Ceramic Capacitance Range

Ceramic capacitors which are available in the range of very small capacitance values pf and higher are already out of their smaller capacitance values suitable for higher frequencies up to several 100 mhz see formula above.

Ceramic capacitance range.

Ceramic capacitors are also very small in size and have a low maximum rated voltage. Ceramic disc capacitors have a capacitance value of about10pf to 100μf with a wide variety of voltage ratings between 16v to 15 kv and more. 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.

To gain higher capacitances these devices can be made from multiple layers. Tolerance 10 y5p 20 y5v voltage rating. 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 are well suited for high frequencies and high current pulse loads.

Because the thickness of the ceramic dielectric layer can be easily controlled and produced by the desired application voltage ceramic capacitors are available with rated voltages up to the 30 kv range. Class 3 ceramic capacitor dielectric. X7r dielectric chip usage covers the broad spectrum of industrial applications where known changes in capacitance due to applied voltages are acceptable. 10 0mmø unless otherwise states.

Popular class 2 ceramic dielectrics include x7r which as a temperature range of 55 to 125 c with a δc c0 of 15 y5v which as a temperature range of 30 to 85 c with a δc c0 of 22 82 and z5u which has a temperature range of 10 to 85 c and a δc c0 22 56. When converting between these it is sometimes useful to have a capacitor conversion chart or capacitor conversion table for the different capacitor values. Tecate s ceramic capacitors are available from sizes that can barely be seen with the naked eye to very large configurations that have multiple agency certifications and can be used in safety sensitive applications.
