Electric Double Layer Capacitors (EDLC), commonly known as Supercapacitors, are a class of energy storage devices that offer relatively high capacitance values compared to traditional capacitors. The CDLC401K2R7SR is a member of the EDLC family and is one of the most widely used Supercapacitors available in the market. This article will discuss the application field and working principle of the CDLC401K2R7SR.

Application Field

The CDLC401K2R7SR is a general-purpose Supercapacitor designed to supply short-term power to support low power electronics applications. It has an open circuit voltage rating of 2.7 volts, which is suitable for powering most small electronic circuits. Typical applications for the CDLC401K2R7SR include intermittent duty cycle devices such as: automatic door openers, electrochemical relays, emergency power systems, door locks, optoelectronic switch, solenoid valves, robots, medical implants, and more.

The CDLC401K2R7SR is well suited for applications where a small amount of energy is needed for a short period of time. This Supercapacitor has low equivalent series resistance (ESR) and high capacitance. The combination of low ESR and high capacitance makes it ideal for delivering bursts of energy to quickly power up microcontrollers or to provide the needed input to peripheral devices such as LCDs.

Working Principle

The CDLC401K2R7SR works based on the principles of an electric double layer capacitor (EDLC). This type of capacitor includes two electrodes that are separated by a highly resistant separator. By applying an electric potential between the two electrodes, a charge accumulates on the surfaces of both electrodes. This accumulation of charge produces an electric field along the length of the capacitor which stores energy.

The CDLC401K2R7SR has an insulated outer shell which acts as a dielectric material between the two electrodes. This insulation helps protect the Supercapacitor from environmental influences such as temperature and humidity while increasing the maximum capacitance of the device. The dielectric material also helps keep the voltage across the terminals of the Supercapacitor at a constant level.

The CDLC401K2R7SR is also equipped with a polypropylene-film-insulated terminal. This terminal provides a stable and reliable connection to the device to ensure a consistent energy delivery. The terminal also helps reduce the risk of short-circuiting or arcing.

In conclusion, the CDLC401K2R7SR is a versatile Supercapacitor that can be used for a wide range of power supply applications. It has a high capacitance, low ESR, and a polypropylene-film insulated terminal allowing it to efficiently supply short-term power to low power electronics equipment. Its application field includes intermittent duty cycle devices such as automatic door openers, electrochemical relays, emergency power systems, door locks, optoelectronic switch, solenoid valves, robots, medical implants, and more.
