Aluminum Electrolytic Capacitors

An Aluminum Electrolytic Capacitor, also known as an Alumiconn, is a type of capacitor that utilizes an aluminum and an electrolyte solution as its working parts. It uses an oxide film on the surface of the aluminum to form the electric field. It is a type of "polarized" capacitor, meaning it must be placed in a certain direction in order to function correctly. The aluminum electrolytic capacitor plays an integral part in modern electronics, as it is used in a variety of applications, including power supply circuit chip filters, stereo audio systems, microwave ovens, and air conditioning systems.

TVA1318.5 Application Field and Working Principle

The TVA1318.5 aluminum electrolytic capacitor is a high voltage, high temperature, long life capacitor designed for use in a wide variety of high frequency, low cost applications. It consists of a thin aluminum anode with a thick aluminum oxide coating and a porous polyester sleeve. The anode and sleeve, along with the electrolyte solution, form the structure of the capacitor. The electrolyte solution works to reduce the interfacial resistance between the anode and the oxide layer, allowing it to store and release electrical energy.

The TVA1318.5 is especially well-suited for applications such as voltage stabilization circuits, post and pre-reg DC power sources, communication equipment, and power supply circuits. It has a DC voltage rating of 500V and is especially well-suited for high-frequency applications with its low series inductance and high insulation resistance. The high surge capability of this capacitor also makes it a viable option for pulse, dynamic voltage, and high frequency circuits. Other features include a long working life of up to 4000 hours, and high temperature operation of up to 130°C.

The working principle of an aluminum electrolytic capacitors is that, when a voltage is applied across the two electrodes, ions in the electrolyte become attracted to the anode and form an extremely thin dielectric layer on the anode\'s surface. This layer, also known as the oxide layer, greatly increases the capacitance of the capacitor. This oxide layer is formed by electrons evicting ions from the surface of the anode and forming a film of oxide around it. The formation of the oxide layer allows the capacitor to store electrical energy in the form of a static charge.

The capacitance of the TVA1318.5 can be adjusted by changing the amount of electrolyte solution and the temperature of the operating environment. The capacitance of the TVA1318.5 is particularly stable over a wide temperature range given the presence of an optimized electrolyte solution. This stability makes the TVA1318.5 particularly desirable for applications where dynamic capacitance changes may occur.

The TVA1318.5 aluminum electrolytic capacitor is an excellent choice for a wide range of power supply circuit chip filtering, audio, and microwave oven applications. Its high surge capabilities and long working life make it an ideal choice for voltage stabilization and post/pre-reg DC power sources. The high temperature and voltage ratings of this capacitor gives it additional versatility when deployed in extreme environments. The TVA1318.5 aluminum electrolytic capacitor is a reliable and cost-effective option that can be counted on to operate reliably and efficiently.
