Aluminum - Polymer Capacitors, or SPSX271M0ER-7, are types of capacitors which are composed of three layers: aluminum layers and a double layer, or bi-layer, film dielectric. The aluminum layers are generally separated by a distance of several microns, allowing an electric charge to build up between them. These capacitors are characterized by their large capacitance, low ESR, narrow tolerances, and very temperature independent characteristics, making them ideal for use in a wide variety of applications.

Application Field

Aluminum - Polymer Capacitors have many uses. Due to their large capacitance and low ESR, they are often used in power supplies, regulators, switching circuits, and automotive electronics. They can also be used in noise filtering applications and as dampeners, where their high capacitance can act as a shock absorber, preventing sudden changes that can affect system operations and equipment performance.

In addition, Aluminum - Polymer Capacitors have applications in storage. Used in combination with supercapacitors, these capacitors can store enough energy to power large data centers and other power-demanding applications. Programs like the NASA Space Station and large telecom data centers rely on these capacitors for electrical power.

The SPSX271M0ER-7 model of Aluminum - Polymer Capacitors is widely used in commercial and industrial liquid-cooling systems. Utilizing the thermoelectric effect, these capacitors work in conjunction with fins and heat sinking mechanisms to absorb and dissipate heat from the system.

Working Principle

Aluminum - Polymer Capacitors work on an electrostatic principle. Two electrical plates of different polarity are separated by an electrolyte, or dielectric. An electric current is then passed through the capacitor, thus creating an electric field that stores an electrical potential.

The SPSX271M0ER-7 model of Aluminum - Polymer Capacitor has a unique construction which ensures greater capacitance and stability. This model has an optimized anode layer, made of an aluminum sheet which consists of a honeycomb-like structure that is filled with numerous interconnected meta-laminated aluminum particles. This provides greater capacitance by allowing a considerable amount of charge to be stored on the electrodes.

The double layer film dielectric used in this model is made of a polypropylene film, with a polyethylene inner layer. This design eliminates flaws associated with single layer films, providing greater efficiency, and allowing for a longer life cycle.

The design also employs an optimized construction that increases the cycling behavior of the capacitor. This cycling behavior, or the ability of the capacitor to last over multiple cycles of charge and discharge, is a factor when selecting capacitors for applications in the automotive or aerospace industries.

These capacitors offer low ESR ratings, which means they can provide large current without significant reductions in output voltage. This makes them ideal for use in DC-DC converters and power supplies, as they can provide stable power without fluctuations over long periods of time.

The SPSX271M0ER-7 offers a temperature independent characteristic, making it suitable for operating in extreme temperatures. This is important in devices or locations that experience frequent temperature changes, such as the interior and exterior of a car.

Aluminum - Polymer Capacitors are a versatile and reliable source of energy and stability for a variety of applications. With their low ESR, large capacitance, and temperature independent characteristics, these capacitors are a great choice for power supplies, regulators, and noise filtering applications.
