Maximal available capacitance values of MLCC Chips in case size 2012. (Status April 2017) Capacitance of MLCC chips depends on the dielectric, the size and the required voltage (rated voltage). Capacitance values start at about 1pF. The maximum capacitance value is determined by the production technique. For X7R that is 47 μF, for Y5V: 100 μF.
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.
Unpopulated hybrid circuit (Low Temperature Cofired Ceramics) Co-fired ceramic devices are monolithic, ceramic microelectronic devices where the entire ceramic support structure and any conductive, resistive, and dielectric materials are fired in a kiln at the same time.
105K 330V implies a capacitance of 10 × 10 5 pF = 1 μF (K = ±10%) with a working voltage of 330 V. 476M 100V implies a capacitance of 47 × 10 6 pF = 47 μF (M = ±20%) with a working voltage of 100 V. Capacitance, tolerance and date of manufacture can be indicated with a short code specified in IEC/EN 60062.
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 ...

Capacitance is the ability of an object to store electric charge. It is measured by the change in charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance.
