How to Choose a Bypass Capacitor Size
The current prefers to take the path of least resistance, which means if the bypass capacitor offers less resistance than the resistor, the goal of shunting AC signal to the ground can be achieved. Thus, the rule of thumb is that the value of a capacitor should be at least 10 times less than the value of R E, emitter resistance.

3.1: Resistors and Capacitors
Resistors. Resistors are two-terminal passive linear devices characterized by their resistance R [ohms]: [ mathrm{v}=mathrm{iR}] where v(t) and i(t) are the associated voltage and current. That is, one volt across a one-ohm resistor induces a one-ampere current through it; this defines the ohm.. The resistor illustrated in Figure 3.1.1 is …

Film capacitors use a thin plastic film as a dielectric.
Capacitor Basic Calculations
If the resistor was just 1,000 Ohms, the time constant would be 0.1 seconds, so it would take 0.5 seconds to reach 9V. If the capacitor was 1,000 microfarads it would take 50 seconds total. So as the capacitor size increases, the time taken increases. If the resistor value increases, the time taken also increases. Coming back to our original ...
Q factor | Fundamentals | Capacitor Guide
Good high-Q capacitors can have a Q factor value of over 10,000 at 1MHz and over 1,000 at 100MHz, while standard capacitors can have a Q factor as low as 50 at 1kHz. The difference between a high-Q capacitor and a standard capacitor is in the actual design of the capacitor, as as well as the materials used.

How to size a capacitor charging resistor?
$begingroup$ It''s worth looking at datasheets for a few different kinds of resistor. e.g. wire wound resistors tend to have much better pulse withstanding characteristics than thin- or thick-film chip resistors, even if you look at so-called "pulse-rated" chip resistors. $endgroup$ –
On-Chip Resistors and Capacitors
Off-chip discrete resistors and capacitors have high accuracy (typically 1% for resistors and 5% for capacitors), but they have to be used externally. This implies a higher cost and also raises other issues, like the number of pins that can be used to connect those external elements to the internal circuitry.
