Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most widely used and reliable type of capacitors available. They are a form of electrolytic capacitor, made up of two conducting plates, an electrolyte (typically in the form of an alcohol-based nonaqueous liquid), and a semi-permeable membrane. They are most commonly used in applications where a stable voltage and high capacitance value are desirable.

HR101471T250BB2B Application Field and Working Principle

The HR101471T250BB2B is an aluminum electrolytic capacitor which has a nominal capacitance of 1,471µF, a tolerance of ±20%, a rated voltage of 10V, and a temperature range of -40°C to +85°C. It is encapsulated in a radial, can-style plastic case, with a lead pitch of 2.5mm. These capacitors are used in a variety of applications, such as power supplies, motor drive circuits, and timer circuits.

The working principle of an aluminum electrolytic capacitor is based on Faraday’s Law of Electrolysis, which states that when a charge is applied to one plate of a capacitor, a current is induced in the electrolytic solution, driving the charge to the other plate. This process forms an electrolytic reaction, resulting in a capacitance. As the plates become more charged, the capacitance increases.

The primary advantages of aluminum electrolytic capacitors are their high capacitance values, low equivalent series resistance (ESR), and wide operating temperature range. They also have a high volumetric efficiency which allows them to be used in small size applications. However, they have some disadvantages, such as generally lower reliability and shorter life than other types of capacitors, and their high sensitivity to temperature and humidity.

Aluminum electrolytic capacitors are more expensive than other types of capacitors, but their long life and high level of performance make up for the higher cost. They are valuable components in many applications and should be carefully selected for each design, considering their suitability for the intended operation.

In conclusion, the HR101471T250BB2B aluminum electrolytic capacitors are a suitable choice for many applications, such as power supplies, motor drive circuits, and timer circuits due to their high capacitance values, low ESR, wide operating temperature range, and high volumetric efficiency. They offer reliable performance but have some drawbacks, such as lower reliability and shorter life than other types of capacitors, and their high sensitivity to temperature and humidity. Careful consideration should be given to each application before making a selection.
