Ceramic Disk Capacitor Code

It is very easy to decode to find the capacitor value.

Ceramic disk capacitor code.

Ceramic disc capacitor values. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. Then by just using numbers and letters as codes. They are very easy to decode to find the value.

Taking a look. 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 letter j signifies the tolerance of 5. So this is how a capacitor value code calculator calculates the ceramic capacitor value from the capacitor code or vice versa.

The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Read the tolerance code on ceramic capacitors. When the first two numbers are multiplied with the multiplier the. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter.

Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100. Ceramic capacitor codes how to read a ceramic capacitor with numeric coding. Often the value may be given in picofarads. Method of finding the value meaning of codes of capacitor.

Ceramic disc capacitor code normally consists of a three digit number followed by a letter. This code indicates what the capacitance of the capacitor is. I have always been unaware of the markings on a disc ceramic capacitor such as j m and other symbols. Similarly n51 indicates a 0 51nf or 510 pf capacitor etc.

The first two significant digits signify the first two digits of the actual capacitance value which is 47 the above capacitor. A variety of schemes may be used. Ceramic disc capacitor values. 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.

Smd ceramic capacitor codes. The capacitance value will be calculated as follows. Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1. 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 digits in this case the 10 give us the first part of the value. Ceramic disc capacitors like the one on the left are printed with a code. The third digit is the multiplier which is 1000. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. The example capacitor has a 3 digit number printed on it 103. 15 100 1500 pf. The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s.
