Every project will need a few decoupling capacitors; our mini web server project has three ICs that require a total of 11. This can be an expensive part to buy in singles, so it’s crucial to ...

C1 through-hole 0.1uF capacitor, such as Mouser #594-K104M15X7RF53L2, ($4 per 100 ) – This cheap 0.1uF capacitor will fit almost any design that calls for through-hole decoupling capacitors.

In “Know the sometimes-surprising interactions in modelling a capacitor-bypass network” (abbreviated to “Know the…” when referred to here), Tamara Schmitz of Intersil and I provided some simulation ...

Fig. 1: Decoupling capacitor hierarchy. The capacitors filtering the highest frequencies are in the chip itself, with additional ranks possible in the package, under the package on the PCB, and near ...

Specialized varieties of “super capacitors” are available with capacitance values exceeding a whole Farad, these are mainly used as battery substitutes, not bulk decoupling. Aluminum electrolytic ...

To add another wrinkle, don’t forget that every MCU vendor requires one or more decoupling capacitors, even when running from a battery. Generally they want one of about 10 uF. Be sure to use a ...

The 100% encapsulated SE4 metallized surface-mount power-supply decoupling capacitor series offers superior performance to unencapsulated polyphenylene-sulphide (PPS), polyester, and ceramic ...

Circuit 2: Adding supply ripple (with decoupling capacitor) Figure 3 shows a circuit that drives a 1MHz 200mVpp sinusoidal supply ripple across a 0.1μF decoupling capacitor. This circuit does not ...
