The impedance of a capacitor is not just 1 over omega C once ESR, ESL, DC bias, and PCB mounting are involved. This guide explains how real capacitors behave across frequency and why the lowest-value part is not always the best bypass choice.

PCB silkscreen is not cosmetic when reference designators, polarity, test points, and connector labels have to stay readable after assembly. This guide shows what to print, what to leave out, and where silkscreen mistakes create real manufacturing trouble.
