Ceramic Disk Capacitor Code

A variety of schemes may be used.

Ceramic disk capacitor code.

The first two digits in this case the 10 give us the first part of the value. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. So this is how a capacitor value code calculator calculates the ceramic capacitor value from the capacitor code or vice versa. I have always been unaware of the markings on a disc ceramic capacitor such as j m and other symbols.

They are very easy to decode to find the value. The example capacitor has a 3 digit number printed on it 103. Taking a look. The third digit is the multiplier which is 1000.

Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100. Ceramic disc capacitor values. Ceramic disc capacitors like the one on the left are printed with a code. Ceramic capacitor codes how to read a ceramic capacitor with numeric coding.

The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s. The capacitance value will be calculated as follows. Similarly n51 indicates a 0 51nf or 510 pf capacitor etc. The first two significant digits represent the first two digits of the actual value which is 47.

Often the value may be given in picofarads. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. Method of finding the value meaning of codes of capacitor. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.

An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block. Read the tolerance code on ceramic capacitors. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. When the first two numbers are multiplied with the multiplier the.

Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1. 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 capacitor values. Smd ceramic capacitor codes.

Ceramic disc capacitor code normally consists of a three digit number followed by a letter. The letter j signifies the tolerance of 5. 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. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor.

15 100 1500 pf. Then by just using numbers and letters as codes. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. This code indicates what the capacitance of the capacitor is.
