Ceramic Capacitor Value Range

The spec for r capacitors such as x5r and x7r is 15.

Ceramic capacitor value range.

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. Ceramic capacitors encoding consists 1 3 digits. By using this capacitor value calculator we can calculate the value of that capacitor or vice versa. Common capacitor value for smd capacitor is almost same as ceramic and electrolytic capacitors.

The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. If the capacitor code consist only 1 or 2 digits it is simply their capacitance. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. Whilst tantalum capacitors and electrolytic capacitors are used for the higher values over 1µf the ceramic capacitor dominates the market for values 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. There are two classes of ceramic capacitors available today. Capacitor values can be of over 10 9 range and even more as super capacitors are now being used. The theoretical range is from 45 c to 200 c.

Over time a series of standard capacitor values have evolved just as with resistors and inductors. 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. For electrolytic capacitors simply capacitance values are written on them. 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 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. Common capacitor value with codes in a chart. 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. 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.

For code 104 the two figures 10 indicate the significant figures and the 4 indicates the multiplier i e. Encoding for ceramic capacitors. 5 as in x5r corresponds to 85 c and 7 as in x7r corresponds to 125 c. The third character indicates the maximum amount of capacitance change over the part s temperature range.

Characteristics precision and tolerances. 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.
