Electric Double Layer Capacitors (EDLC)

Electric double layer capacitors (EDLC) are also known as ``supercapacitors" or ``(ultra) capacitors." They are electrochemical capacitors that are characterized by their exceptionally high capacitance values and rapidly changing capacitance. These capacitors are used to store energy in the form of static charges between two close proximity electrodes. They have higher volumetric capacity than regular capacitors, possess exceptionally low internal losses, and always remain inversely polarized.The HV1860-2R7107-R is an example of an electric double layer capacitor. It is a non-aqueous, high-voltage supercapacitor with a capacitance of 2.7 Farads. It has a large and flat energy compression curve that is ideal for applications requiring long hold times. It also has an operating voltage of 1.8V to 2.7V, making it suitable for various types of dc-dc converters and boost converters.

Working Principle of EDLCs

Electric double layer capacitors (EDLCs) work by storing static charges between two closely spaced electrodes. The charge storage relies on electrostatic double-layer capacitance between the electrodes, which is much higher than the conventional capacitance of regular capacitors. The stored charge is then released through anelectrochemical reaction between the electrodes and the electrolyte. The charge cycle in an EDLC is initiated by applying a voltage across the electrodes. This creates an electrostatic double layer with stored positive and negative charges on the surface of each electrode. When coupled with a compatible electrolyte, the charges interact and store the static charges. Upon application of a discharge signal, the charges are released through the electrochemical reaction.

Applications of HV1860-2R7107-R

The HV1860-2R7107-R has a large range of applications that take advantage of its high volumetric capacity, flat energy compression curve, and long hold time capabilities. Some of the most common applications include:

• Power supply: This capacitor is often used in DC-DC converters and boost converters, providing frequent storage of energy for peak loads. It is also used in switching regulation, which uses microprocessors and other digital circuits.
• Energy harvesting and renewable energy sources: EDLCs, such as the HV1860-2R7107-R, are ideal for capturing and storing energy from renewable sources such as solar and wind power. This allows for longer periods of operation and a more reliable supply of energy when used in combination with an energy harvesting system.
• Automotive: EDLCs are used in a variety of automotive applications, ranging from regenerative braking to power steering. They are also used in hybrid vehicles as a way to store energy for short bursts of power.
• Consumer electronics: EDLCs are a popular choice in any application requiring low leakage current, such as portable digital products, wireless headsets, Bluetooth devices, and other consumer electronics.
• Power backup: EDLCs can be used to provide power backup for sensitive circuits and systems in case of an unexpected outage.

In conclusion, the HV1860-2R7107-R is a versatile and reliable supercapacitor that can be used in a variety of applications, thanks to its flat energy compression curve, long hold times, and excellent volumetric capacity. It is an ideal choice for application where frequent storage of energy is required, as well as for operations that rely on energy harvesting and renewable energy sources.
