Tolerance specification: Together with the capacitor''s value, its tolerance indicates the likely variation from the stated nominal value—for example, 220pF ±10 %. Standard tolerances include ±5 % and ±10 %. Electrolytic capacitors typically have a larger tolerance range of up to ± 20%. Figure 2.
A collection of capacitors of comparable ratings is known as a capacitor bank. These capacitors are arranged in parallel or series sequence to gather electrical energy. A capacitor bank is usually applied to an AC source of power. This helps to rectify or compensate for power factor lag or phase shift.

Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.

A typical specification for an electrolytic capacitor states a lifetime of 2,000 hours at 85 °C, doubling for every 10 degrees lower temperature, achieving lifespan of approximately 15 years at room temperature. Supercapacitors also experience electrolyte evaporation over time. Estimation is similar to wet electrolytic capacitors.
A capacitor is one of the basic circuit components in electrical and electronic circuits. Capacitors are used to store energy in the form of an electrostatic field. Capacitors are available in several different types and sizes. Each type of capacitor has its unique characteristics and specifications that impact its performance.
