This "multi-layer ceramic capacitor" (MLCC) was compact and offered high-capacitance capacitors. [3] The production of these capacitors using the tape casting and ceramic-electrode cofiring processes was a great manufacturing challenge. MLCCs expanded the range of applications to those requiring larger capacitance values in smaller cases.
The capacitance increases with the area A of the plates and with the permittivity ε of the dielectric material, and decreases with the plate separation distance d. The capacitance is therefore greatest in devices made from materials with a high permittivity, large plate area, and small distance between plates.
Electrolytic capacitors offer very high capacitance but suffer from poor tolerances, high instability, gradual loss of capacitance especially when subjected to heat, and high leakage current. Poor quality capacitors may leak electrolyte, which is harmful to printed circuit boards. The conductivity of the electrolyte drops at low temperatures ...

Greater capacitance per volume, since there are no airgaps between plates and mica, the conducting surfaces can be thinner. No clamping mechanism is needed. They are sometimes informally referred to as mica capacitors. Any modern reference to mica capacitors can be assumed to mean these, unless pre-World War II equipment is being discussed.
The capacitance value measured at the frequency of 1 kHz is about 10% less than the 100/120 Hz value. Therefore, the capacitance values of polymer e-caps are not directly comparable and differ from those of film capacitors or ceramic capacitors, whose capacitance is measured at 1 kHz or higher.
The challenge of custom IPDs compared to standard integrated or discrete passives however is the availability time for the assembly and sometimes also the performance. Depending on the manufacturing technology of integrated passives high capacitance or resistor values with a required tolerance may be hard to meet.
Schematic illustration of a supercapacitor [1] A diagram that shows a hierarchical classification of supercapacitors and capacitors of related types. A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits.
