Electric Double Layered Capacitors , know as “Gold Capacitor”, offer the highest volumetric efficiency of all capacitor technologies. It is often compared to a secondary battery. Unlike batteries, the Gold Capacitor does not rely on a chemical reaction to produce electric current rather it is a storage cell that utilizes the absorption/release reaction of ions.

Compared to other capacitors and batteries,Gold Capacitors are very new. We have summarized the characteristics and reliability of Gold Capacitors in this manual. Suntan has developed the Gold Capacitor to meet your design needs. We hope you will find this manual informative and useful. Any requirements please visit www.suntan.com.hk.

The mica dielectric obviously forms the basis for silver mica capacitors. Its properties govern the performance of the silver mica capacitor. It was also one of the first dielectric materials to be used for capacitors in the early days or wireless because of its combination of stability and general physical and mechanical attributes.

For silver mica capacitors the silver electrodes are now plated directly on to the mica dielectric, although originally thin sheets of silver foil were placed between the mica dielectric. Again several layers are used to achieve the required capacitance. Wires for the connections are added and then the whole silver mica capacitor assembly is encapsulated to provide protection.

Varistor is one kinds of transient voltage suppression devices which can be used instead of transient suppression diodes, zener diode and capacitor combination. Varistor IC and other devices can protect the circuit, to prevent electrostatic discharge, surges and other transient current (such as lightning, etc.) the damage caused by them. Simply use varistors and connected to the protected circuit IC or device, when the voltage value above a certain moment, the varistor resistance decreased rapidly, conducting high current, thereby protecting the IC or electrical equipment; when the voltage is lower than the varistor voltage value, the varistor resistance high, almost open, and thus will not affect the device or the normal operation of electrical equipment.

 Ceramic capacitors are suitable for moderately high-frequency work (into the high hundreds of megahertz range, or, with great care, into the low gigahertz range), as modern ceramic caps are fairly non-inductive compared to the other major classes of capacitors (film and electrolytic). Capacitor technologies with higher self-resonant frequencies tend to be expensive and esoteric (typically, mica or glass capacitors).

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.
