Ceramic Capacitor Value Range

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.

Ceramic capacitor value range.

Class 1 and class 2. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. By using this capacitor value calculator we can calculate the value of that capacitor or vice versa. Over time a series of standard capacitor values have evolved just as with resistors and inductors.

Characteristics precision and tolerances. The third character indicates the maximum amount of capacitance change over the part s temperature range. The second character indicates the maximum temperature. Capacitor values can be of over 10 9 range and even more as super capacitors are now being used.

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. 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. 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. 5 as in x5r corresponds to 85 c and 7 as in x7r corresponds to 125 c.

Ceramic capacitors encoding consists 1 3 digits. The theoretical range is from 45 c to 200 c. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. Common capacitor value with codes in a chart.

Encoding for ceramic capacitors. For code 104 the two figures 10 indicate the significant figures and the 4 indicates the multiplier i e. 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. 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.

The spec for r capacitors such as x5r and x7r is 15. Below table have all the common capacitor values listed that are useful for you. Whilst tantalum capacitors and electrolytic capacitors are used for the higher values over 1µf the ceramic capacitor dominates the market for values below 1µf. There are two classes of ceramic capacitors available today.

If the capacitor code consist only 1 or 2 digits it is simply their capacitance. For electrolytic capacitors simply capacitance values are written on them.
