Capacitor Code Chart Pdf
Ceramic disc capacitor code / label will normally consist of three numbers followed by a letter. They are very easy to decode to find the value. The first two significant digits represent the first two digits of the actual value, which is 47. The third digit is the multiplier, which is ×1000. The letter J signifies the tolerance of ±5 %. Since this is the EIA coding system, the value will be in pico farads. Hence the value of the capacitor above is 47000 pF ±5 %.
A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. If you are new to capacitor codes, then the best way to start is with a chart, because that way, you can see the arrangement of the code. Engineers usually do not require calculators because the code is so simple. Here is another example, code 104 is 10 followed by four zeros, hence 10 0000 pF. As you can see, it is so easy that you can do this in your head.
How to read Capacitor Codes Large capacitor have the value printed plainly on them, such as 10.uF (Ten Micro Farads) but smaller disk types along with plastic film types often have just 2 or three numbers on them?
How to read Capacitor Codes
Capacitor Code Information This table is designed to provide the value of alphanumeric coded ceramic, mylar and mica capacitors in general. They come in many sizes, shapes, values and ratings; many different manufacturers worldwide produce them and not all play by the same rules. How to Read a Capacitor. Unlike resistors, capacitors use a wide variety of codes to describe their characteristics. Physically small capacitors are especially difficult to read, due to the limited space available for printing. Capacitor uF - nF - pF Conversion Chart. When reading schematics, repairing radios and buying capacitors, you often must convert between uF, nF and pF. Paper and electrolytic capacitors are usually expressed in terms of uF (microfarads). Short forms for micro farad include. Displayed Capacitor Chart with Tantalum Capacitor Color Codes, Capacitor Code Guide, Mica Capacitor Values etc. Learn deeply about capacitor chart. The capacitor on the left is of a ceramic disc type capacitor that has the code 473J printed onto its body. Then the 4 = 1 st digit, the 7 = 2 nd digit, the 3 is the multiplier in pico-Farads, pF and the letter J is the tolerance and this translates to: 47pF. 1,000 (3 zero’s) = 47,000 pF, 47nF or 0.047uF the J indicates a tolerance of +/- 5%.

Here is a list of the currently available ceramic disc capacitors consisting of standard values. Large electronics suppliers will tend to stock all of these.
Voltage Code
The brown coloured ones usually have an underline below the marking, which means 50 V / 100 V. If there is no underline, then the rating is 500 V, assuming the manufacturer follows the marking scheme.
The epoxy-coated capacitors usually have the letters 1KV, which indicates 1000 V, and 2KV indicating 2000 V.
Sometimes capacitors do not have any markings regarding voltage rating and you have to look up the documentation of that component. However, manufacturers often use a combination of the above marking scheme.
Temperature Code
The black mark at the top of the disc represents the operating temperature range, which is approximately -25-°C to +85-°C.
Replacement
Ceramic disc capacitors come in many versions. For basic general applications, the brown ones are usually utilised for decoupling in low voltage circuits.
For switched-mode power supply applications, epoxy coated flame retardant capacitors are usually used. These meet the UL 94-V0 standard. They were originally utilised in the line-output stages of conventionalCRT based television sets.
