Aluminum electrolytic capacitors, also known as electrolytic capacitors, aluminum capacitors or electro-lytics, are a type of polarized capacitor whose anode electrode is composed of an aluminum foil laminated with a coating of anodic oxide layer. These capacitors are characterized by large capacitance in a small volume. The ECE-A1HKG3R3 variant of aluminum electrolytic capacitor is an excellent and cost effective capacitor solution, typically employed in a variety of applications in many different industries.

Application Field: The ECE-A1HKG3R3 aluminum electrolytic capacitor is primarily used in lighting, uninterruptible power supply (UPS), automotive electronics, and telecom applications. In lighting applications, it is commonly used for the start circuit of discharge lamps, like high power HID lamps and LED panels. It is suitable for temperature ranges from -40°C up to +105°C, and thanks to its low-ESR characteristics, it shows excellent tolerance to pulsating operations. The combination of high capacitance, low ESR, and acceptable temperature range makes it ideal for applications in telecom, uninterruptible power supplies, and railway signaling systems.

Working Principle: The working principle of aluminum electrolytic capacitors is based on Faraday’s Law of Electromagnetic Induction. This law states that the current in a circuit is proportional to the rate of change of the magnetic field in the circuit. In the case of aluminum electrolytic capacitors, the rate of change in the magnetic field is caused by the electric charge that is passed through the capacitor. This electric charge is stored in the form of an electric field, and this field is responsible for the capacitance of the capacitor.

The anode of an aluminum electrolytic capacitor consists of a conductive medium (aluminum) covered with a thin layer of anodic oxide. This layer acts as the dielectric material for the capacitor, and it is responsible for the storage of electrical charge by modulating the electric field in the capacitor. The cathode surface of the capacitor consists of a solid electrolyte, such as a solution of aluminum chloride, through which the stored electrical charge passes and is neutralized.

The capacitance of the aluminum electrolytic capacitor is determined by its geometrical factors, such as the anode and cathode areas, and the thickness of the anodic oxide. The ECE-A1HKG3R3 variant offers capacitance values up to 1000uF, with an operating voltage of 350V.

In conclusion, the ECE-A1HKG3R3 aluminum electrolytic capacitor is a highly versatile and cost-effective capacitor solution, suitable for a wide variety of applications. It offers high capacitance values, good tolerance to temperature changes, and low-ESR characteristics, all in a small package.
