TDK's EDLC/Supercapacitors have high capacitance and low profile.
TDK's pouch-type EDLC/Supercapacitors feature a low-resistance and low-profile design that makes full use of the high capacitance.
They can provide instantaneous peak power assistance, backup power when the power supply is interrupted, output stabilization, and other effects. They also contribute to limiting the height of the mounting area.
TDK's EDLC/Supercapacitors expand the possibilities of application development.
Three Key Features that Expand the Possibilities of Application Development
-
Battery Assist
By assisting battery output limits, it is possible to achieve functions that would have to be abandoned if operating by battery alone.
EDLC/Supercapacitors can assist for example electronic paper, and power supply to smart meters with advanced functionality.
They contribute to extending lifespan and miniaturization of batteries, and the low-profile enables space saving. -
-
Power Backup
The massive amount of energy stored in EDLC/Supercapacitors can be used as a backup in the event of power loss.
They help to achieve stable operation of devices by providing backup power to protect SSD data, and contribute also to space-saving. -

Efficient Energy Use and
Power StabilizationEDLC/Supercapacitors can effectively use energy by storing micro-energy or regenerative energy.
They supply applications with stored energy when it is necessary.
In addition, they are excellent in storing micro-energy generated in variety of applications, making them ideal as storage devices for energy harvesting. -
Application Examples
-
Smart Meters
Contribution to space-saving, longer lifespan and miniaturization of batteries.
Water and gas smart meters are having increasingly advanced functions as wel as wireless transmission of information. EDLC/Supercapacitors enhance the wireless functions of battery operated water and gas smart meters, and are effective for battery assist when power assistance is needed.
-
Electronic Paper
Enable smooth screen refresh rate.
Electronic paper requires improved screen rewriting speeds and more comfortable operation. Smooth electronic paper screen rewriting requires a large current, and EDLC/Supercapacitors are effective for providing battery assistance. This contributes to miniaturization of the battery required.
-
SSDs
A single EDLC/Supercapacitors can provide the same amount of energy, or more, as multiple electrolytic capacitors.
In enterprice SSDs data transfer from cache to NAND flash memory is required in case of power failure. This is still generally supported by Tantalun capacitors and other power loss protection measures. Space saving is possible by replacing those capacitors with high-capacitance EDLC/Supercapacitors.
