EGXF500ELL152MK40S

Aluminum electrolytic capacitors are types of capacitors that use electrolytic action to achieve a much higher capacitance than other types of construction. They are utilized in many applications, ranging from small decoupling capacitors in consumer electronics to the huge filtering capacitors in DC power supplies or HID lighting ballasts. With the appearance on the market of the EGXF500ELL152MK40S, Aluminum electrolytic capacitors have achieved a new level of performance. In this article, we will explore its application fields and its working principle.

The EGXF500ELL152MK40S is an upgradable aluminum electrolytic capacitor with a high energy density in a low impact SMD package. It excels in areas requiring efficient energy storage and management, such as electronic control systems, power factor correction and power conversion systems. Its unique design means that it can be used in a wide variety of applications as an alternative to traditional, inefficient electrolytic capacitors.

In terms of capacity and voltage ratings, the EGXF500ELL152MK40S is rated for operating up to 2 million uF and for a maximum voltage of 250 VDC. Combined with its 6114 mm3 volume, this makes it one of the most efficient capacitors ever designed. The advantages of the capacitor do not stop there though, as it also offers a low equivalent series resistance (ESR) of only 0.08 Ω at 100 kHz, making it ideal for power factor correction and high frequency applications.

As for features, the EGXF500ELL152MK40S is equipped with a novel conductive polymer cathode which eliminates evaporation and contact with harmful electrolyte. This allows the capacitor to operate stably and reliably at all temperatures and conditions. It is also designed for a long lifetime, up to 10 000 hours at a rated voltage. It has an operating temperature range of -25°C to +85°C, allowing it to be used in a wide range of ambient temperatures.

The working principle of the EGXF500ELL152MK40S is quite straightforward. It is based on an electrolytic action, where a positive electrolyte is pumped through tightly wound aluminum foils that are separated by a dielectric. When a positive potential is applied to the anode, the electrolyte attacks the surface of the anode and forms an insulating layer of oxide on it. The dielectric thus created between the anode and the cathode is called an electric double layer. The capacitance of the capacitor is determined by the ratio of the thickness of the dielectric layer to the area of the plates. The EGXF500ELL152MK40S uses a high-performance conductive polymer cathode that eliminates contact with harmful electrolyte while providing a higher capacitance and better long-term performance.

In conclusion, the EGXF500ELL152MK40S is intended for high-energy applications such as electronic control systems, power factor correction and power conversion systems. It is capable of handling high voltages and offers a high energy density in a compact SMD package. With its novel conductive polymer cathode, this part offers improved performance and a longer life. Its working principle is based on an electrolytic action, where a positive electrolyte is directed through tightly wound aluminum foils that are separated by a dielectric. Thanks to its numerous advantages, the EGXF500ELL152MK40S is an ideal choice for modern power systems.
