Aluminum electrolytic capacitors are polarised electrolytic capacitors whose anode electrode is made of a pure aluminum foil with an oxide layer acting as the dielectric. Its advantages include long life, high capacitance, low cost, and large voltage handling characteristics. The main application fields are: motor drives, UPS, telecom supplies, high power audio amplifiers, automotive electronics, high voltage switching, and flash and strobe lighting.

The B43564A5828M7 aluminum electrolytic capacitor (also referred to as a bipolar aluminum electrolytic capacitor) is one of the most popular and reliable capacitors in the market. It is a low-ESR (Equivalent Series Resistance) and high-current aluminum electrolytic capacitor with radial leads and a maximum temperature range of 105oC. The product is RoHS compliant and free from hazardous substances.

The B43564A5828M7 is designed to provide high capacitance and reliability level along with low ESR for its given size. It features high ripple current ratings and is capable of withstanding voltage ratings from 6.3VDC to 450VDC. The life expectancy of the capacitors is typically up to 5000 hours at 105oC, making them suitable for a wide range of high temperature applications. This reliability along with its small size has made this type of aluminum electrolytic capacitor indispensable for a wide range of applications.

The working principle of aluminum electrolytic capacitors is based on the movement of ions in a solution of dissolved salts. When an electrolytic capacitor is constructed, the metal anode is separated from a porous dielectric material in the form of a layer of oxide or carbon, which serves as a spacer. When a voltage is applied across the device, ions from a solution of electrolyte are attracted to the anode surface and deposit on the oxide layer, thus creating an electrical charge. This charge, in turn, acts as a barrier, preventing further ion migration, and thus creates a storage capacitor.

The ions on the anode layer also serve to increase the capacitance of the device. As the anode and dielectric layers are thin enough, a high capacitance can be achieved within a fairly small physical size. As the charge is stored indefinitely, aluminum electrolytic capacitors will retain their electrical properties for long periods, making them very suitable for long-term energy storage.

Overall, the B43564A5828M7 aluminum electrolytic capacitor is an ideal choice for applications that require high capacitance and other features such as good reliability and good temperature range. It is also a cost-effective solution when compared to other types of capacitors and is becoming increasingly popular for a wide range of embedded and power electronic applications.
