Reading Ceramic Capacitor Code

The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.

Reading ceramic capacitor code.

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. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. 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. Ceramic capacitor codes how to read a ceramic capacitor with numeric coding.

Method of finding the value meaning of codes of capacitor. Surface mount capacitors are often very small and do not have the space for markings. Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1. Then by just using numbers and letters as codes.

Smd ceramic capacitor codes. This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. Read the tolerance code on ceramic capacitors.

15 100 1500 pf. So this is how a capacitor value code calculator calculates the ceramic capacitor value from the capacitor code or vice versa. Similarly n51 indicates a 0 51nf or 510 pf capacitor etc. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. A variety of schemes may be used. The capacitance value will be calculated as follows.
