In these devices, polystyrene film is used as the dielectric. This type of capacitor is not for use in high frequency circuits, because they are constructed like a coil inside. They are used well in filter circuits or timing circuits which run at several hundred KHz or less.

The component shown on the left has a red color due to the copper leaf used for the electrode. The silver color is due to the use of aluminum foil as the electrode.

  • The device on the left has a height of 10 mm, is 5 mm thick, and is rated 100pF.
  • The device in the middle has a height of 10 mm, 5.7 mm thickness, and is rated 1000pF.
  • The device on the right has a height of 24 mm, is 10 mm thick, and is rated 10000pF.
  • These devices have no polarity.
