Aluminum electrolytic capacitors, also known as “dry” or solid electrolytic capacitors, constitute an important component in countless industrial, commercial and consumer applications. B43508A2108M7 is a type of aluminum electrolytic capacitor produced by Infineon Technologies AG. This particular capacitor is characterized by its high temperature applications, very low ESR and very long life and makes it suitable for high power electronic systems.

The B43508A2108M7 aluminum electrolytic capacitor has many application fields. It is often used in DC-DC converters, motor controls, automotive systems, LED lighting, and energy harvesting systems. One advantage of a B43508A2108M7 capacitor is that it has a wide temperature range, allowing for its use in applications across a variety of climates and temperatures. In addition, it is designed to meet the IEC standard for surface mounted aluminum electrolytic capacitors and is compliant with the Restriction of Hazardous Substances (RoHS) directive.

The chemical makeup of the B43508A2108M7 aluminum electrolytic capacitor is comprised of an anodic foil oxide, two electrolytes, and a metal case. The anodic foil oxide is primarily composed of aluminum or tantalum and allows for charge to be stored. The electrolytes allow ions to migrate between the anodic oxide and the metal case. Finally, the metal case helps to provide a physical structure for the components.

The working principle of a B43508A2108M7 aluminum electrolytic capacitor is relatively simple. Positive charges are attracted to the anodic oxide and negative charges are attracted to the metal case, forming a polarized capacitor. When a direct current is applied to the capacitor, positive ions from the electrolytes move towards the anodic oxide layer and negative ions move towards the metal case. This accumulates negatively charged electrons on the anodic oxide layer and positively charged electrons on the metal case.

The magnitude of the current and the time it is applied to the capacitor determines the amount of charge stored by the capacitor. Once the capacitor has reached its full charge potential, if a higher voltage is applied, the capacitor will become saturated and excess energy is dissipated as heat. When the voltage applied to the capacitor drops, the current reverses and the capacitor begins to discharge. This process continues until the capacitor is completely discharged or shorted out.

In conclusion, the B43508A2108M7 aluminum electrolytic capacitor is an important type of capacitor for many different electronic systems. Its applications span multiple industrial, commercial, and consumer sectors due to its low ESR and wide temperature range. The chemical makeup of the capacitor consists of an anodic oxide layer, two electrolytes, and a metal case. The working principle of the capacitor is based on the attraction of positive charges to the anodic oxide layer and negative charges to the metal case, forming a polarized capacitor.
