Aluminum-polymer capacitors combine the benefits of traditional aluminum electrolytic capacitors in terms of stable electrical performance, robustness and reliability, with the higher capacitance density of polymer capacitors. The ESRD181M02B is an example of this new generation of capacitors. It is a large-capacity, high-voltage aluminum-polymer capacitor, suitable for a wide range of applications.

General Properties of Aluminum-Polymer Capacitors

Aluminum-polymer capacitors have greater capacitance density than aluminum electrolytic capacitors, with the same size and voltage rating. This allows designers to utilize smaller sized components, reducing board space and overall cost. In addition, they possess strong energy storage capability and can provide lower ESR (equivalent series resistance) than their aluminum electrolytic counterparts, especially at higher frequency ranges. This results in improved high-frequency noise filtering and power output. Finally, aluminum-polymer capacitors are environmentally friendly, as they contain no harmful electrolytic liquid, eliminating the risk of leakage, providing improved durability and extreme temperature performance.

Features and Benefits of the ESRD181M02B

The ESRD181M02B is a high-ended electric double-layer capacitor, combining the features of aluminum-polymer with a broad range of electric double-layer features. With its robust construction, this capacitor series stands up to normal environmental and mechanical stresses. Additionally, it features a low equivalent series resistance of 30 mΩ, low equivalent series inductance of 0.5 μH, as well as low internal losses, thereby providing outstanding high-frequency noise filtering and power output. The ESRD181M02B series also offers a wide range of temperature range, provided by the low equivalent series resistance (ESR) of 30 mΩ, low equivalent series inductance of 0.5μH, and low internal losses.

The ESRD181M02B series capacitors can also be used in LED lighting applications, solar cell modules, and electric vehicles such as hybrid vehicles, electric scooters, and other transportation equipment.

Working Principle of ESRD181M02B

The ESRD181M02B works on the principle of electrostatic double-layer capacitors which are composed of two electrodes having opposite electrical properties. One of the electrodes is a carbon-based layer called the activated carbon material, and the other is a dielectric layer called non-activated carbon material. When a voltage is applied across the electrodes, electric double-layer capacitance is produced. The size of this electric double-layer capacitance is determined by the area and nature of the activated carbon layer and the size of the non-activated carbon material layer. This electric double-layer capacitance is known as ESRD181M02B electric double-layer capacitance.

In the ESRD181M02B electric double-layer capacitance, each electrode has its own capacitance value. The capacitance of the activated carbon layer is much larger than the capacitance of the non-activated carbon material layer. As a result, the electric double-layer capacitance of the ESRD181M02B is increased, resulting in a larger capacitance value. The capacitance value of the ESRD181M02B electric double-layer capacitance is also increased by using a larger area and a lower number of electrodes.
