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.

Suntan always focuses on synchronously refreshing the technical specification between our website and the paper brochure/ sample box, which makes customer know more detailed information about our components and Suntan brand.

This time we updated the brochure of Rectifier Diode M7 and Trimming Potentiometer first, M7 brochure photo as below. Plastic Film Capacitor is under construction, and other series will show up soon!

Meanwhile, as for the sample box, we put some more typical samples into the box such as radial and axial film capacitor, X2 capacitor, radial and SMD E-caps. We hope this would give customer a more complete idea of our full products.

Welcome all old or new customers ask for our New Brochure and Sample Box!

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.

Large capacitors are connected to the amplifier much the same way a battery is. This means that the capacitor's positive terminal is connected to the amplifier's positive terminal (which also means that it's connected to the battery's positive terminal). The same is true of the capacitor's negative terminal (the cap's negative terminal is connected to chassis ground with the amplifier's negative ground terminal). Like this...

Large capacitors are used as a sort of electrical shock absorber. As voltage starts to rise, the capacitor will absorb energy which will tend to keep the voltage from rising as quickly as it otherwise would. If the voltage starts to fall, the capacitor's stored energy will flow out of the capacitor to try to keep the voltage up. A capacitor's ability to absorb/release energy from/to external circuits depends on the capacitor's specs (capacitance, ESR, ESL...), the output impedance of the power source (alternator and power wire in this case) and the circuit's input impedance (into the amplifier's power supply).

Suntan is a tinfoil capacitor of the highest class. Solid tinfoil, together with high grade polypropylene as dielectric, are used in its manufacture. This massive tin layer improves the sound properties in unexpected ways: Because of the great weight of the tinfoil and the resulting mass inertia, oscillation of the foil and the accompanying micro phonic effect are effectively prevented.

No matter where you use the Suntan Supreme--as a coupling capacitor in your CD player or amplifier, or in the crossover of your speakers--you always get the same surprising and impressive performance. This capacitor mobilizes such unbelievable reserves in your sound system that it is really justified to speak of a new dimension of music reproduction. Furthermore, the effect is not only achieved with very expensive high-end components. It delivers a significant enhancement in more price-conscious configurations, making it a very worthwhile upgrade.

A capacitor (formerly known as condenser) is a passive electronic component consisting of a pair of conductors separated by a dielectric (insulator). When there is a potential difference (voltage) across the conductors a static electric field develops in the dielectric that stores energy and produces a mechanical force between the conductors. An ideal capacitor is characterized by a single constant value, capacitance,measured in farads. This is the ratio of the electric charge on each conductor to the potential difference between them.

Capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass, in filter networks, for smoothing the output of power supplies, in the resonant circuits that tune radios to particular frequencies and for many other purposes.

Most types of capacitor include a dielectric spacer, which increases their capacitance. These dielectrics are most often insulators. However, low capacitance devices are available with a vacuum between their plates, which allows extremely high voltage operation and low losses. Variable capacitors with their plates open to the atmosphere were commonly used in radio tuning circuits. Later designs use polymer foil dielectric between the moving and stationary plates, with no significant air space between them.

In order to maximise the charge that a capacitor can hold, the dielectric material needs to have as high a permittivity as possible, while also having as high a breakdown voltage as possible.

The capacitor (C) in the circuit diagram is being charged from a supply voltage (Vs) with the current passing through a resistor (R). The voltage across the capacitor (Vc) is initially zero but it increases as the capacitor charges. The capacitor is fully charged when Vc = Vs. The charging current (I) is determined by the voltage across the resistor (Vs - Vc):

Charging current, I = (Vs - Vc) / R   (note that Vc is increasing)

At first Vc = 0V so the initial current, Io = Vs / R

Vc increases as soon as charge (Q) starts to build up (Vc = Q/C), this reduces the voltage across the resistor and therefore reduces the charging current. This means that the rate of charging becomes progressively slower.
