How do smaller capacitors filter out higher frequencies than larger ...
Smaller-value capacitors have higher resonance points because they have lower ESL, making them better for high frequency bypassing. The construction of the cap can also reduce the ESL and thus improve high-frequency performance. Examples …

These capacitors can be either inductive or non-inductive. ... The bipolar nature and exceptional frequency characteristics make them popular in high-frequency circuits. In general, the typical capacitance value for these capacitors lies in between 1nF to 30muF.
A review of state-of-the-art and proposal for high frequency …
CMOS technology. However, in order to achieve high efficiency, capacitors must remain almost fully charged during operation as charging and discharging a capacitor is intrinsically lossy [36]. SC (Switched-Capacitor) convert-ers are then limited when there is a need to supply a high current as the required capacitors become too large. There
This is an example of a good frequency response for a resistor. For comparison, a wirewound resistor is only usable up to 50 kHz, because of both inductive and capacitive parasitic effects. Even when bifilar (non-inductive) winding methods are used, the inter-coil capacitance limits the maximum usable frequency.
The relationship between capacitive reactance and frequency is the exact opposite to that of inductive reactance, ( X L ) we saw in the previous tutorial. This means then that capacitive reactance is "inversely proportional to frequency" and has a high value at low frequencies and a low value at higher frequencies as shown.
When ESL is large, inductance components become dominant in high-frequency ranges, hindering the performance of capacitors. Another important characteristic is impedance. In short, …
Why does an inductor behave as a capacitor at high frequencies?
As the frequency increases, the impedance of the inductor increases while the impedance of the parasitic capacitor decreases, so at some high frequency the impedance of the capacitor is much lower than the impedance of the inductor, which means that your inductor behaves like a capacitor. The inductor also has its own …

Discrete capacitors deviate from the ideal capacitor. An ideal capacitor only stores and releases electrical energy, with no dissipation. Capacitor components have losses and parasitic inductive parts. These imperfections in material and construction can have positive implications such as linear frequency and temperature behavior in class 1 ceramic capacitors. Conversely…
Parasitic inductance usually manifests itself either in resistors with inferior properties such as helical wirewound resistors or in other resistors at very high frequencies. To demonstrate the high frequency problem, let''s examine a typical foil resistor of 220 Ω with an inductance of 0.05 μH operating at 1 GHz.

23.11 Reactance, Inductive and Capacitive – College Physics
If the frequency goes to zero (DC), tends to infinity, and the current is zero once the capacitor is charged. At very high frequencies, the capacitor''s reactance tends to zero—it has a negligible reactance and does not impede the current (it acts like a simple wire). Capacitors have the opposite effect on AC circuits that inductors have.
To prevent surge destruction, the wiring between the smoothing capacitor and the P & GND pins should be as short as possible. The use of a high-frequency non-inductive C3 capacitor of around 0.1 ~ 0.22 μF between the P & GND pins is recommended.

Capacitors favor change, whereas inductors oppose change. Capacitors impede low frequencies the most, since low frequency allows them time to become charged and stop the current. Capacitors can be used to filter out low frequencies. For example, a capacitor in series with a sound reproduction system rids it of the 60 Hz hum.
