Multilayer ceramic capacitors are available in a variety of physical sizes and configurations, including leaded devices and surface mounted chips. Leaded styles include molded and conformally coated parts with axial and radial leads. However, the basic capacitor element is similar for all styles. It is called a chip and consists of formulated dielectric materials which have been cast into thin layers, interspersed with metal electrodes alternately exposed on opposite edges of the laminated structure. The entire structure is fired at high temperature to produce a monolithic block which provides high capacitance values in a small physical volume. After firing, conductive terminations are applied to opposite ends of the chip to make contact with the exposed electrodes. Termination materials and methods vary depending on the intended use.

Suntan TS17 Axial Multilayer Ceramic Capacitor, it can be made 50VDC and 100VDC, from 100pF to 1uF. The leads can be bended for mounting purpose.

Multilayer (mono) Axial & Radial Features:

Wide application in computer, data processor, telecommunication, Industrial control, and instrumentation equipments, etc.

Built by superior moisture and shock resistant epoxy coating, can be supplied in both bulk or tape and reel package for automatic insertion in printed circuit board.

Multilayer varistor (MLV) devices provide electrostatic discharge protection to electronic circuits from low to medium energy transients in sensitive equipment operating at 0-120 volts dc. They have peak current ratings from about 20 to 500 amperes, and peak energy ratings from 0.05 to 2.5 joules.

Suntan is with very good support for Multilayer Metal Oxide Chip Varistor. This products is featured with Low firing, Sliver diffusion, Grain resistance, Electrical properties and it is widely used in cellular telephones and automotive electronic subassemblies.

This type of capacitor is a essentially a form of polyester film capacitor where the polyester films themselves are metallised. The advantage of using this process is that because their electrodes are thin, the overall capacitor can be contained within a relatively small package. The metallised polyester film capacitors are generally only available as leaded electronics components.

Suntan is a Hong Kong based manufacturer of Plastic Film Capacitors, Its Metallised Polyester Film Capacitor is NON-INDUCTIVE, EXTENDED FOIL, DIP COATED, HIGH MOISTURE RESISTANCE, Such as their TS02 .TS02 has three features:

1.High reliable with its Self-Healing performance.

2.Coated with epoxy resin for superior heat resistance, humidity resistance and solvent resistance.

3.Good reputation in use with filtering, DC blocking coupling and general communication equipment.

In Suntan’s website: www.suntan.com.hk there is all TS series Capacitors. Detailed Features & Specifications & PDF will give you a new knowledge of Electrical Capacitors.

An electric double-layer capacitor, also known as supercapacitor, supercondenser, pseudocapacitor, electrochemical double layer capacitor (EDLC), or ultracapacitor, is an electrochemical capacitor with relatively high energy density, typically on the order of thousands of times greater than an electrolytic capacitor. For instance, a typical D-cell sized electrolytic capacitor displays capacitance in the range of tens of millifarads. The same size electric double-layer capacitor might reach several farads, an improvement of two orders of magnitude. Supercapacitors usually yield a lower working voltage. as of 2010 larger double-layer capacitors have capacities up to 5,000 farads. Also in 2010, the highest available supercapacitor energy density is 30 Wh/kg, (although 85 Wh/kg has been achieved at room temperature in the lab ) lower than rapid-charging lithium-titanate batteries.

Suntan is a Hong Kong based manufacturer of Gold Capacitors. Including Low Leakage Double Layer Capacitor, Stacked Coin Gold Capacitor and Serial Struction Gold Capacitor etc.

Electric Double-Layer Capacitor is Small-size, large capacity, excellent voltage holding. For all ratings, uniform 5 mm pitch of terminal spacing. Wider temperature range(-25~+70℃) thank battery makes periodic change unnecessary.13.5x7.5 size can encase up to 0.33F. Ideal for backing up of CMOS's, microcomputers, RAM's and the like used in VCR's, tuners, TV sets, telephone sets and other.

SMD ceramic capacitors are shaped in the form of a rectangular block or cuboid. The capacitor itself consists of the ceramic dielectric in which a number of interleaved precious metal electrodes are contained. This structure gives rise to a high capacitance per unit volume. The inner electrodes are connected to the two terminations, either by silver palladium (AgPd) alloy in the ratio 65 : 35, or silver dipped with a barrier layer of plated nickel and finally covered with a layer of plated tin (NiSn).

Suntan supply many kinds of Ceramic Capacitors such as High Voltage Ceramic Capacitors, Multilayer Ceramic Capacitors, Ceramic Disc Capacitors, Mini Type Ceramic Capacitors etc.

The service life of an aluminum electrolytic capacitor for mid- to high-voltage filters is affected by the applied voltage. If the applied voltage is between 60% and 100% of the rated voltage, the estimated service can be extended by lowering the applied voltage below the rated voltage. However, if the applied voltage is less than 60% of the rated voltage or the capacitor is used in low-pressure (100 WV or less) applications, the impact of the applied voltage on the service life is negligible.

Therefore, service life is estimated assuming no impact from voltage. Continuous application of a voltage over the rated voltage rapidly increases leakage current in a capacitor. This may increase internal pressure due to generation of gases, resulting in activation of the safety vent in a short time and/or formation of an internal short circuit. For this reason, the applied voltage must be maintained below the rated voltage during use.

Besides, it should be noted that the circuit design is such that the applied voltage will remain 80% or less of the rated voltage during use.

Where more than one capacitor connected in series is used, the applied voltages across the individual capacitors may become out of balance, resulting in the application of excessive voltage to them. To avoid this, either choose a rated voltage allowing for voltage imbalances, or connect a voltage divider(resistors) to the capacitors. Please be careful about charge/discharge.

Any three-terminal potentiometer can be used as a two-terminal variable resistor by not connecting to the third terminal. It is common practice to connect the wiper terminal to the unused end of the resistance track to reduce the amount of resistance variation caused by dirt on the track.
