capacitor, hold the capacitor so that the three arrows point to

the right (>). The first dot at the base of the arrow sequence

(the leftmost dot) represents the capacitor TYPE. This dot is

either black, white, silver, or the same color as the capacitor

body. Mica is represented by a black or white dot, and paper by

a silver dot or a dot having the same color as the body of the

capacitor. The two dots to the immediate right of the type dot

The dot at the bottom right represents the multiplier to be

used. The multiplier represents picofarads. The dot in the

bottom center indicates the tolerance value of the capacitor.

Let's assume that, we have a capacitor in our hand. To read

this capacitor, first, turn the capacitor so that the arrows (>)

are pointing from left to right. Read the first dot, which in

this case is white. Looking at the chart in figure 47, on the

previous page, we see that white indicates a mica capacitor.

Now read the first digit dot (or second dot) the second dot is

brown. Referring to the chart in figure 47, we see that brown

indicates 1. Then read the second digit dot, which in this case

is red. Looking at the chart, we see that red indicates a value

of 2. This gives us, thus far, 12. Now read the multiplier

dot, which is at the bottom righthand side of the capacitor.

Remember that the multiplier is in picofarads. In this case,

the multiplier dot is also red. Looking at the chart., we see

that red indicates a multiplier of 100. Now multiply the

multiplier by the first two digits (100 x 12 = 1200 picofarads).

Finally, read the last dot, which is the tolerance dot. In our

(example, the tolerance dot is blue. Looking at the chart, we

see that blue indicates a tolerance of + 2%.

According to the above coding, the capacitor is a mica capacitor

whose capacitance is 1200 picofarads with a tolerance of 2%.

The capacitor shown in figure 48, on the following page, is a

tubular capacitor. Because this type of capacitor always has a

paper dielectric, the type of code is omitted. To read the

code, hold the capacitor so that the band closest to the end is

on the left side then read left to right. The last two bands

(the fifth and sixth bands from the left) represent the voltage

rating of the capacitor.
