For example if a ceramic capacitor has a code 5 and other has 47 their respective capacitance values are 5 pf and 47 pf.
Capacitor values ceramic.
Ceramic capacitors encoding consists 1 3 digits.
Ceramic capacitors are usually made with very small capacitance values typically between 1nf and 1µf although values up to 100µf are possible.
So the value is 10 with 3 extra zeros or 10 000 ceramic disc capacitor codes are always measured in pico farads or pf.
Common capacitor working voltages dc by capacitor type.
If the capacitor code consist only 1 or 2 digits it is simply their capacitance value in picofarads pf.
Generally capacitance of ceramic tantalum film capacitors is expressed in pico farad.
If the capacitor has two numerical values.
Some capacitors have letters in the second position and numerical value in first position.
Ceramic disc capacitor values code label.
The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications.
This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor.
Pico farads nano farads when lots of zeros need to be written to specify the capacitor value the capacitance can be given in nano farads nf where 1000 pf 1 nf.
They are not polarized which means that they may be safely connected to an ac source.
So it is a 10 000pf capacitor.
How to read ceramic capacitor values.
Ceramic capacitors are also very small in size and have a low maximum rated voltage.
The first two significant digits represent the first two digits of the actual value which is 47.
The numbering system is easy to use if you remember it is based on picofarads not microfarads.
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.
When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.
Ceramic disc capacitors have two to three digits code printed on them.
Encoding for ceramic capacitors.
Ceramic capacitors usually uses 3 digits like 102 103 101 for indicating their values and the values are in term of pico farad.
They are very easy to decode to find the value.
If the notation on the capacitor has 2 digits and a letter like 22m then it has capacitance value of 22.
