EEF-UD0D391ER

Aluminum - Polymer Capacitors are designed to have a very long life and high capacitance, while minimizing self-discharge. The EEF-UD0D391ER is an example of this type of capacitor. It has an operating temperature range of -40ºC to +105ºC and a rated voltage of 250V. It has a tolerance of 5%.

The main use of the EEF-UD0D391ER is as a decoupling capacitor in power electronics and power circuits. A decoupling capacitor is used to reduce or eliminate voltage fluctuations or noise on a power source by "smoothing" the current flow. It is also used to control inrush current and in harmonic suppression.

The EEF-UD0D391ER is designed to have very low leakage currents and natural resonance frequencies. Its capacitance is also very stable and makes it well suited for resonant applications. The EEF-UD0D391ER has an excellent temperature coefficient of capacitance and can be used in environments with extreme temperatures.

One of the key benefits of the EEF-UD0D391ER is its ability to provide a High Energy Density (HED) Capacitance. This means that it has a much higher storage capacity than standard aluminum electrolytic capacitors. This higher capacity allows for a more compact and efficient design and helps to reduce heat dissipation, which ultimately prolongs the life of the capacitor.

The EEF-UD0D391ER has two layers of electrodes. The top layer is made of aluminum, while the bottom layer is made up of a polymer film. When a voltage is applied to the electrodes, a field is created between them and electrons move between them, creating a capacitance. By using a dielectric material with a low permittivity, such as polymer film, the capacitance is increased and the self-discharge is reduced. This helps to make the EEF-UD0D391ER a reliable and durable capacitor.

The EEF-UD0D391ER is a reliable and durable aluminum-polymer capacitors that has a variety of uses in power electronics and power circuits. It has excellent characteristics such as a high energy density and a low self-discharge, as well as a very stable capacitance. It is well suited for resonant applications and can be used in environments with extreme temperatures.
