Common capacitor value with codes in a chart.
Ceramic capacitor value range.
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.
Ceramic capacitors encoding consists 1 3 digits.
Common capacitor value for smd capacitor is almost same as ceramic and electrolytic capacitors.
Over time a series of standard capacitor values have evolved just as with resistors and inductors.
All capacitors have a tolerance rating that can range from 20 to as high as 80 for aluminium electrolytic s affecting its actual or real value.
Ceramic capacitors both as leaded devices and surface mount capacitors are available for values ranging from a few picofarads right up to values of just below 1µf.
Encoding for ceramic capacitors.
Capacitors are available in a huge range of package styles voltage and current handling capacities dielectric types quality factors and many other parameters still they largely hold to this range of values.
Below table have all the common capacitor values listed that are useful for you.
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.
Class 1 and class 2.
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 theoretical range is from 45 c to 200 c.
For code 104 the two figures 10 indicate the significant figures and the 4 indicates the multiplier i e.
The spec for r capacitors such as x5r and x7r is 15.
For electrolytic capacitors simply capacitance values are written on them.
The third character indicates the maximum amount of capacitance change over the part s temperature range.
By using this capacitor value calculator we can calculate the value of that capacitor or vice versa.
The two most common types are multi layer ceramic capacitors and ceramic disc capacitors.
The second character indicates the maximum temperature.
Characteristics precision and tolerances.
There are two classes of ceramic capacitors available today.
To prevent confusion with large numbers of zeros attached to the values of the different capacitors the common prefixes pico 10 12 nano 10 9 and micro 10 6 are widely used.
Smaller ceramic capacitors can have a nominal value as low as one pico farad 1pf while larger electrolytic s can have a nominal capacitance value of up to one farad 1f.
Capacitor values can be of over 10 9 range and even more as super capacitors are now being used.
5 as in x5r corresponds to 85 c and 7 as in x7r corresponds to 125 c.
