Aluminum electrolytic capacitors (AECs) are non-polarized capacitors that are commonly used in a variety of applications including lighting, power supplies, motor drives, and medical applications. The MAL212016472E3 capacitor is a type of AEC specifically designed for applications requiring high-voltage, low-ripple capacitance. This article will discuss the application field and working principle of the MAL212016472E3 AEC.

The MAL212016472E3 AEC is a designed for applications needing high-voltage capacitance up to 1600 VDC. It has a wide operating temperature range of -55⁰C to +105⁰C and a long life expectancy of up to 2,000 hours at the rated temperature of 85⁰C. The MAL212016472E3 has a low equivalent series resistance (ESR) and is highly stable over a wide range of temperatures.

The MAL212016472E3 is typically used in various circuit applications including power supplies, lighting, and motor drives. It can also be used in medical equipment, and other high-voltage and high-temperature applications. The large capacitance, due to the use of low ESR in this AEC, can be used to filter out unwanted frequencies and to provide a more stable voltage in the power supply. It also helps prevent premature failure of the system due to overvoltage or overcurrent conditions.

The internal construction of the MAL212016472E3 AEC is composed of two main components: the anode and the cathode. The anode is made of aluminum foil which is coated with a thin film of oxide and metallized to meet the specification requirements. The cathode is made of aluminum foil which is coated with electrolyte and a separator to ensure insulation between elements. This design ensures that the current density of the capacitor is low, thus improving its stability under harsh environmental conditions.

The working principle of MAL212016472E3 is based on the principles of electrochemical reaction. The anode and the cathode are both immersed in an electrolyte. When a voltage is applied, the ions in the electrolyte start to flow from the anode to the cathode. This flow creates a potential difference between the anode and the cathode, and this causes a current to flow. The current causes an electrochemical oxidation/redox reaction on the anode, which in turn stores the energy as electric charge.

The MAL212016472E3 AEC is not suitable for every application and must be carefully evaluated to ensure that it will meet the requirements. However, it offers high capacitance in a small package, low ESR, and stable performance over wide temperature requirements for power supplies, lighting, motor drives, and medical applications.
