If the capacitor only has 1 digit the capacitance value is that 1 digit in picofarads.
Reading ceramic caps 2 digit.
47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.
It can t exceed more than 6.
Then by just using numbers and letters as codes.
The third digit will indicate a multiplier to be used on the base number to find the actual value of the capacitor.
Method of finding the value meaning of codes of capacitor.
The first two digits of printed code are the first two digits of capacitor value and the third digit gives the number of zeroes to be added so as to get capacitor value in pico farad.
If we calculate in nano farad for values ending with 4 then the reading becomes easy like 104 is 100 nf.
When the first two numbers are multiplied with the multiplier the.
Use a third digit of 0 through 5 to place the corresponding number of 0s behind the base value.
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.
This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor.
So the ceramic capacitor encoding system has 1 3 digits.
So for example if you simply see a 6 on the capacitor then this equals a value of 6 picofarads pf.
Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.
The 3 rd digit ranges between 0 6.
If 3 rd digit is 0 it means multiplier factor of 1.
For 3 digit s capacitor code the first two digits are the capacitance value in pf and the third digit is a multiplier factor of first two digits to calculate the final capacitance value of the capacitor.
Electrolytic ceramic and polyester we ll start with electrolytics as they are the most straightforward ones to read polyester and ceramic share the same labeling system but with some small differences.
The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.
A third digit of 8 means multiply the base value by 01.
If you have a capacitor that has nothing other than a three digit number printed on it the third digit represents the number of zeros to add to the end of the first two digits.
To make it a bit more difficult not all the capacitors share the same labeling system so we have to make a difference between the main 3 capacitor types.
The first two digits will indicate the base capacitor value in picofarads.
If the capacitor only has 2 digits the capacitance value are those 2 digits in picofarads.
The resulting number is the capacitance in pf.
