Capacitor capacity representation(II)

Digital representation:

The digital representation of the capacitor is usually used to represent the size of the capacity in three digits. The unit is pF. The two digits in the front represent the effective number of the capacitance value. The third digit number indicates the number of zero after the effective number (that is, multiplied by 10X, and X is third bits). If the third digit is represented by "9", it means that the capacitance of the capacitor is between 1 and 9.9 pF, and this "9" is 10-1. For example, 223 is 22 x 103 (pF) =22000 pF=0.022 mu F. Another 339 is 33 * 10-1 (pF) =3.3 pF. Digital representation is the most common method in capacitors.

Color ring representation:

The color code representation is similar to the digital representation. The difference is that it is not a number, but a color that represents a number. Color black, brown, red, orange, yellow, green, blue, violet, ash and white represent 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9, respectively. Along the direction of the lead, the number represented by the first, second colors represents the effective number of the capacity, and the number represented by the third colors represents the "0" number added after the effective number, and its unit is pF. If the color of the first color ring is brown, the color of the second color ring is black, and the color of the third color ring is yellow, the number of the first color ring is 104, or 0.1 F.
