Which way to connect a capacitor?
Small ceramic capacitors do not have a polarity, so they can be mounten either way. Electrolitc capacitors have markings for the minus (- connection) most times there is a …
Practical Considerations
Here are some samples of different capacitor types, all smaller than the units shown previously: The electrolytic and tantalum capacitors are polarized (polarity sensitive), and are always …
Understanding Capacitor Types and Characteristics
The circuit model of a capacitor consists of a series resistive element representing the ohmic resistance of the conducting elements along with the dielectric resistance. This is called the equivalent, or effective, series …
Why decoupling capacitors used for power rails should be very …
For opamps (and other linear ICs like regulators) supply decoupling is needed also to keep the RF loops short but that has more to do with preventing oscillations and …
