, while the inside ...

Effectively, the decoupling capacitor provides a low-impedance path at high frequencies and a high-impedance path at low frequencies. Ideally, a larger value capacitor would be better, but since ...
