Reading Ceramic Capacitor Code

So this is how a capacitor value code calculator calculates the ceramic capacitor value from the capacitor code or vice versa.

Reading ceramic capacitor code.

A variety of schemes may be used. 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. When the first two numbers are multiplied with the multiplier the. Surface mount capacitors are often very small and do not have the space for markings.

Ceramic capacitor codes how to read a ceramic capacitor with numeric coding. Method of finding the value meaning of codes of capacitor. Similarly n51 indicates a 0 51nf or 510 pf capacitor etc. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.

Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be. Then by just using numbers and letters as codes. The capacitance value will be calculated as follows.

The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. 15 100 1500 pf. Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.

Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1. Read the tolerance code on ceramic capacitors. Often the value may be given in picofarads.
