Aluminum electrolytic capacitors, also known as Al-Elec caps, are a type of capacitors that use a foil structure for an electrolytic anode separated by a non-polar dielectric layer, similiar to the foil design of a standard electrolytic capacitor. The anode is typically a two-layer design of a flat aluminum sheet and a thin oxide layer that is formed when a high-voltage AC signal is applied to the aluminum sheet. In contrast to standard electrolytic capacitors, the dielectric layer of a Al-Elec cap is non-polar, making them suitable for use in applications requiring stable capacitance and dielectric breakdown.

MAL211890535E3 is an aluminum electrolytic capacitor that uses a two-layer aluminum foil structure for its anode with an aluminum oxide dielectric. It has a very high capacitance of 8500μF, making it a good choice for power supply decoupling and noise filtering scenarios. It has a rated voltage (DC Voltage) of 35VDC and a rated ripple current of 5.5Arms (max). It comes in a small surface mount package size of 12.5*17.5*25mm, making it perfect for space-critical designs.

The working principle of an aluminum electrolytic capacitor is fairly simple. In the case of MAL211890535E3, the construction starts with the anode which is comprised of two layers of aluminum foil, with a thin layer of aluminum oxide dielectric between them. When an external voltage is applied to the anode, a high-voltage AC signal is generated, causing the aluminum oxide layer to form. This layer acts as an insulator and helps keep the current going through the anode stable.

When the capacitor is placed in a circuit, an electric field is created between the anode and the cathode. This electric field creates an attractive force between the opposite charges of the electrodes, forming an electric capacitance. This electric capacitance stores the electric charge, allowing electrical energy to be stored and discharged. By utilizing the different properties of the aluminum oxide layer, the amount of capacitance stored can be manipulated and adjusted accordingly.

MAL211890535E3 is used in many applications, such as filter circuits for power supplies or noise reduction circuits in audio applications. It is also used as a voltage regulator for LED lighting, as well as for controlling the speed of DC motors. It has a wide range of applications, as the large capacitance and high surge current rating make it suitable for many power related applications.
