Aluminum Electrolytic Capacitors (AEC) are one of the most common type of electrolytic capacitors used in industrial and consumer electrical device applications. They are typically composed of an etched aluminum foil, sandwiched between two porous plates that are usually impregnated with an electrolyte solution. AECs are used to provide short and long-term storage for a charge that can be used to regulate power delivery. They have good electrical performance, stability, and robustness, and are used in a wide range of applications and environments. This article will focus on the application field and working principle of the EKY-250ELL471MH20D AEC.

The EKY-250ELL471MH20D is a high-capacitance, low ESR AEC with a high ripple current and a large temperature range. It can be used in a variety of applications, including automotive batteries, power supplies, industrial automation and control, and telecommunications. It is very reliable in long-term and heavy-duty applications due to its excellent electrical performance and robustness. The EKY-250ELL471MH20D is able to withstand high voltage and temperature ranges, making it ideal for use in extreme environmental conditions.

The EKY-250ELL471MH20D has a rated capacitance value of 250 uF and an ESR of 471 mOhms. It has a temperature range of -55°C to +125°C and a maximum operating voltage of 4.2V. The EKY-250ELL471MH20D also features a high ripple current of 85 mA at 10kHz and a rated leakage current of 5 uA. In addition, it has a long-term stability of 0.1 %/1000 hours and a maximum capacitance tolerance of + or - 5%.

The working principle of AECs can be explained by the electric double-layer theory. When an electric potential is applied across the capacitor, electrons from the positive and negative terminals migrate to the negative and positive layers of the porous plates respectively. During this process, the electrons are attracted by the electric field and accumulate along the surface of the plates. As the charge accumulates, more electrons build up on both surfaces and create capacitance. This capacitance is the main cause of the current storage provided by the capacitor.

The EKY-250ELL471MH20D also increases its capacitance value in the presence of a grid-tied electrical system or other equivalent electric charge sources. This is done by utilizing the energy stored in the energy storage capacitor connected to the input source. When a grid-tied system is present, the energy stored in the capacitor is used to supplement the primary source of power, resulting in a reduced load on the power plant. This increased capacitance also results in increased charge efficiency, providing a higher power delivery performance.

The EKY-250ELL471MH20D is a reliable and robust AEC that is suitable for a variety of applications. With its high ripple current, good electrical performance and temperature range, it is able to withstand harsh conditions and provide a reliable power source for a wide range of applications. The EKY-250ELL471MH20D has also been designed to provide increased charge storage capacity in grid-tied electrical systems and other equivalent electric charge sources, ensuring its value as a reliable and robust power storage device.
