If instead, we were to use one large capacitor rather than many small identical capacitors, we would have one self-resonance at low frequency. This can be very undesirable for digital signals, which would see inductive impedance at high frequencies in such a situation, and would lead to large voltage swings when the IC switches. ... The …

MIM/MOM capacitor extraction boosts analog and RF designs
A MIM capacitor consists of parallel plates formed by two metal planes separated by a thin dielectric [11]. MIM capacitors are used in RF circuits for oscillators, phase-shift networks, coupling, and bypass capacitance. They are also useful for analog design, due to their highly linear nature and dynamic range [5].

Top 4 Car Audio Capacitors For A Smooth Listening Experience
To put it very simply, audio capacitors are secondary reserves that can store large quantities of electrical power. Hence, when demanding car components like amplifiers need a ton of power, they can draw from this reserve without straining the car''s battery. Unlike car batteries, capacitors have rather minimal internal resistance.
