Ceramic Disk Capacitor Code

The capacitance value will be calculated as follows.

Ceramic disk capacitor code.

So this is how a capacitor value code calculator calculates the ceramic capacitor value from the capacitor code or vice versa. 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. Surface mount capacitors are often very small and do not have the space for markings.

The letter j signifies the tolerance of 5. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Ceramic disc capacitor values. I have always been unaware of the markings on a disc ceramic capacitor such as j m and other symbols.

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. Taking a look. Read the tolerance code on ceramic capacitors. Ceramic disc capacitor values.

Method of finding the value meaning of codes of capacitor. Smd ceramic capacitor codes. The first two significant digits represent the first two digits of the actual value which is 47. They are very easy to decode to find the value.

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 normally consists of a three digit number followed by a letter. Then by just using numbers and letters as codes. The third digit is the multiplier which is 1000.

The first two digits in this case the 10 give us the first part of the value. The example capacitor has a 3 digit number printed on it 103. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. 15 100 1500 pf.

It is very easy to decode to find the capacitor value. When the first two numbers are multiplied with the multiplier the. Ceramic capacitor codes how to read a ceramic capacitor with numeric coding. Ceramic disc capacitors like the one on the left are printed with a code.

An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block. The first two significant digits signify the first two digits of the actual capacitance value which is 47 the above capacitor. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor.

Similarly n51 indicates a 0 51nf or 510 pf capacitor etc. Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100. Often the value may be given in picofarads. 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.
