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.
Reading ceramic caps 2 digit.
The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.
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.
If 3 rd digit is 0 it means multiplier factor of 1.
So the ceramic capacitor encoding system has 1 3 digits.
If the capacitor only has 2 digits the capacitance value are those 2 digits in picofarads.
The resulting number is the capacitance in pf.
If we calculate in nano farad for values ending with 4 then the reading becomes easy like 104 is 100 nf.
A third digit of 8 means multiply the base value by 01.
The first two digits will indicate the base capacitor value in picofarads.
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.
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.
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.
So for example if you simply see a 6 on the capacitor then this equals a value of 6 picofarads pf.
Many capacitor manufacturers use a shorthand notation to indicate capacitance on small caps.
When the first two numbers are multiplied with the multiplier the.
It can t exceed more than 6.
Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.
If the capacitor only has 1 digit the capacitance value is that 1 digit in picofarads.
The third digit will indicate a multiplier to be used on the base number to find the actual value of the capacitor.
Ceramic capacitors which are usually tiny pancakes with two pins typically list the tolerance value as one letter immediately after the three digit capacitance value.
The 3 rd digit ranges between 0 6.
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.
Method of finding the value meaning of codes of capacitor.
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.
