Capacitor code table

European capacitor material codes

FKC = metal foil and polycarbonate
FKP = metal foil and polypropylene
MKC = metallized polycarbonate foil
MKI = metallized polyphenylene sulphide
MKP = metallized polypropylene
MKS = polystyrene (metallized or with foil)
MKT = metallized polyester foil

Decoding capacitor codes

Looking at our capacitor we will see its marked 474J, this should be read as follows, 47 times the value that can be found in Table 1 corresponding to the 3rd number, in this case 10000. 47 * 10000 = 470000 pF = 470 nF = 0.47 uF with the J meaning a 5% tolerance. A second letter will be a temperature coefficient if its present. Judging by a capacitors size and type, you will quickly learn to determine if the value on the capacitor is given in pF, nF or uF.

If a capacitor is f.ex. marked 2A474J, the capacitance is decoded as described above, the two first signs is the voltage rating and can be decoded from table 2 here below. 2A is 100VDC rating according to the EIA standard.

Some capacitors are only marked 0.1 or 0.01, mostly in these cases the values are given in uF.

Some small capacitance capacitors can be marked with a R between numbers, f.ex. 3R9 where R is a indicator of values below 10pF and have nothing to do with resistance. 3R9 would be 3.9pF.

0G = 4.0VDC	0L = 5.5VDC	0J = 6.3VDC
1A = 10VDC	1C = 16VDC	1E = 25VDC
1H = 50VDC	1J = 63VDC	1K = 80VDC
2A = 100VDC	2Q = 110VDC	2B = 125VDC
2C = 160VDC	2Z = 180VDC	2D = 200VDC
2P = 220VDC	2E = 250VDC	2F = 315VDC
2V = 350VDC	2G = 400VDC	2W = 450VDC
2H = 500VDC	2J = 630VDC	3A = 1000VDC
