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.

The tantalum capacitor is a highly reliable type of solid capacitor or electrolytic capacitor. Surface mount tantalum capacitors are increasingly being used in circuit designs because of their volumetric efficiency, basic reliability and process compatibility.

Tantalum capacitors are manufactured from a powder of relatively pure tantalum metal. The typical particle size is between 2 and 10 μm. Surface area is expressed in capacitance (C) in microfarads (µF) times voltage (V) in volts (V) per gram of powder (CV/g) Note the very great difference in particle size between the powders.

Our Suntan Technology Company has many types of tantalum capacitors ,such as Dipped Tantalum Capacitor-TS19,Please see the detailed information on our websitewww.suntan.com.hk for your reference ,and welcome your enquiry about our all kinds of capacitors.

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.

 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).
