Aluminum Electrolytic Capacitors

ULD2G6R8MPD Application Field and Working Principle

Aluminum electrolytic capacitors are an important part of the electronic system. They are widely used in the fields of power supply, weapons, instrumentation, and telecommunications. ULD2G6R8MPD is a capacitor product of aluminum electrolytic capacitor which applies to military and medical fields. This article will discuss its application field of ULD2G6R8MPD and its working principle.ULD2G6R8MPD is an aluminum electrolytic capacitor utilizing non-solid electrolyte consisting of a solid manganese dioxide cathode, a thick PVC separator and a dielectric, anhydrous aluminum oxide film, and a metal-oxide sealed can. It is used for the purpose of storing energy in a circuit for a short period of time. Its application ranges from power supply, military, instrumentation to telecommunications. ULD2G6R8MPD features high temperature operation of 105℃, low ESR, large capacity and long service life, making it popular in the medical fields.To understand the working principle of this capacitor, one should first understand the structure of its components. The aluminum electrolytic capacitor consists of five main components, namely, the anode, the dielectric oxide film, the separator, the cathode, and the electrolyte. The anode of the capacitor is made up of thin aluminium foil which has been etched to form an extremely thin layer called the oxide film. This oxide film works as the capacitor’s dielectric and allows charge to pass through it, creating an electrical field between two conductors placed adjacent to each other. The separator is made up of a thick layer of PVC material which insulates the anode and cathode of the capacitor, enabling it to store electrical energy. The cathode is made up of a solid manganese dioxide material, which allows current to pass through and discharges the electrical energy. Finally, the electrolyte allows ions to move between the anode and cathode in order to distribute charge.When a voltage is applied to the capacitor, the anode attracts the positive ions to it and the cathode attracts the negative ions. This causes the oxide film, the dielectric, to become charged, thus creating an electrical field between the two conductors. As the voltage level is increased, the dielectric film becomes thicker, leading to an increase in the capacitance. In addition, a leakage current will also flow through the capacitor as the dielectric film becomes more conductive. To summarize, the ULD2G6R8MPD is a aluminum electrolytic capacitor with a non-solid electrolyte designed for the purpose of storing energy in a circuit for a short period of time. It is mainly used in the military, medical and telecommunications fields because of its high temperature operation of 105℃, low ESR, large capacity and long service life. Furthermore, the working principle of the capacitor can be explained as the anode attracting the positive ions, the cathode attracting the negative ions and the dielectric becoming thicker as the voltage level is increased.
