Supercapacitors
Supercapacitors
Supercapacitors, also known as EDLC for Electric Double Layer Capacitor, are energy storage devices that are easy to use and, in many ways, comparable to batteries. They close the gap between capacitors and batteries.Supercapacitors have:
- Higher power density than batteries
- Higher energy density than conventional capacitors
Available series

The supercapacitor – A vertile energy storage device and how to use it
In the course of the presentation, important properties of Supercapacitors and key features of the design-in process will be discussed. Supercapacitors require, like any other energy storage system, a certain infrastructure in order to store and deliver their energy.

Redexpert
With the help of REDEXPERT you will find the right capacitor based on your technical requirements. The tool supports, for example, with measured values for capacitance, impedance, ESR and dissipation factor (DF). The ability to compare individual components with each other in terms of measured values enables convenient component selection.

Introduction to the capacitor technologies and how to use them
Capacitors make up two thirds of all electronic components and there is a huge diversity of technologies which can overwhelm young engineers. All capacitors store electrical energy in the electrical field created in a dielectric material and they are used for very diverse applications like voltage stability and filtering. How that works differs between tiny MLCCs and huge electrolytic cells, from pF ratings up to the hundreds of Farads in supercapacitors. In this presentation, we introduce different capacitor solutions taking into account the advantages and disadvantages and with a focus on the final application.
Design-in of capacitor module
The voltage of an electric double-layer capacitor (EDLC) depends on its charging state. Thus, the voltage at the terminals increases or decreases as soon as the EDLC becomes charged or discharged. To provide a stable voltage, the EDLC is often operated with a DC/DC conversion. Depending on the required power and charging voltage , it is required to design a module (see more: Constant Power Discharge Modul Calculator)
The EDLC module must provide the power required by the application. The EDLC Module Calculator calculates the size of the stack (module) based on the application parameter. Based on a given
- power demand,
- discharge time, and
- lower discharge limit,
the calculator provides the number of series and parallel connected EDLCs (defined by rated capacitance Cr and rated Equivalent series resistance (ESR) RESR ) as well as plots and other electrical parameters, such as total module capacitance C and total ESR R.

FAQ supercapacitors
![Datasheet WCAP-CSRF]( "FAQ Capacitors Datasheet")
For most parts you can find the detailed information about packaging in the datasheet: If you cannot find them, please get in contact with Würth Elektronik. E.g. you can use the chat on the website.
Example: Page 3 of WCAP-CSRF component datasheet.
You can find the certifications in the datasheet, page 2.
In the case of X/Y safety capacitors, certification information can be found in PDF format in the online platform REDEXPERT.
These links are shown at the right end of the table, under the column “Certificates”.
We provide the document with all the values on our homepage.
You can also download the document by searching for “FIT” or “MTBF” in our download center.
This document reveals the FIT (Failures in time) and MTBF (Mean time between failures) values that can be calculated for each series based on the electrical stress (voltage applied in the case of capacitors) and the temperature applied according to calculation models of Telcordia SR-332 Issue 3.
Please refer to the table of contents at the beginning of the document to find the values for capacitors.
![Diagram of the service life of EDLCs]( "Cycle life for EDLCs")
The cycle life is tested under ambient conditions. The charge discharge current is 100mA/F. During that test the capacitance change (decrease) is smaller than 30%. The internal resistance shall less than double. The waveform is given in the graph below.
Based on the endurance data the general Arrhenius Law can be used:
Lx = estimated lifetime
L0 = specified lifetime
T0 = upper specified capacitor temperature
Tx = actual operating temperature of the capacitor cell
