Electric Double Layer Capacitors (EDLC), Supercapacitors

The SCCR20B335SRB is a two-terminal electric double layer capacitor (EDLC) device, with a rated capacitance of 20F at 33 Volts. It is a supercapacitor or sometimes called an ultracapacitor, which has a significantly higher capacitance range than an electric fixed-value capacitor. This type of component is used for providing short-term energy storage and quick charge/discharge time applications.

Overview of the SCCR20B335SRB

The SCCR20B335SRB is part of Panasonic’s Standard model product line of EDLCs. With a maximum voltage of 33V, it is perfect for battery-free mobile and computer products. Other specifications include: capacitance of 20F, rated leakage current of 100nA, an effective internal resistance of 8 milliohms, and a rated operating temperature of -25oC to +85oC.

How does an EDLC work?

An EDLC consists of two electrodes that are separated by a separator material and an electrolyte. As an applied voltage is supplied to the device, ions from the electrolyte move towards the opposite electrode, creating an electric double layer at the electrode and electrolyte interface. This layer acts like a capacitor with a large surface area, resulting in a high capacitance value. When the device is discharged, the ions move back to the original electrodes. The ability to quickly store and release energy is one of the main advantages of EDLCs.

Applications of the SCCR20B335SRB

The SCCR20B335SRB EDLC can be used in a variety of applications. Thanks to its high energy density and short charge and discharge times, it is ideally suited for automotive and medical applications, including starter/stop systems, electric power steering, airbags, and back-up power systems. EDLCs can also be used to replace batteries in consumer and industrial products, providing better performance and longer service life. Additionally, EDLCs can be used as a power source for consumer electronics such as mobile phones, PDAs, and digital cameras. Its ability to provide bursts of high current make it ideal as an energy storage device for solar and wind energy applications.

Conclusion

The SCCR20B335SRB is a high-performance EDLC device with a high capacitance value, and is suitable for a wide range of automotive, medical, and consumer applications. With its wide temperature range and low internal resistance, it can provide quick charge/discharge times while delivering bursts of high current. As such, this device is a great choice for applications that require energy storage and quick charge/discharge times.
