1, ESR Equivalent series resistance: Electrolytic capacitors are often used in circuits where current levels are relatively high. Also under some circumstances and current sourced from them needs to have a low source impedance, for example when the capacitor is being used in a power supply circuit as a reservoir capacitor. Under these conditions it is necessary to consult the manufacturers datasheets to discover whether the electrolytic capacitor chosen will meet the requirements for the circuit. If the ESR is high, then it will not be able to deliver the required amount of current in the circuit, without a voltage drop resulting from the ESR which will be seen as a source resistance.

2, Frequency response: One of the problems with electrolytic capacitors is that they have a limited frequency response. It is found that their ESR rises with frequency and this generally limits their use to frequencies below about 100 kHz. This is particularly true for large capacitors, and even the smaller electrolytic capacitors should not be relied upon at high frequencies. To gain exact details it is necessary to consult the manufacturers data for a given part.

Kingtronics Aluminum electrolytic capacitors are used in virtually every segment of the electronics industry, such as VTRs, videos, cameras, car radios and micro cassette tape recorders, etc.The longer lead is positive electrode and the shorter one is negative electrode.

General purpose and can be used in Industrial. Aluminum electrolytic capacitors are widely used to provide temporary voltage hold-up (they act as short-term energy sources) during transition periods (high load, line droops, and transient events).

Aluminum electrolytic capacitors are widely used to provide temporary voltage hold-up (they act as short-term energy sources) during transition periods (high load, line droops, transient events) within most electrical circuits.

Aluminum Electrolytic Capacitor, simply called Eelectrolytic Capacitor (e-cap), is a type of capacitor that uses electrolyte to achieve larger capacitance than other capacitor types. It consists of cathode aluminum foil, electrolytic paper, electrolyte, and aluminum oxide film, which acts as the dielectric, formed on the anode foil surface.

Due to its large capacitance, Aluminum Electrolytic Capacitor is suitable for passing or bypassing low frequency signals and storing large amounts of energy. It widely be used in power supplies and for decoupling unwanted AC components from DC power connections.

Kingtronics produce Aluminum Electrolytic Capacitor for many years. We sold this product in China and Hong Kong before. Because of good price and quality, we have much success in this item. Now we start offering this product to our oversea customers.

Surge arresters are classical components for protecting the installations of the telecommunications. It is essential that IT and telecommunications systems -with their high-grade but sensitive electronic circuits – be protected by arresters. They are thus fitted at the input of the power supply system together with varistors and at the connection points to telecommunication lines. They have become equally indispensable for protecting base stations in mobile telephone systems as well as extensive cable television (CATV) networks with their repeaters and distribution systems.

These protective components are also indispensable in other sectors:
● In AC power transmission systems, they are often used with current-limiting varistors
● In customer premises equipment such as DSL modems,WLAN routers, TV sets and cable modems
● In air-conditioning equipment
The integral black-box concept offers graduated protection by combining arresters with varistors, PTC thermistors, diodes and inductors to create an ideal solution for many applications.

What's cooperation? It is a process of groups working or acting together for common or mutual benefit. Based on the accumulated reputation and experience in the market, we have much confidence to increase your margin, especially on below diodes, it even helps you expand some business.

Most of us prefer cultivate relationships before do business together, please never hesitate to call or email us for any component demands, various cooperation methods can be supported.
