Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the ...

As we have seen in part I and part II of this series [1], there are no inherent wear-out mechanisms in ceramic capacitors. And yes, as covered in part II, the high dielectric Class 2 capacitors (X7R) ...
Decoupling capacitors have long been an important aspect of maintaining a clean power source for integrated circuits, but with noise caused by rising clock frequencies, multiple power domains, and ...
Because of their high ESL compared to ceramic, tantalum capacitors are not the optimum choice for high frequency decoupling. Paralleling tantalum capacitors for bulk capacitance and ceramic for high ...
A capacitor rarely fails loudly. It fails quietly, and that’s what makes it dangerous. I remember debugging a compact PLC power board used in a packaging line. The system worked perfectly on the bench ...
