Ceramic Disk Capacitor Markings

There are several tolerance marking systems used.

Ceramic disk capacitor markings.

Method of finding the value meaning of codes of capacitor. In addition to the capacitance value and possibly the working voltage or breakdown voltage the capacitor may be marked by its tolerance. The third digit is the multiplier which is 1000. This indicates a 22µf capacitor with a maximum voltage of 6v.

Typically the markings on a capacitor may give the figures like 22 and 6v. This code indicates what the capacitance of the capacitor is. The first is used with small ceramic capacitors and appears as a single letter. The first two significant digits represent the first two digits of the actual value which is 47.

Ceramic disc capacitors like the one on the left are printed with a code. The example capacitor has a 3 digit number printed on it 103. The letter j signifies the tolerance of 5. They are very easy to decode to find the value.

Two of the most common are shown here. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Taking a look.

Read the tolerance code on ceramic capacitors. The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block.

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. The first two digits in this case the 10 give us the first part of the value. When the first two numbers are multiplied with the multiplier the.
