Aluminum electrolytic capacitors are polarized components that are typically used in power supplies. They are characterized by their extremely high capacitance and long lifespan. The B41505A4109M002 type aluminum electrolytic capacitor is a radial-leaded capacitor with a maximum temperature of 85°C. It is composed of aluminum, an electrolytic material, and a suction box. The series has an operating temperature range of -40°C to +85°C.

The B41505A4109M002 is used in a variety of applications, including filtering, decoupling, power conditioning, and noise suppression. It is also used as a timing capacitor and as a voltage divider. In addition, this capacitor is a common choice for power amplifier systems, voltage regulator circuits, and is commonly used in automotive power supplies.

Components

The main components of the B41505A4109M002 are the anode and cathode. The anode is made of aluminum foil, which is etched and coated with an electrolyte. The anode is then joined to the cathode, which is typically made of a highly conductive material such as carbon or a metal oxide. The anode and cathode are held together by a suction box, which maintains the electrical contact between them.

Working Principle

The working principle of the aluminum electrolytic capacitor is based on Faraday’s law of electrolysis. This law states that when a current flows through an electrolyte, the electrolyte is decomposed into its component ions. In an electrolytic capacitor, the electrolyte is decomposed into positively and negatively charged ions. The positively charged ions are attracted to the anode, while the negatively charged ions are attracted to the cathode. This action produces a charge on the capacitor, which can then be used to store energy.

In addition, the capacitance of the B41505A4109M002 is determined by the size of the anode and cathode and the thickness of the electrolyte. The capacitance is inversely proportional to the thickness of the electrolyte, and the larger the anode and cathode, the greater the capacitance.
