Ceramic Disk Capacitor 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.

Ceramic disk capacitor code. Ceramic disc capacitor code normally consists of a three digit number followed by a letter. 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 capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. 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. It is very easy to decode to find the capacitor value. Similarly n51 indicates a 0 51nf or 510 pf capacitor etc.

Ceramic disc capacitor values. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. The first two significant digits represent the first two digits of the actual value which is 47. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.

This code indicates what the capacitance of the capacitor is. Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100. Surface mount capacitors are often very small and do not have the space for markings. The example capacitor has a 3 digit number printed on it 103.

Read the tolerance code on ceramic capacitors. The capacitance value will be calculated as follows. 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. Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1.

The third digit is the multiplier which is 1000. Method of finding the value meaning of codes of capacitor. 15 100 1500 pf. Ceramic disc capacitor values.

They are very easy to decode to find the value. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. 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.

So this is how a capacitor value code calculator calculates the ceramic capacitor value from the capacitor code or vice versa. Taking a look. A variety of schemes may be used. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

Then by just using numbers and letters as codes. The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s. Smd ceramic capacitor codes. Often the value may be given in picofarads.
