Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors or super capacitors, are one of the most common type of capacitors used in electric circuits. EKXJ401ELL680KK40S is a type of aluminum electrolytic capacitor which has a number of advantages over other types. Its application field and working principle will be discussed in this article.

Application Field

EKXJ401ELL680KK40S aluminum electrolytic capacitors are designed primarily for power electronics applications such as LED lighting, inverter power supplies, motor control, and motor drive applications. The device features high temperature endurance and low equivalent series resistance (ESR) values, making it suitable for high power systems with a wide range of operating frequencies. The capacitors also have long life expectancy (up to 10,000 hours) and excellent temperature stability, making them suitable for applications requiring long-term reliability.

EKXJ401ELL680KK40S aluminum electrolytic capacitors are RoHS compliant, so they are suitable for use in all types of environmental conditions. The device is also available in different sizes and shapes, allowing for flexible designs and easy installation. Moreover, the device can withstand current interruption and high surge current, making it suitable for applications with transient high current and wide temperature range.

Working Principle

An aluminum electrolytic capacitor consists of two metal plates separated by a dielectric material. The inner core of the device is made of aluminum foil sprayed with an electrolyte. An anode material is sprayed onto the inner core. The two metal plates are connected by an electrolyte, forming a capacitive element with both electrical and mechanical properties.

During operation, a voltage is applied to the two plates, allowing current to flow through the electrolyte. As the capacitive element is polarized, positive ions flow from the positive side of the capacitor to the negative side. These positive ions react with the negative ions in the electrolyte, forming a layer of oxide on the surface of the electrodes. This layer of oxide serves as the dielectric material, acting as a barrier between the two electrolyte layers. As a result, the capacitance is determined by the size of the plates and the thickness of the oxide layer.

EKXJ401ELL680KK40S aluminum electrolytic capacitors have low equivalent series inductance, allowing it to filter out high frequency signals without significant losses. The device also has extremely smooth frequency response characteristics, making them suitable for wide frequency range applications.

In summary, EKXJ401ELL680KK40S aluminum electrolytic capacitors are an ideal choice for high power applications such as LED lighting, inverter power supplies, motor control, and motor drive applications. Their low equivalent series resistance (ESR) values, long life expectancy, and excellent temperature stability make them the perfect choice for a wide range of applications. The device’s ability to withstand current interrupts and high surge current also makes it suitable for applications with transient high current and wide temperature range.
