## How to know the Value of Capacitance of a Capacitor using Standard & Color Codes – Calculator & Examples

Same like the resistor color codes, there are special indications like bands, dots or points are printed on different types of capacitors which are used to show the value of capacitance of a capacitor, its voltage rating and tolerance etc. The use of different colors on a capacitor to show its values and characteristics is known as capacitor color coding.

Generally, the values of capacitance, voltage rating, tolerance and even the polarity (in case of polarized capacitor) are printed on the large size capacitor. On the other hand, for small capacitors like mica and ceramic capacitors, color codes are used to indicate their values (generally) in pF (picofarad).

The value of ceramic disk capacitors lower than 1000pf is printed on it in the form of digits and numbers. For example, the only number “300” is printed on a capacitor of 300pf.

Those capacitors having capacitance of 1000pf or more, their values can be read by the 3 digits numbers (e.g. 102. 103, 105 etc.) printed on it. These 3 digits color coding can be read as follows.

• 102 = 10 x 102 = 1000 pF (picofarad)
• 103 = 10 x 103 = 10,000 pF (picofarad)
• 105 = 10 x 105 = 1,000,000. pF (picofarad) = 1 μF (microfarad)

#### Reading Value of Large Cylindrical Capacitors (Polarized & Non-Polarized)

Generally, the overall rating is written and printed on these capacitors. For example

The fig 2 (a)

• The value of capacitance is 47 μF (microfarad).
• The value of maximum voltage this capacitor bears is 400V DC

The fig 2 (c)

• The value of capacitance is 1200 nF (nanofarad).
• The value of maximum bearable voltage is 500V.
• The value of tolerance is ± 5%. e.g. variation of capacitance in plus minus.

The fig 2 (c)

• The value of capacitance is 1200 μF (microfarad).
• The value of maximum voltage is 63 V DC.
• The value of tolerance is ± 20%.
• The value of temperature coefficient is -40 to +105°C.

The fig 2 (d)

We will show a solved example and table (see fig 3) below to show how to read the value of ceramic capacitors

• The value of capacitance is 0.01 μF (microfarad).
• The value of maximum voltage is “2G” (400V).
• The value of tolerance is “J” ± 5%.

For example, A DC capacitor can’t be operated at AC supply and vice versa until and unless mentioned in the user Manual. The VDC and VAC are mentioned on the capacitor rating nameplate with negative (-) sign for negative terminal on it.

The following symbols and units are used to represent the values of capacitance of capacitors in  Microfarad (μF), Nano-farad (nF) & Picofarad (pF).

#### Reading Value of Small Capacitors (Ceramic)

For small capacitors like ceramic, tantalum, film capacitors etc., the area is very small hence it is not possible to print the value of capacitance and voltage on it. This way, some special notations are used e.g. digits, numbers and alphanumeric characters which indicates the different characteristics and values of capacitors. Generally, the values of these capacitors are in pF (picofarad 1 x 10-9).

Let me show how to read the value of ceramic capacitors?

##### 2 Numerical Values:

If the ceramic capacitor has two numerical values, or any two digits and a letter like 33P, it means the value is 33 picofarad.

• If there is a letter in the middle of two digits like 6R2, it shows:

For example: 6R2 = 6.2 pF.

• If the first or middle letter is “μ”, “p” or “n” instead of R, it represents the main units of capacitance such as

For examples:

##### 3 Numerical Values:

Most of the ceramic capacitors have three numerical values printed on it. For example, 103, 104, 105 etc. Let’s see how to read these values. Suppose the printed value on the ceramic capacitor is “103”

• 103 = 10 x 103 = 10,000 pF (picofarad)

Similarly, if the specials marking code on the ceramic capacitor is 105:

• 105 = 10 + 5 Zeros = 1,000,000 pF
• = 1000 nF = 1 µF

Tolerance of Ceramic Capacitors

There are Capital letters printed on the ceramic capacitor except the value of capacitance such as 22M.

The following table shows the tolerance for ceramic capacitors indicated by Letters.

 Letters Tolerance in % A ±0.05 pF B ±0.1 pF C ±0.25 pF D ±0.5 pF E ±0.5% F ±1% G ±2% H ±3% J ±5 % K ±10% L ±15% M ±20% N ±30% P –0%, + 100% S –20%, + 50% W –0%, + 200% X –20%, + 40% Z –20%, + 80%

### Capacitor Color Codes

How to Read Capacitor Color Codes?

Except marking and alphanumeric codes, different color codes are also used to identify the value of a capacitor. These colored bands (on ceramic tubular capacitors) or dots ( on Mica capacitors) are printed on the outer surface of the capacitor.

The value of a capacitor having five color bands (or 5 dots) can be read using the following table.

In the following tables, the first three color bands show the value of capacitance, the fourth band as tolerance in percentage and the fifth band shows the temperature coefficient. For example:

• 1st Color Band = First Number of Value of Capacitor.
• 2nd Color Band = Second Number of value of Capacitor.
• 33rd Color Band = The number of Zeros (as multiplier) with the first two digits of capacitor (In numbers).
• 4th Color Band = Tolerance in percentage.
• 5th Color Band = Temperature coefficient.

Color codes for non-polarized mica molded and polyester capacitors like ceramic and disc capacitors are an old school method (BS-EN 60062) and hence replaced by the capacitor marking ( BS-1852 Standard) with alphanumeric codes. If you still find the old age color coded capacitor, you may identify the value of the ceramic capacitor using the following example (see fig 3(c) and 3(d).
