Here is my complete conversion chart for all standard capacitor values. This chart allows one to convert between picofarads, nanofarads, and microfarads. With all the values listed here, you will not have any need to use a calculator. picofarads: nanofarads: microfarads: 1.0 pF: 0.0010 nF: 0.0000010 µF: 1.1 pF:
The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. In other words, …
The effect of the capacitor is called capacitance. The definition of capacitance is the electric charge Q divided by the voltage V, and it is represented as . C = Q/V: Where, ... In measuring instruments such as standard capacitors. #2 Ceramic Capacitors. In these capacitors, ceramic is used as a dielectric material. ...
The capacitance value of a capacitor is represented by the formula: where C is the capacitance, Q is the amount of charge stored, and V is the voltage between the two electrodes. ... Although most applications do not have to take the Q factor into serious consideration, and standard capacitors may be used in those applications, Q factor is …
Another rarely used CGS unit is statfarad (abbreviated statF) and it is equivalent to the capacitance of a capacitor with a charge of 1 statcoulomb across a potential difference of 1 statvolt. In terms of farad, it is 1.1126 x 10 -12 which is approximately 1.1126 picofarads.

The Significance of Tolerance in Capacitor Values Tolerance in capacitors indicates the permissible deviation of the actual capacitance from the stated nominal value, typically expressed as a percentage (e.g., ±10%, ±20%).
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …
Charge Stored in a Capacitor: If capacitance C and voltage V is known then the charge Q can be calculated by: Q = C V. Voltage of the Capacitor: And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known:. V = Q/C
Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by C 0 = ε 0 A d, C 0 = ε 0 A d,
Standard Capacitor Values - Electrolytic
Today, the capacitance, tolerance, and working voltage are printed on the body of the capacitors or indicated by BS1852 standard or BS EN 60062 standard codes. In these coding systems, the value, tolerance, and working voltage of the capacitor are indicated by two -or three-digit numerical codes followed by a letter.
Capacitors can act as filters on electric signals (as in the RC circuit) to create large pulses of currents and many more applications. The capacitance is the physical property used by capacitors to store charge. Geometric factors and fabrication details uniquely determine the capacitance of a device. We measure the capacitance in farads.

Natural capacitors have existed since prehistoric times. The most common example of natural capacitance are the static charges accumulated between clouds in the sky and the surface of the Earth, where the air between them serves as the dielectric. This results in bolts of lightning when the breakdown voltage of the air is exceeded.
Voltage coefficient of capacitance. Ceramic capacitors exhibit changes in capacitance with variations in DC bias level. Stated differently, measuring the capacitance of a device with a 1 V P-P size wave averaging 0 V will yield a different (typically greater) value than if the same device is tested with a 1 V sine wave having a DC offset of 10 V.
