Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are widely used in power electronics industry. B41868A3478M belongs to a type of aluminum electrolytic capacitor. It has a number of advantages in terms of cost, size, and durability.

The B41868A3478M has a tight capacitance tolerance, a large capacitance value, and a very good thermal and electrical stability. Also, it can be used in a wide temperature range, from -55°C to +105°C. In addition, it has a high ripple current capability, which makes it suitable for power electronic applications such as SMPS or DC/DC converters.

Its applications can be found in DC/DC converter systems, motor speed controllers, power supplies, battery chargers, audio frequency amplifiers, and electronic ballast systems.

Regarding working principle, aluminum electrolytic capacitors are based on a principle similar to normal capacitors. A dielectric material is used between two electrodes, forming two electrical charges. However, instead of using a dielectric material like other capacitor, aluminum electrolytic capacitors use aluminum oxide as a dielectric material. The presence of the oxide layer on the aluminum creates a polarization on the surface which gives it the properties of a capacitor.

The B41868A3478M capacitor uses the Polarized Aluminum Electrolyte Technology that provides without any doubt the highest reliability available in the market: more than 20,000 hours load life at high temperature and with higher capacitance retention. This technology helps to reduce energy losses and to increase the efficiency of power applications.

Finally, aluminum electrolytic capacitors are an ideal choice for high frequency or ripple current applications as they provide very low ESL and ESR values. Moreover, they are available in a wide range of case sizes and capacitance values to meet all kinds of application requirements.
