Long life, with little degradation over hundreds of thousands of charge cycles. Due to the capacitor's high number of charge-discharge cycles (millions or more compared to 200 to 1000 for most commercially available rechargeable batteries) it will last for the entire lifetime of most devices, which makes the device environmentally friendly. Rechargeable batteries wear out typically over a few years, and their highly reactive chemical electrolytes present a disposal and safety hazard. Battery lifetime can be optimised by only charging under favorable conditions, at an ideal rate and, for some chemistries, as infrequently as possible. Electric Double Layer Capacitor can help in conjunction with batteries by acting as a charge conditioner, storing energy from other sources for load balancing purposes and then using any excess energy to charge the batteries at a suitable time.

Electric Double Layer Capacitor do not have a conventional dielectric. Rather than two separate plates separated by an intervening substance, these capacitors use "plates" that are in fact two layers of the same substrate, and their electrical properties, the so-called "electrical double layer", result in the effective separation of charge despite the vanishingly thin (on the order of nanometers) physical separation of the layers. The lack of need for a bulky layer of dielectric permits the packing of plates with much larger surface area into a given size, resulting in high capacitances in practical-sized packages.

In an electrical double layer, each layer by itself is quite conductive, but the physics at the interface where the layers are effectively in contact means that no significant current can flow between the layers. However, the double layer can withstand only a low voltage, which means that electric double-layer capacitors rated for higher voltages must be made of matched series-connected individual Electric Double Layer Capacitor, much like series-connected cells in higher-voltage batteries.

Electric Double Layer Capacitor have much higher power density than batteries. Power density combines the energy density with the speed that the energy can be delivered to the load. Batteries, which are based on the movement of charge carriers in a liquid electrolyte, have relatively slow charge and discharge times. Capacitors, on the other hand, can be charged or discharged at a rate that is typically limited by current heating of the electrodes. So while existing Electric Double Layer Capacitor have energy densities that are perhaps 1/10th that of a conventional battery, their power density is generally 10 to 100 times as great (see diagram, right).

Mica capacitors are currently used in some low power RF designs, and pulse (snubber) applications, but advances in ceramic capacitor performance have slowly eroded mica’s traditional edge in these areas over the years. Perhaps more importantly, mica capacitors tend to be bulky—a result of the relatively low dielectric constant. For example, a 300 pF dipped mica capacitor may be as much as 16 times larger (in volume) than a good 300 pF MLC (NPO) capacitor. This low volumetric efficiency is a serious drawback in many applications such as portable electronic equipment. Some chip mica capacitors are available, but they tend to be expensive. Mica capacitors are still indispensable in high-power RF transmitter applications. In the latter case special rectangular, cylindrical, and button-style cases are used. Another niche is high-voltage applications that are a result of mica’s high dielectric breakdown and corona resistance.

Suntan Silver Mica Capacitors are available with values that range from 1–22,000 pF, voltages are in the range 50–1000V for standard dipped mica capacitors. Mica capacitors exhibit very little voltage dependence, have high Q or conversely small power factors that are quite independent of frequency. With all these advantage, our mica capacitors are ideal for high requence and RF applications.

Tantalum capacitors are a particularly useful form of capacitor. They offer a high capacity density, and provided they are operated within their ratings, they offer a high degree of reliability. Also they lend themselves to surface mount technology and in this guise tantalum capacitors are used in vast quantities each day.

Suntan provides Chip Tantalum Capacitor SMD—TS20, This type of capacitor is with 6 different sizes ( P case, A case, B Case, C case, D case, E Case ).

An electrolytic capacitor is a type of capacitor that uses an electrolyte, an ionic conducting liquid, as one of its plates, to achieve a larger capacitance per unit volume than other types. They are often referred to in electronics usage simply as "electrolytics". They are used in relatively high-current and low-frequency electrical circuits, particularly in power supply filters, where they store charge needed to moderate output voltage and current fluctuations in rectifier output. They are also widely used as coupling capacitors in circuits where AC should be conducted but DC should not. There are two types of electrolytics; aluminum and tantalum.

A common modeling circuit for an electrolytic capacitor has the following schematic:

Where Rleakage is the leakage resistance, RESR is the equivalent series resistance (ESR), LESL the equivalent series inductance (L being the conventional symbol for inductance).

RESR must be as small as possible since it determines the loss power when the capacitor is used to smooth voltage. Loss power scales quadratically with the ripple current flowing through and linearly with RESR. Low ESR capacitors are imperative for high efficiencies in power supplies. Low ESR capacitance can sometimes lead to destructive LC voltage spikes when exposed to voltage transients.

This is only a simple model and does not include dielectric absorption (soakage) and other non-ideal effects associated with real electrolytic capacitors.

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.
