Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are capacitors with a certain amount of electrolyte in the gap between two electrodes. The material of the electrodes is aluminum foil, and the active material is aluminum oxide film formed after the gap is anodized. In addition to providing capacitance, it also provides good self-healing properties, allowing the capacitor to recover even after damage.

The B43511C0687M000 is an aluminum electrolytic capacitor with a rated capacitance of 4.7uF and a rated voltage of 85. It has an operating range of -40°C to +85°C, and a rated ripple current of 82mArmp. The capacitor is made from stainless steel and is extremely durable, with a service life that can reach up to 2000 hours under full load.

The most common application for B43511C0687M000 is power supply filtering and energy storage. It is also suitable for noise and signal filtering, timing, and delay applications. It is applicable to buck boost converters, DC-DC converters, and other electronic circuits. The capacitor is widely used in the automotive industry, and is also used in many consumer electronics products, such as mobile phones, LCD monitors, and other electrical devices.

The working principle of B43511C0687M000 is based on the principle of electrochemical polarization. During operation, the positive electrode of the capacitor is connected to the positive DC voltage, while the negative electrode is connected to the negative DC voltage. When the capacitor is charged, a current passes through the capacitor and the electrolyte. This current passes through the aluminum oxide layer, which causes the layer to become thicker. This increased thickness of the oxide layer creates an electrical barrier between the two electrodes, reducing the current flow through the capacitor and reducing the capacitance.

When the voltage across the capacitor is reversed, the negative ions in the electrolyte move towards the positive aluminum foil, and the oxide layer becomes thinner. This causes an increase in current flow and the capacitance increases. This process occurs repeatedly when the capacitor is under load and the capacitance changes accordingly.

Due to its excellent performance and robust design, the B43511C0687M000 is widely used in a variety of applications. Its low leakage current and high temperature endurance make it suitable for many power supply filtering and energy storage applications, and its excellent ripple current capabilities make it suitable for noise and signal filtering, timing, and delay circuits. It is an ideal choice for many applications where reliable performance is required.
