Ceramic capacitors are constructed with materials such as titanium acid barium used as the dielectric. Internally, these capacitors are not constructed as a coil, so they can be used in high frequency applications. Typically, they are used in circuits which bypass high frequency signals to ground.

These capacitors have the shape of a disk. Their capacitance is comparatively small.

  • The capacitor on the left is a 100pF capacitor with a diameter of about 3 mm.
  • The capacitor on the right side is printed with 103, so 10 x 103pF becomes 0.01 µF. The diameter of the disk is about 6 mm.
  • Ceramic capacitors have no polarity.
  • Ceramic capacitors should not be used for analog circuits, because they can distort the signal.
