Aluminum Electrolytic Capacitors

B43508E2128M60 application field and working principle

Aluminum electrolytic capacitors are an electrical component similar to other capacitors and are commonly used in electronic circuits. Aluminum electrolytic capacitors are constructed from an aluminum foil along with its oxide layer which conducts electric current. When a voltage is applied across its terminals, the electric field across the layers sets up a flow of current, thus allowing electrical energy to be stored within the capacitor.Aluminum electrolytic capacitors are mostly used for applications requiring higher capacitance values and especially those with long life cycles and low leakage current. These capacitors are widely used in power supplies, switching power supplies, consumer electronics, industrial and commercial electronics, medical equipment, and appliances. The B43508E2128M60 aluminum electrolytic capacitor from EPCOS is the highest capacitance aluminum electrolytic capacitor in the world. The product is designed for highly sophisticated applications. It features a extremely long life of 10,000 hours at 105 °C and high capacitance on low profile of 8 x 25.3 mm. It uses a radial 5 mm lead pitch and is available with square or circular cross-sections.It is a polarised electrolytic capacitor, as it contains an electrolyte, which enables it to operate at much higher capacitances than most other capacitors. Its two plates are made of aluminum, which gives it a superior capacitance-to-volume ratio than many other types of capacitors.The B43508E2128M60 is usually used to supply large amounts of power within switching power supplies, inverters, and other circuits that require large capacitance and high life cycles. The capacitor is able to withstand high ripple currents and surges due to its long-life characteristic. The capacitor is also RoHS compliant, making it suitable for use in all environment. The B43508E2128M60 operates on the principle of a double layer system, where one layer is composed of an electrolyte containing ions, and the other layer is a dielectric oxide film with stored ions. When the voltage is applied across its terminals, an electric field is set up which in turn will cause the ions to move towards the electrodes and adsorb onto the surface of the electrode plates. This process then results in the formation of the electrical double layer, which stores an electric charge in form of an energy field, thus allowing the capacitor to store energy.In conclusion, the B43508E2128M60 aluminum electrolytic capacitor from EPCOS is a high performing capacitor mainly used in power supply and switching power supply applications. It features an extremely long life of 10,000 hours at a certain temperature and high capacitance on low profile. It is also RoHS compliant, making it suitable for all environment.
