Ceramic Disk Capacitor Markings

Two of the most common are shown here.

Ceramic disk capacitor markings.

Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. The example capacitor has a 3 digit number printed on it 103. When the first two numbers are multiplied with the multiplier the. The first two digits in this case the 10 give us the first part of the value.

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. Taking a look. This indicates a 22µf capacitor with a maximum voltage of 6v. A variety of schemes may be used.

This code indicates what the capacitance of the capacitor is. The letter j signifies the tolerance of 5. The third digit is the multiplier which is 1000. Method of finding the value meaning of codes of 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. Ceramic disc capacitors like the one on the left are printed with a code. There are several tolerance marking systems used. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter.

In addition to the capacitance value and possibly the working voltage or breakdown voltage the capacitor may be marked by its tolerance. 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. Typically the markings on a capacitor may give the figures like 22 and 6v.

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. The first is used with small ceramic capacitors and appears as a single letter. Read the tolerance code on ceramic capacitors.
