Ceramic disc capacitors like the one on the left are printed with a code.
Ceramic disk capacitor code.
When the first two numbers are multiplied with the multiplier the.
The first two significant digits signify the first two digits of the actual capacitance value which is 47 the above capacitor.
47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.
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.
Similarly n51 indicates a 0 51nf or 510 pf capacitor etc.
They are very easy to decode to find the value.
Ceramic disc capacitor values.
The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.
Surface mount capacitors are often very small and do not have the space for markings.
So this is how a capacitor value code calculator calculates the ceramic capacitor value from the capacitor code or vice versa.
Smd ceramic capacitor codes.
Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100.
15 100 1500 pf.
The capacitance value will be calculated as follows.
Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor.
Ceramic capacitor codes how to read a ceramic capacitor with numeric coding.
Ceramic disc capacitor code label will normally consist of three numbers followed by a letter.
The example capacitor has a 3 digit number printed on it 103.
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.
Often the value may be given in picofarads.
Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.
Then by just using numbers and letters as codes.
It is very easy to decode to find the capacitor value.
The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
The first two digits in this case the 10 give us the first part of the value.
The third digit is the multiplier which is 1000.
This code indicates what the capacitance of the capacitor is.
Method of finding the value meaning of codes of capacitor.
Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1.
Taking a look.
Ceramic disc capacitor code normally consists of a three digit number followed by a letter.
The letter j signifies the tolerance of 5.
The first two significant digits represent the first two digits of the actual value which is 47.
The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s.
A variety of schemes may be used.
I have always been unaware of the markings on a disc ceramic capacitor such as j m and other symbols.
