Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are one of the most widely used types of capacitors in today’s electronics. Also known as electric double layer capacitors (EDLs), they are highly efficient components mostly utilized for their excellent high frequency and low-frequency characteristics. With their advantageous features, AECs are vastly employed in filters, decoupling, memory control circuits, timers and AC power supplies.

B43564B4478M000 Application Field and Working Principle

The B43564B4478M000 is a surface-mounted aluminum electrolytic capacitor. It is a popular choice for different applications, given its wide temperature range from -55 to +125°C. It is also equipped with high-temperature reverse current capability making it suitable for various types of electronic circuits. One of the most significant benefits is the small size, which makes it the ideal fit for limited space boards.

AECs use chemical reaction to store electricity. The electrolyte inside of the capacitor ceases an anode and a cathode, creating a barrier that prevents an electric current from passing through. On the cathode side, oxygen molecules are formed, which bind with the anode material such as aluminum. The oxygen molecules act as a barrier and prevent electric current from passing through. This process is reversed when a voltage is applied to the electrodes, allowing the current to flow.

By utilizing the physical properties of charged surfaces and internal structure of electrolytes, AECs are able to store large amounts of energy in a small space, which makes them suitable for a wide range of applications. The process of storing charge happens in moments and is repeated as long as a voltage supply is available, making AECs one of the most efficient and reliable components used in modern electronics.

Besides extra-long life and high reliability, AECs are great for high-frequency applications due to their superior self-healing property, low ESR and impressive high ripple current capability. This makes them quite popular in applications that require high levels of energy tolerances.

The B43564B4478M000 is an efficient and capable aluminum electrolytic capacitor. It offers various benefits while delivering superior performance. Its wide temperature range and its high-temperature reverse current capability makes it suitable for a range of electronic applications, such as decoupling, filters, timers, memory control circuits and AC power supplies.
