Choosing a Decoupling Capacitor Size for Power Integrity
Decoupling is an important aspect of power integrity, and the typical method for providing stable power to digital ICs like FPGAs and MCUs is to use one or more decoupling capacitors. Using a decoupling capacitor in isolation, i.e., without closely spaced power and ground layers, was fine in the past, particularly in systems with slower rise times and …

Capacitor, Inductor, LC, Pi Filter circuits for DC power supply
it has been decades since i did linear power supply design (and i wasn''t very good at it), and i don''t remember how to choose the inductor value. BTW, i always used to make C2 bigger than C1 in a pi filter, so as to …
PCB Capacitors: Why Is It Important and How to Choose?
While polarized capacitors have higher capacitance values and are often used in power supplies, they also have a higher leakage current and can act as short circuits when used incorrectly. Non-polarized capacitors have lower capacitance values but are better suited for applications like AC coupling and bypassing.
