Aluminum-Polymer capacitors are capacitors consisting of many layers of aluminum foil with a thin layer of polyethylene terephthalate (PET) electrostatically adhered to each layer. Aluminum-Polymer capacitors are very similar to electrolytic capacitors, however, they offer much better performance in a wide temperature range and enable higher power densities. The 2SWZ330MDELX series of aluminum-polymer capacitors is a good example of this type of device.

The 2SWZ330MDELX application field is mainly used in smaller, lighter power electronic design, especially for audio and high frequency energy storage applications. Its high energy density per unit volume makes it suitable for low profile and low profile applications. The 2SWZ330MDELX can also be used in capacitive power converters and supply circuits, such as dc-dc Converters, switch-mode power supplies and industrial control power supplies.

The working principle of the 2SWZ330MDELX is quite simple. It consists of two electrodes, an anode and a cathode, which are punched out of two aluminum foils. A thin layer of polyethylene terephthalate (PET) is electrostatically adhered to the aluminum foils forming the dielectric layer. The PET layer acts as an insulator between the two electrodes. This PET layer is then chemically modified and treated to improve its robustness and long life. Finally, a metallized outer surface and an inner contact layer are created to provide better electrical performance, robust connection to the electrical circuit and improved environmental conditions.

In terms of performance, the 2SWZ330MDELX offers high capacitance density, low equivalent series resistance (ESR) and low losses over the entire temperature operating range. It has low temperature coefficient and offers excellent high frequency response. These properties make it suitable for applications requiring high power density and high performance including DC/DC conversion, switch mode power supplies and industrial control power supplies.

The 2SWZ330MDELX also features a wide range of capacitance values ranging from 1.5uF to 47uF. These values enable it to be used for a variety of applications including power factor correction (PFC) power supplies, UPS applications, audio and energy storage or even supercapacitors. It is also widely used in protection and filter applications such as surge suppression, voltage transient absorption and filtering of high frequency noise.

In addition, the 2SWZ330MDELX offers excellent reliability and long life. It is designed with a low temperature coefficient and robust construction that is able to withstand the harsh operating conditions of industrial applications. This makes it suitable for applications that are subject to frequent thermal changes or under harsh environments.

In summary, the 2SWZ330MDELX series of aluminum-polymer capacitors is a reliable and high performance device. It features a broad range of capacitance values enabling its use in a variety of power converters, power supplies and filter applications. Its ability to withstand high voltage transients make it suitable for use in industrial control and power electronics applications. Its high energy density, low ESR and low losses combine to make it the perfect choice for smaller, lighter power electronic designs including audio and high frequency energy storage applications.
