The E81D250VNN273MR50T is a popular type of aluminum electrolytic capacitor and can be used in a range of applications. In this article, we discuss the application field and working principle of the E81D250VNN273MR50T.

Application Field of E81D250VNN273MR50T

The E81D250VNN273MR50T is a radial leaded aluminum electrolytic capacitor which is typically used for switching power supplies, DC-DC converters, electronic ballasts, and conversion of direct current (DC) to alternating current (AC). Its key features include a rated capacitance of 273μF, a rated voltage of 250V, and high ripple current capabilities. The E81D250VNN273MR50T is capable of operation at temperatures ranging from -55°C to +105°C and is RoHS compliant.

The capacitor is available in a variety of package sizes including the OH35, OH50, OH60, OH65, OH75, and OH100, each of which is designed to provide different levels of performance. The OH35 is the smallest package size and is ideal for applications where space is limited. The OH100 is the largest package size and is typically used for applications with higher power requirements.

Working Principle of E81D250VNN273MR50T

The E81D250VNN273MR50T utilizes aluminum electrolytic technology to store electrical energy. This type of capacitors is constructed with two aluminum foils separated by a dielectric material, such as paper or plastic, with an electrolyte in between. The aluminum foils act as the two electrodes and the electrolyte provides the ionic charge carriers that allow the capacitor to store electrical energy.

When a voltage is applied between the two electrodes, an electrical current is generated which flows through the electrolyte. This current causes ions to be attracted to the negative terminal and attracted to the positive terminal. The ions are then added to the aluminum foil electrodes, increasing the capacitance of the capacitor and reducing the voltage difference between the two terminals.

The E81D250VNN273MR50T is designed to be stable under harsh environmental conditions. The aluminum casing of the capacitor provides improved heat dissipation and prevents it from being damaged due to high currents. The incorporating of a self-healing mechanism also help to ensure the durability of the capacitor.

In conclusion, the E81D250VNN273MR50T is a popular type of aluminum electrolytic capacitor that is used in various applications due to its low cost and high performance. The capacitor utilizes aluminum electrolytic technology to store electrical energy and is designed to be stable under harsh environmental conditions. The E81D250VNN273MR50T is available in a variety of package sizes, ranging from OH35 to OH100.
