Introduction

Aluminum – polymer capacitors are composed of a dielectric layer, with a sandwiched aluminum foil and polymer electrolyte. This unique combination of components, offers electrical performance advantages over traditional ceramic or aluminum electrolytic capacitors. These components offer greater stationarity and vibration resistance. Additionally, they have a longer lifespan than traditional methods are able to provide.The 870056175003 Aluminum - Polymer Capacitor is one such product, which has been designed to provide higher capacitance in a more compact size than available with conventional aluminum electrolytic capacitors.

Application Field

The 870056175003 Aluminum – Polymer Capacitor is primarily used in industrial and home appliances, such as air conditioners, refrigerators, washers and dryers, and microwave ovens. Due to their high capacitance values and high current capability, the capacitor is also employed in the automotive and medical industries, and in the power supplies of various electronic equipment. Its performance characteristics are further utilized in the communications and aerospace sectors, for use in high power supplies.Furthermore, the 870056175003 Aluminum – Polymer Capacitor is also effective for use with computers, as part of a voltage regulation system. Used most commonly in this capacity, the high power supply efficiency, low ESR, high throughput and extended lifecycle are essential components of the modern computer\'s design.

Design Features

The capacitors of the 870056175003 Aluminum - Polymer Capacitor have a range of design features, including a wide-range of operating temperature range -40 °C to + 125 °C, a high voltage rating of 2V-12V and a wide capacitance range of 2.2uF to 470uF.Additional features, such as an operating temperature range of -50 °C to + 125 °C, a ripple current up to 4A, an enhanced thermal dissipation and a low ESR of 10mΩ are also available. The design of the 870056175003 Aluminum – Polymer Capacitor is also designed to ensure that the corrosion resistance is maintained, ensuring a longer lifespan.

Working Principle

The 870056175003 Aluminum – Polymer Capacitor works by storing electrical charge on a thin film and is then released when required. This thin film is achieved by the use of two pieces of aluminum foil, separated by a dielectric layer, with a electrolyte solution in between.When no electrical current is applied to the capacitor, the electrical charge is not released. However, when an electrical current is applied, the electrolyte solution breaks down and allows current to pass through the capacitor. The electrolyte solution then reforms when the current is removed, and the capacitor is recharged for future use.The 870056175003 Aluminum – Polymer Capacitor also utilizes a unique technology to ensure that the capacitance remains constant over a wide temperature range. This technology ensures that the usage lifespan of the capacitor is greatly increased, and that the performance remains at a much higher level for longer.

Conclusion

The 870056175003 Aluminum – Polymer Capacitor is an innovative and highly versatile component, which is well suited to both industrial and home applications. Its ability to deliver a higher capacitance in a smaller size than conventional aluminum electrolytic capacitors offers many engineering and technical benefits, as it is well suited to a wide range of applications. Additionally, its design features account for a wide range of operating temperatures, voltages and capacitance values, enabling the component to effectively meet the needs of the most demanding applications.
