#257: Power Supply Decoupling & Filtering: why we use multiple caps in different locations

w2aew

Why people recommend it

A w2aew demonstration of why boards use several decoupling capacitors of different values in different places, and what that does to the supply rails.

Watch for: Pair with a datasheet for specific values

In their words

Video showing the effect of decoupling on the power rails:

Use case B [video] As for the capacitor voltage ratings it always should be larger than your maximum supply voltage.
