  • Aluminum Electrolytics

    Delivering the highest capacity values of all capacitor families (up to 2.2 Farads), these components are widely used in filtering, energy storage, energy sourcing and motor power supply units.

  • Searching for a product with Large Capacitance?

    Aluminum electrolytic capacitors, also commonly known as just electrolytic capacitors, are a unique type of configuration that uses an electrolyte to achieve a capacitance that is much larger than other types of these devices. The electrolyte in question is usually either a gel or a liquid that itself contains a very high concentration of polarized ions. Polarization indicates that the voltage on the positive terminal is always larger than the similar voltage on the negative terminal of the capacitor.

    One of the major benefits of these types of aluminum electrolytic capacitors is the aforementioned large capacitance. They do, however, have a number of disadvantages when compared to other types of capacitors. Aluminum electrolytic capacitors have a large leakage current when compared to capacitors of other types. Additional disadvantages include a limited lifetime, value tolerances and an equivalent resistance series.

  • Wet Electrolyte versus Solid Polymer

    Aluminum electrolytic capacitors can be produced using either a wet electrolyte or a solid polymer material, depending on the needs of the producer and the types of applications that the capacitor will be used for. In addition to aluminum electrolytic capacitors, electrolytic capacitors can also be made from a tantalum material or other types of materials.

  • Double-Layer Super Capacitors

    Another common type of aluminum electrolytic capacitor is called a double-layer electrolytic capacitor, which is also commonly known as a super capacitor. These types of devices are capable of hundreds of thousands of farads depending on the specific application in question. Aluminum electrolytic capacitors in general have a large number of different uses throughout various electronic devices, many of which you probably have in your home right now. Types of applications for these capacitors can include use in domestic appliances like refrigerators or microwaves, use in power supplies, use in desktop or laptop computer motherboards and more. However, aluminum electrolyte capacitors can only be used in direct current circuits due to the fact that they are polarized.

  • Why are Electrolyte Capacitors Forward Biased?

    For the purposes of safety, these types of capacitors need to be forward biased in their configuration. This is mainly due to the characteristics of the electrolyte that has been used in their construction. The positive terminal always needs to have a larger amount of voltage than that of the negative terminal. If the situation were reversed and the negative terminal suddenly had a higher voltage than the positive terminal (which is also referred to as reversing the voltage polarity), the aluminum material that is used as the dielectric could short circuit and become damaged. It could also overheat, which could cause a substantial leak. The capacitor could also vaporize, which could cause the entire enclosure to burst under the right circumstances. It is important to note, however, that this phenomenon is very rare.
