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.

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 ...

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 ...

Tantalum capacitors provide high capacitance for a given size though they have higher ESL than ceramic and are, therefore, not the optimum choice for high frequency decoupling.

AVX has expanded the applications of its LICA series of low inductance decoupling capacitor arrays. Widely utilised in commercial and industrial five nines uptime applications, such as mainframe class ...

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 ...
