Also referred to as a condenser, a capacitor is a passive electrical component widely used to store electricity as an electrical charge. 
There are many types of capacitors available on the market. You can find very small ones available as capacitor beads utilized in resonance circuits. 
Large power factor correction capacitors are also available from very small to huge capacitors and everything in between, you would find a wide range of capacitors. However, they all serve one function and that is to store electrical charge.
 
The simplest type of capacitor available consists of 2 parallel conductive plates. These plates are separated via dielectric, an insulating material. 
This insulating layer interrupts the flow of DC current via the capacitor. Instead of DC current, a voltage across the plates is present in the form of an electrical charge.
Conductive plates are available in various shapes such as circular, cylindrical and rectangular. The insulating layer is either in the form of waxed paper, Air, Plastic or even in certain type of liquid gel. 
 
Electrical charge can be of two types namely positive and negative. Positive charge is present in the form of protons and negative charge in the form of electrons. The positive charge collects on a plate as soon as a voltage is placed across a capacitor. This is followed by a corresponding negative charge accumulation on the other plate. For each particle of positive charge a mining at one plate, a charge from similar will depart from- ve plate. The plates charge neutral. This is a potential different obtained from charge existing between two plates. The amount of charge that was deposited on the plates and the amount of capacitance the capacitor posses.
Capacitance is defined as the electrical property of a capacitor. It is the measure of the ability of capacitors for storing an electrical charge on two plates. In case, a voltage of (V) volts is connected across 2 plates capacitors, a positive electrical charge (2) will be present on one plate in coulombs and a negative charge on the other.This indicates that the capacitor will possess a capacitance valve equivalent to the amount of charge divided by voltage running across. This will proved the capacitance equation of (C=QV).

A good capacitor will have high dielectric resistance as well as zero plate resistance. This results in the charge flowing across the plates remaining constant for an indefinite period of time as soon as the source voltage was removed.

In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals. Inside the battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal. A capacitor is much simpler than a battery, as it can't produce new electrons -- it only stores them.

In theory, the dielectric can be any non-conductive substance. However, for practical applications, specific materials are used that best suit the capacitor's function. Mica, ceramic, cellulose, porcelain, Mylar, Teflon and even air are some of the non-conductive materials used. The dielectric dictates what kind of capacitor it is and for what it is best suited. Depending on the size and type of dielectric, some capacitors are better for high frequency uses, while some are better for high voltage applications. Suntan supply a wide range of capacitors,that can meet most of customers.

• Suntan Plastic Film Capacitors --- Have a wide range ,such as HID lamp, ECU for engine control
• Suntan Ceramic capacitor --- Used for high frequency purposes like antennas, X-ray and MRI machines

• Suntan Gold Capacitors --- CMOS's, microcomputers, RAM's and the like used in VCR's, tuners, TV sets, telephone sets and other.

During the Chinese National Day, most of Chinese companies would be closed from Oct. 1 to Oct. 7. While for providing better support to customers, Suntan sales office will keep open except Oct. 5. If anything need our feedback or if any new requirement, just please contact us freely and check our competitive price as always!

AVX stopped the production line of box type film capacitor including 5mm pitch capacitor and X2 safety capacitor. While, for both series Suntan can offer equivalence as TS05 and TS08S series. If you need to find a replacement, that would be a best choice for you. Both of these series have competitive price, excellent quality and short lead time as well beyond your expectation!

Suntan professional sales always focus on providing best service to customers through continuous improvement on product quality, production cost and prompt feedback. Hope this time we still can settle some customers' problem of urgent requirement!

The electronic device design and assembly industry, specially for Capacitive Discharge Ignition System, proper switch mode power supply (SMPS), lighting systemsshare large in India, which require Millions film capacitors. As per a customer of Suntan, Vishay/ Epcos were ruling this market but due to price pressure more and more manufacturers are looking at other options. The key is dielectric should be maintained or bettered as compared to Standards of Vishay/ Epcos, so the right option is limit. While more and more manufacturers are coming to Suntan for looking for replacements and new crossings as Suntan can offer right performance of capacitors, therefore stable shipments to India were increased gradually.

Suntan's plastic Film Capacitors with the high withstand-current performance of the conventional capacitors for photo flashes are used now widely for general appliances, industrial equipment, digital equipment, automotive electrical components, and hybrid cars which are required to offer high reliability and long life. All products are environmental-conscious and comply with RoHS Directive. The temperatures can go up to 105'C at most.
The general suitable types are listed as below:

Plastic film capacitor lines

Mylar film capacitor (small size)------------------------TS01
MKT Metallized film capacitor(standard)-----------------------TS02
Metallized film capacitor(AC voltage)---------------------- TS02A

The invention of the capacitor varies somewhat depending on who you ask. There are records that indicate a German scientist named Ewald Georg von Kleist invented the capacitor in November 1745. Several months later Pieter van Musschenbroek, a Dutch professor at the University of Leyden came up with a very similar device in the form of the Leyden jar, which is typically credited as the first capacitor. Since Kleist didn't have detailed records and notes, nor the notoriety of his Dutch counterpart, he's often overlooked as a contributor to the capacitor's evolution. However, over the years, both have been given equal credit as it was established that their research was independent of each other and merely a scientific coincidence.

The Leyden jar was a very simple device. It consisted of a glass jar, half filled with water and lined inside and out with metal foil. The glass acted as the dielectric, although it was thought for a time that water was the key ingredient. There was usually a metal wire or chain driven through a cork in the top of the jar. The chain was then hooked to something that would deliver a charge, most likely a hand-cranked static generator. Once delivered, the jar would hold two equal but opposite charges in equilibrium until they were connected with a wire, producing a slight spark or shock.

Benjamin Franklin worked with the Leyden jar in his experiments with electricity and soon found that a flat piece of glass worked as well as the jar model, prompting him to develop the flat capacitor, or Franklin square. Years later, English chemist Michael Faraday would pioneer the first practical applications for the capacitor in trying to store unused electrons from his experiments. This led to the first usable capacitor, made from large oil barrels. Faraday's progress with capacitors is what eventually enabled us to deliver electric power over great distances. As a result of Faraday's achievements in the field of electricity, the unit of measurement for capacitors, or capacitance, became known as the farad.
