Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are special types of capacitors that store electrical energy and are used in a wide variety of applications. The most common type of aluminum electrolytic capacitor is a polarized one, where two metal electrodes are separated by a dielectric separator, typically either a sheet of paper or a thin film. This type of capacitor is widely used in consumer electronics, power supplies, and in some industrial applications.

B43455B5338M7 application field and working principle

The B43455B5338M7 is an aluminum electrolytic capacitor, made up of aluminum and paper separators. The aluminum foil acts as both the positive and negative electrodes, with each layer separated by the dielectric. Its components are completely sealed in a cylindrical can, making them highly resistant to external influences. This type of capacitor is used mainly in power supplies, motor starters, and various other electronics.

The working principle of an aluminum electrolytic capacitor is based on the physical principle of “electrostatic charge”. When an electric current runs through the capacitor, a positive charge is built up on the capacitor’s anode (positive electrode), and a negative charge builds up on its cathode (negative electrode). This creates an electric potential in the capacitor, which is basically stored energy.

The capacitor’s two terminals are connected in parallel to a power supply. When the power is switched “off”, the electric charge stored in the capacitor is discharged and the power supply is disconnected. This makes the capacitor an ideal component for power supplies, motor starters and DC motor control, as it can be used to control current and voltage in these systems.

In terms of size, the B43455B5338M7 measures 8mm in diameter and 18mm in height. It has a rated capacitance of 470uF at a rated voltage of 16V and a rated temperature of -40°C to +85°C. It also has a self-healing characteristic, meaning it will automatically repair itself if it becomes damaged due to aging or over voltage.

The B43455B5338M7 is a versatile aluminum electrolytic capacitor that can be used in a wide range of applications. Its size and self-healing capability make it ideal for use in power supplies and motor starters, while its high reliability and long life make it suitable for use in consumer electronics, automotive applications, and industrial applications.
