---All Kinds of Capacitors

Since 1978, Suntan Technology Company Limited started in selling all kinds of capacitors from our headquarters in Hong Kong. We mainly produce Dipped & SMD Tantalum Capacitors, Radial & SMD Multilayer Ceramic Capacitors and Aluminum Electrolytic Capacitors.

Here, we focus on introducing the aluminum electrolytic capacitor. It has radial type, axial type, SMD type, snap in type, screw type and LUG type. TS14, as the example of aluminum electrolytic capacitor, belongs to the radial type. Its characteristical includes wide temperature range, long life, mininature and low impedance.

Below is some information about it for you referance.

Suntan introduces the TS13DE - CD11OX series of radial leaded aluminum electrolytic capacitors.  What's radial capacitors ? Radial capacitors have two leads which stick out from the bottom of the capacitor. They are a different configuration to axial capacitors in that sense because axial have one lead that sticks out from either end.

By improving material technology, Suntan has been able to increase lifetime to 2,000 hours at 85°C—over previous generation products and also improve capacitance tolerance. These capacitors are suitable for switching mode adapters, line noise removal and other products with long lifetime requirements

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, but with performance disadvantages. All capacitors conduct alternating current (AC) and block direct current (DC) and can be used, amongst other applications, to couple circuit blocks allowing AC signals to be transferred while blocking DC power, to store energy, and to filter signals according to their frequency. Although most electrolytic capacitors are polarized; hence, they can only be operated with direct current (DC). The large capacitance of electrolytic capacitors makes them particularly suitable for passing or bypassing low-frequency signals and storing large amounts of energy. They are widely used in power supplies and for decoupling unwanted AC components from DC power connections.
 
Electronic capacitors are one of the most widely used electronic components. These electronic capacitors only allow alternating or changing signals to pass through them, and as a result they find applications in many different areas of electronic circuit design. Suntan supply a wide variety of types of capacitor including electrolytic, ceramic, tantalum, plastic, sliver mica, and many more. Each capacitor type is introduced in www.suntan.com.hk.
 
Two types of electrolytic capacitor are in common use: aluminum and tantalum. Tantalum capacitors have generally better performance, higher price, and are available only in a more restricted range of parameters. Solid polymer dielectric aluminum electrolytic capacitors have better characteristics than wet-electrolyte types—in particular lower and more stable ESR and longer life—at higher prices and more restricted values.

One of the main application classes of aluminum electrolytic capacitors is input capacitors for power inverters.
The aluminum electrolytic capacitor provides a unique value in high energy storage and low device impedance. How you go about selecting the right capacitor or capacitors, however, is not a trivial matter.

Selecting the right capacitor for an application requires a knowledge of all aspects of the application environment, from mechanical to thermal to electrical. The goal of this paper is to assist you with selecting the right capacitor for the design at hand.

Capacitor ripple current waveform considerations. Inverters generally use an input capacitor between a ectified line input stage and a switched or resonant converter stage.

Suntan aluminum Electrolytic capacitors store charge in a chemical paste called an electrolyte. They have large capacitance values, and are inexpensive and durable. Electronic designers typically use electrolytic capacitors to remove electrical noise from circuits. Since these capacitors are polarized, you must pay attention to the positive and negative leads or risk an explosion. When you use electrolytic aluminum capacitor, note that it has its capacitance and voltage values clearly printed on the body of the part. 

Electrolytic capacitors have capacitance ratings in the range of 10 to 200,000 microfarads. The voltage rating is the maximum voltage to which the capacitor should be subject. Maximum voltages for electrolytic generally range from 20 to 600 volts.

Suntan manufacture a wide range of Aluminum Electrolytic Capacitors, Including Snap-in type Electrolytic Capacitor, Screw type and LUG type Aluminum Electrolytic Capacitor, Axial & Radial Electrolytic Capacitor and SMD Aluminum Electrolytic Capacitor etc.

Aluminum electrolytic capacitors are comprised of anode and cathode plates separated by an absorbent spacer. As shown in Figure below, metal tabs are attached to the anode and cathode plates, and the assembly is wound into a cylindrical section. The tabs are welded to aluminum terminals installed in a header (top). The section-header assembly is immersed in a bath of hot capacitor electrolyte (significantly different from the formation process electrolyte). In what is called the impregnation process, a vacuum is applied to the electrolyte and sections, causing electrolyte to be drawn into the sections, thoroughly wetting the sections. The sections are placed in aluminum cans, and the headers are sealed to the cans. The capacitor units are slowly brought up to maximum rated voltage at maximum rated temperature during the aging process. The aging process grows oxide on areas on the anode foil which have an insufficient oxide barrier, such as slit edges and places which have been cracked during the winding operation. Inspections and tests occur at several stages of the production process.

When an aluminum electrolytic capacitor is stored under no load conditions for a long period of time, its leakage current tends to increase slightly. This is due to a drop in the withstand voltage of the dielectric caused by the reaction of the anode oxide layer with the electrolyte. When the voltage is applied to the capacitor, the leakage current returns to its initial level because of the re-forming action of the electrolyte (called voltage treatment). If the storage temperature is high, the leakage current will increase substantially. Therefore, it is desirable to store capacitors at normal temperature level with no direct sunlight. A voltage treatment is recommended when using a capacitor stored for a long period of time. The treatment for an individual capacitor is accomplished by charging up to its rated voltage through a resistance of about 1 kΩ and applying the voltage for approximately 30 minutes.
