Aluminum Electrolytic Capacitors: UHE2A270MPD Application Field and Working Principle

Aluminum electrolytic capacitors are a type of capacitor that uses an oxide film and two parallel electrodes to store energy by electrostatic action. They are widely used in a variety of applications, such as filtering high-frequency noise, signal coupling, and time-delay circuits. The UHE2A270MPD is the latest type of surface mount aluminum electrolytic capacitor manufactured by FDK Corp. This product is designed specifically for use in high-temperature automotive applications, such as engine control and power systems.

The UHE2A270MPD has a maximum rated voltage of 60V and a maximum rated temperature of 125 °C. It also features a low ESR (equivalent series resistance) of 0.1 Ohms, high capacitance of 270uF and a long life of up to 3300 hours. This combination of properties makes the UHE2A270MPD ideal for use in automotive systems that require high reliability, long life, and high power.

Working Principle

The working principle of the UHE2A270MPD is based on the basic concept of capacitance. It consists of two parallel plates separated by an insulating film. When an electric charge is applied to the plates, they accumulate an electric potential difference and an electric field is created between the plates. This electric field creates an electrostatic force that holds the charges on the plates, thereby storing energy. The larger the area of the plates and the dielectric material between them, the greater the capacitance and the more energy can be stored.

The UHE2A270MPD has a high capacitance, making it ideal for use in high-temperature applications. As the temperature increases, the ability of the capacitor\'s dielectric material to store energy decreases. Therefore, the UHE2A270MPD is designed with a solid oxide film that is able to function effectively in high-temperature environments.

The UHE2A270MPD also features a low ESR. This characteristic is important in automotive applications because a low ESR means that the capacitor is able to quickly respond to changes in voltage levels, helping to prevent voltage spikes and surges. The low ESR also enables the capacitor to release energy more quickly and efficiently, providing reliable power delivery in a wide range of operating conditions.

Another important feature of the UHE2A270MPD is its long life. The high-temperature environment of automotive systems can cause the capacitance of aluminum electrolytic capacitors to decrease over time. The UHE2A270MPD has a longer life than most capacitor types, making it ideal for use in extreme environments.

Application Field

The UHE2A270MPD is a popular choice for use in automotive applications, as it offers a combination of high capacitance, low ESR, and long life, making it an ideal choice for high-temperature environments. Typical automotive applications for the UHE2A270MPD include engine control systems, power steering systems, airbags, and traction control systems. It is also commonly used in various other industrial and consumer applications, such as LED lighting and power supplies.

The UHE2A270MPD is also suitable for other high-temperature environments, such as medical electronics, as it is able to handle extreme temperatures without jeopardizing its performance. It is also often used in home appliance and instrumentation applications, as well as in motor control systems and acoustic systems.

The UHE2A270MPD is a great choice for applications that require high performance, long life, and reliability. Its combination of high capacitance, low ESR, and long life makes it an ideal choice for a wide range of automotive and other high-temperature applications.
