Aluminum Electrolytic Capacitors

As the name implies, aluminum electrolytic capacitors are a type of capacitor that uses aluminum as one of its main components. Generally, these capacitors are made up of two thin aluminum foils, immersed in an electrolyte bath, and separated by a paper separator for insulation. Aluminum electrolytic capacitors offer high capacitance values in a small device profile, making them a popular choice for many electronic applications.

The B41828A2686M is an aluminum electrolytic capacitor specifically designed for surface mount applications. It has a maximum capacitance of 18uF and a maximum operating temperature of 105°C. It can operate in AC/DC applications between a frequency range of 20kHz to 1MHz.

Application Field

Aluminum electrolytic capacitors with low capacitance (1uF to 39uF) are mainly used in AC and DC filters, LCD televisions, voltage stabilizers, energy saving lamp ballast, and automotive electronics, while capacitors with medium capacitance (40uF to 470uF) are mainly used for energy storage in automotive electronics, UPS and power supplies, etc.

Working Principle

The working principle of aluminum electrolytic capacitors is based on the phenomenon of electrolysis. When a voltage is applied between the two electroly have obtained a type of capacitor with a large capacitance and a non-polar structure. When the applied voltage is greater than the rated voltage, the electric field between the plates will break the film covering the anode and the polar molecules in the electrolyte will be electrochemically decomposed, resulting in a large current and self-heating, which destroys the capacitor.

The B41828A2686M aluminum electrolytic capacitor utilizes a special etching process, which reduces the equivalent series resistance and increases the dynamic stability for higher frequency applications. This makes it an ideal choice for high performance circuits. The device also features low impedance and high frequency characteristics, making it especially suited for use in audio crossover networks.

Aluminum electrolytic capacitors are a valuable component in many applications and can be found in most modern electronics. The B41828A2686M is a high quality, reliable capacitor, designed for high performance applications. Its features make it an ideal choice for many types of applications.
