Nominal capacitance and Recognition

As the capacitor volume than the resistance, it is generally nominal direct method.

If it is 10n, then that is 10nF, the same 100p is 100pF. If 4n7 is a direct representation 4.7nF not standard units: with 1 to 4 digits that identify the index, capacity unit is pF, such as monolithic ceramic capacitors, and some, generally exponential form, on behalf of 47 × 471 10 ^ 1 pF = 470pF.

Ceramic capacitors also have a direct identification capacity, the unit is pF.

Tantalum capacitors, generally direct identification number, common unit Cuo F.

Color-coded notation: capacitance wire direction along with different colors represent different figures, first, two ring represents capacity, a third color represents a valid number after the number of zeros (in pF)

Color meaning: black = 0, brown = 1, red = 2, orange = 3, 4 = yellow, green = 5, 6 blue = purple = 7, gray = 8 white = 9.

Recognition capacitor: see it above nominal, generally indicated capacity and the positive and negative, such as tantalum capacitors, one end of the white line is positive, the other like electrolytic capacitors, use pin to distinguish positive and negative long length feet positive, negative short leg.

Capacitance calculation method is this:
AX represents A (General digits) multiplied by the x th pF 10, so 104 is 0.1uF.
Representation of the resistance is the same.
The resistor 103 represents 10,000 ohms, ie 10K, 102 is 1K.
Some capacitance numeral 474, it means that 0.47uF plus some.
