Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, often known simply as electrolytic capacitors, are polarized capacitors which use an electrolyte to obtain higher capacitance than possible with standard dielectric films. They are mainly used in applications where large capacitance is needed, such as in power supplies or audio equipment.

B43601F2687M80

The B43601F2687M80 is an aluminum electrolytic capacitor from Panasonic. It is an industrial grade, non-solid-type capacitor with the capability to withstand a ripple current up to 1.13A. This makes it suitable for use in high-end equipment with heavy loads and high electric current. The maximum operating temperature is rated at 105°C.

Application Field

The B43601F2687M80 is primarily used in DC link capacitors, DC link snubbers, high-efficiency converters, DC/DC converters, audio amplifiers, and other general circuit applications. It is also suitable for heavy-duty applications such as motor drives, aircraft, and other kinds of transportation systems and equipment.

Working Principle

Aluminum electrolytic capacitors work through two oppositely charged plates separated by an electrolyte. The plates are typically made of aluminum and are called anodes. The electrolyte is a liquid or gel-like substance which contains ions. When a voltage is applied across the plates, electrical current flows through the electrolyte. This current causes the ions to migrate, leaving behind an accumulation of electrons on one of the plates, creating a charge difference between the two plates.

The charge difference between the two plates produces an electric field that increases the capacitance of the capacitor. This process is known as “electrochemical polarization” and is responsible for the high capacitance of aluminum electrolytic capacitors. The electrolyte also provides a “self-healing” effect which protects the capacitor against mechanical damage such as vibration or shock.

In summary, the B43601F2687M80 is an aluminum electrolytic capacitor from Panasonic. It is primarily used in applications requiring high capacitance and ripple current and is suitable for heavy-duty applications as well. The capacitor works through electrochemical polarization of two oppositely charged aluminum plates separated by an electrolyte.
