Electric Double Layer Capacitors (EDLC), Supercapacitors, have revolutionized the energy storage sector over the past couple of decades. They combine traditional electrostatic capacitors with a porous carbon electrode in order to achieve unprecedented power densities and unparalleled performance in a variety of applications. PAS2126FR2R5504, a product of Yageo’s Volteq series of supercapacitors, is a testament to the great potential of these devices. This article will discuss its relevant application fields and its underlying working principle.

Application Fields

The size and large energy capabilities of PAS2126FR2R5504 make it especially suited for applications that require high energy transfer over short periods of time, such as energy harvesting and starting motors with a peak current of over 7000A. It is also an optimal choice when a unit needs to apply large current bursts to drive mainly inductive loads. For example, some medical devices or automotive systems require a short surge of current for charging their power sources. This supercapacitor can definitely meet these demanding requirements.

Yet there are more traditional applications that take advantage of its capabilities, and one such example would be its usage as a volatile backup energy source on circuit boards. In case of a sudden power loss, it bridges the gap, providing a stable voltage output until the main source of power is restored. This prevents crucial data as well as other important information from being corrupted or inadvertently deleted.

Working Principle

The PAS2126FR2R5504 is composed of two carbon electrodes with a porous separator in between. The porous separator has a functional group that interacts with ions and creates an electrical double layer at the boundary. When electric charge is applied to one side of the device, the opposite side will accumulate charge due to the attraction generated by the double layer.

Furthermore, thanks to its unique structure, the PAS2126FR2R5504 provides the combination of a high energy density with a high power density as well. The high energy density is a result of the increased capacitance achieved by using a carbon separator, while the high power density is mainly due to the device’s low internal resistance.

This supercapacitor can be recharged by applying a constant Voltage in its terminals, which will lead to the electrons shifting from the negative to the positive electrode as current flows through the device. This phenomenon, known as Faradaic Charge/Discharge, is the main principle on which the capacitor operates.

In conclusion, the PAS2126FR2R5504 from Yageo’s Volteq series of supercapacitors is a highly capable device whose application fields range from medical equipment and automotive systems to circuit boards. It combines an impressive energy capacity with an incredibly low internal resistance, thus providing unparalleled power and performance. As the name implies, the main principle of its functioning relies on the concept of the electric double layer.
