Ceramic Capacitor may have 3 or 4 numbers at its body.
Last number is multiplier.
The number tells how much =zeros= contains multiplied number.
Numbers before are value in pF.
Example 1:
At a capacitor’s body is number 102.
It means 10pF multiply to 100 (last number tells us about 2 =zeros=).
So, 1000pF.
Example 2.
At a capacitor’s body is number 101.
It means 10pF multiply to 10 (last number tells us about 1 =zero=).
So, 100pF.
Example 3:
At a capacitor’s body is number 103.
It means 10pF multiply to 1000 (last number tells us about 3
=zeros=). So, 10000pF.
Capacitor that has value in pF may be marked straight
away in pF. A letter =p= shows the value.
Example 4:
At a capacitor’s body is number 5p6. It means 5.6pF.
Example 5:
At a capacitor’s body is number 10p. It means 10pF.
Sometimes, capacitance is marked in 1000pF. Letter
=n= tells about it.
Example 6:
At a capacitor’s body is number 2n2. It means 2200pF.

Example 7:
At a capacitor’s body is number 10n. It means 10000pF.
Capacitance may be marked in μF.
At the case only numbers with point can be found at the body.
Example 7:
At a capacitor’s body is number = .1=. It means 0.1 μF.
Example 8:
At a capacitor’s body is number = 3.3=. It means 3.3 μF.
As usual, after numbers follows a letter. The letter
may be located under numbers. The letter tells us about tolerance.
Table 1 shows the tolerance code.
Example 9: At
a capacitor’s body is number 103N. It means 10pF multiply to
1000 (last number tells us about 3 =zeros=). So, 10000pF + 30%.
Example 10: At
a capacitor’s body is number 2p2B. It means 2.2pF + 0.1pF.
Some capacitors may have mark of Temperature Coefficient which
is marked by different color at cap of the capacitor. Table
2 shows the Color Code for a Temperature
Coefficient.
Example 11:
At a capacitor’s body is number 101.
Cap is red. It means 100pF N080.
Some old capacitors may have Letter Code for dielectric
material. Table 3
shows the code.
