There are several types of bypass capacitors
"two bypass/decoupling capacitors" rule?
Real capacitors have inductance and resistance. The objective of a bypass capacitor is to rapidly respond to current transients in order to maintain a stable voltage. The series inductance and resistance are counter to that goal. simulate this circuit – Schematic created using CircuitLab ...

What is the difference between Coupling, Decoupling, and Bypass Capacitors…
Hence, decoupling capacitors are also called bypass capacitors. In the above discussion of decoupling capacitors, we have learned how bypass capacitors route the noise to ground from power sources. Bypass capacitors can also be used in other sections of a circuit to filter out noise and improve the overall performance of the circuit.

Where C BIAS is the nominal capacitance at the operating voltage; TVAR is the worst-case capacitance variation over temperature (as a fraction of 1); TOL is the worst-case component tolerance (as a fraction of 1). In this example, TVAR is 15% from –40 C to +85 C for an X5R dielectric; TOL is 10%; C BIAS is 0.94 µF at 1.8 V, as shown in …

What is a Bypass Capacitor?
Now that you know conceptually what a bypass capacitor is, the next step is to know how to select the value of the bypass capacitor. And selecting the value is pretty straightforward. The value of the bypass capacitor should be at least 1/10th of the resistance across the emitter resistance, R E at the lowest frequency intended to be …
Basic Introduction to the Types of Capacitors
A variety of capacitors are used in the manufacture of electronic devices, and they play different roles in the circuit. There are many types of capacitors, such as fixed capacitors, variable capacitors, and trimmer capacitors, and fixed capacitors can be divided into ceramics, mica, paper, film, and electrolytic capacitors according to the …
Clean Power for Every IC, Part 1: Understanding Bypass Capacitors …
First, though, a brief note about terminology: The components discussed in this article are regularly referred to as both "bypass capacitors" and "decoupling capacitors." There is a subtle distinction here—"decoupling" refers to …
Clean Power for Every IC, Part 2: Choosing and Using Your Bypass Capacitors …
And this, in turn, demonstrates why the exact capacitance of a bypass capacitor is not particularly important: as long as the capacitor can store enough charge, the capacitance value is acceptable. It turns out that 0.1 µF is a convenient value, but 1 µF or even 0.01 µF might be equally appropriate in terms of capacitance .
