ceramic

Ceramic capacitors use ceramic as the dielectric. They can have a large value of capacitance for a small size. There is no polarity with ceramics, this means that it can be used in AC circuits. Values can be made in a range from 1pF to 100μF. They can be made to operate at DC voltages from 10 – 5000 V. Many uses: coupling, bypassing and blocking. Disadvnatage is that high value capacitances is not possible.
