Construction

Drawing of a wound capacitor with labels for anode foil, cathode foil, separator paper (soaked with electrolyte), and terminals for anode and cathode.

Wound capacitor

Aluminum electrolytic capacitors are wound capacitors. These consist of aluminum foils with a layer of paper in between.

Cross-sectional diagram of an aluminum electrolytic capacitor with labels for anode (aluminum foil), cathode (aluminum foil), separator paper (soaked with liquid electrolyte), dielectric (oxide layer), and liquid electrolyte. Positive (+) and negative (-) terminals are indicated at the top of the diagram.

Layer structure

The aluminum foil of the anode is formed by anodic oxidation before winding, so that the dielectric (oxide layer) is strengthened. The wound capacitor is completely soaked in electrolyte. This electrolyte is evenly distributed through the paper layer. In addition, the paper layer ensures a distance between the anode and cathode foil.

Measurements

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.

Lifetime

Lifetime calculator

With this tool you can calculate your maximum expected lifetime. Depending on the product family, a different formula is used for the calculation. This calculator can be found in the aluminum capacitor module on the REDEXPERT platform.

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.

Application notes and documents

  • All Capacitors are "Audio Capacitors"

    There is an ongoing discussion within the audio engineering community about the sound quality of amplifiers concerning the audibility of signal distortions. Apparently, capacitors used for coupling and decoupling signals are suspected to be the source or at least a contributor to high-frequency distortions that influence the hearing impression.

  • Application Note ANP071: Aluminum Electrolytic vs. Aluminum Polymer Capacitor and how its benefits are used properly

    Aluminum polymer capacitor is a sub-form of the electrolytic capacitors. The special feature of these capacitor types is that a conductive polymer is used instead of a liquid electrolyte. This requires a special processing step, which is carried out during production. In this chemical reaction, the so-called polymerization, by heating, the still liquid monomer that has been impregnated in place of electrolyte in the separator paper is cross-linked to a solid polymer.

  • Support Note SN008: Expected Lifetime of Aluminum Electrolytic and Aluminum Polymer Capacitor

    The life cycle of a capacitor depends on many factors of the application. An important factor is the temperature or rather thermal load, as it is responsible for the fact that internal structures age over time and the electrical properties deteriorate. This results in increased leakage current, increasing the ESR, which in turn leads to a further increase of the temperature.

    The life cycle of a capacitor depends on many factors of the application. An important factor is the temperature or rather thermal load, as it is responsible for the fact that internal structures age over time and the electrical properties deteriorate. This results in increased leakage current, increasing the ESR, which in turn leads to a further increase of the temperature.

  • Support Note SN019: Afraid of aging? The effects of time on electrolytic capacitors

    Since the development and production of electrolytic capacitors, designers have had to deal with the issues of aging and shelf life of these products. Electrolytic capacitors have been around for a very long time, but the rapid increase did not occur until the 1960s. There are still many "myths" from that time that revolve around the aging and shelf life of these capacitors.

  • ANP125 Acoustic Effect of Harmonic Distortions caused by Aluminum Electrolytic Capacitors

    This note reports a comparative study of total harmonic distortions (THD) caused by commercial electrolytic capacitors, as produced by Würth Elektronik eiSos as well as purpose-built items. The discussion about the audibility of distortions is made on the basis of human sound perception. This note arrives at the conclusion that capacitors do not add significant distortions to fundamental frequencies as they transfer signals. Modifications of the electrolyte or separation paper have almost no effect on the THD.

FAQ aluminium capacitors

Datasheet WCAP-CSRF

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.


  1. Würth Elektronik part number
  2. Actual ambient operating temperature which the capacitor is used at (°C)
  3. Operating ripple current flowing through the capacitor (A, RMS)
  4. Frequency of the ripple current (Hz)
  5. Operating voltage which is applied to the capacitor (V(DC))

Table shows the multiplier for ripple current vs frequency

Please find the following example (datasheet, page 2)

For all capacitors of series WCAP-A***, WCAP-P*** and WCAP-H*** there is a maximum ripple current in the datasheet. This ripple current is defined at a specific frequency and temperature and it is given as a RMS (root mean square) value.

Since the ripple current is defined at a certain frequency, it can be converted into the respective value for certain frequencies using factors. These factors can be found in the data sheet.

Let’s assume that the rated ripple current of this part (400V part) is 1 A @ 120 Hz. The max. ripple current @ max. temperature and 10 kHz is then 1.41 A.Furthermore, the ripple current can also be increased if the temperature is below the maximum component temperature. However, this must always be considered in the context of the expected lifetime.

The lifetime calculation in RedExpert can be used for a simple estimate. For detailed considerations, please use one of the many ways of contacting Würth Elektronik to obtain a specific lifetime estimate for your capacitor selection. This value may be increased or decreased if the operating conditions in the application are different from the datasheet.


Extract from the Lifetime calculator in Redexpert

You can find the lifetime calculation on REDEXPERT.

The lifetime calculator may be opened with the sand clock button in the left of the Electrolytic/Polymer/Hybrid . The user must be registered and logged, as this functionality is restricted to registered users.

You can set the conditions in the input box and for Frequency and Temperature you may also move the sliders in the graphs in the right.
