Will a 0402 0.01 µF ceramic capacitor next to a 0402 0.1 µF ceramic capacitor have any power decoupling benefits?
I always understood that the point of using smaller capacitors in parallel was to provide low impedance at higher frequencies than the bigger capacitors, because the higher capacitance capacitors '...

Ceramic capacitors: how to read 3-digit plus 1-letter markings?
It seems that reading a ceramic capacitor value out of its written values is harder than decoding an Enigma machine.
I wonder if experienced users here does have a trick to quickly figure out these ...

How to derate a ceramic capacitor for DC bias
I understand that the capacitance of a ceramic cap is very dependent on the DC bias applied to the terminals. At rated voltage, I've measured a decrease of up to 70%, and I've heard it can go higher. ...

Capacitance vs. Frequency Graph of ceramic capacitors
I'm looking at ceramic capacitors on TDK and I see this graph
Does this mean above several hundred kiloHertz - or wherever the graph stops - that the capacitor no longer functions probably ?
