The base unit of the capacitance representation method for capacitors is pf, and the international standard unit of capacitance is F. These two viewpoints need to be clarified first. Secondly, the operation of 104 is 10 times the fourth power of 10, and the final result is in pf. The result is 100000 pf, which is converted to uf and is 0.1 uf. This capacitance value is the most commonly used capacitance value in design.

The statistics are as follows:

1F (Farad)=1000mF (Millimeter Method), 1 (Millimeter Method)=1000uF (Micro Method), 1 (Micro Method)=1000nF (Nano Method), 1 (Nano Method)=1000pF (Pi Method).

Rule: Omitted units are represented as pF, for example

101 (pF)=10 * 10 ^ 1=100pF=0.1nF;

104 (pF)=10 * 10 ^ 4=100000pF=0.1uF;

105 (pF)=10 * 10 ^ 5=1000000pF=1uF.

Capacitance is also called "capacitance", which refers to the charge storage under a given potential difference, recorded as C, and the International unit is Farad (F). Generally speaking, charges move under force in an electric field. When there is a medium between conductors, it hinders the movement of charges and causes them to accumulate on the conductor, resulting in the accumulation and storage of charges. The amount of stored charges is called capacitance.

Capacitance refers to the ability to accommodate an electric field. Any electrostatic field is composed of many capacitors, and if there is an electrostatic field, there is a capacitor, which is described by an electrostatic field. It is generally believed that an isolated conductor forms a capacitance with infinity, and a conductor grounded is equivalent to being connected to infinity and connected to the earth as a whole.

Capacitance (or electrical capacity) is a physical quantity that represents the ability of a capacitor to hold charges. Physically speaking, capacitors are a static charge storage medium that may have permanent charges, which is their characteristic. They have a wide range of applications and are indispensable electronic components in the fields of electronics and power. Mainly used in power filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, DC isolation and other circuits.
