Aluminum electrolytic capacitors are common components used in many consumer and industrial electronics. EGXF251ELL680MK30S is one such aluminum electrolytic capacitor that has some distinct characteristics that make it a good choice for many applications. In this article we will explore the field of application and the working principle of EGXF251ELL680MK30S.

Field of Application

EGXF251ELL680MK30S aluminum electrolytic capacitors provide excellent performance in various applications such as power supplies, motor drives, audio frequency generators, amplifiers, timers, and lighting. It is suitable for AC or DC power supplies and voltage ranges from 6 to 660V.

The capacitor is a high stability and high ripple current type with a rating of 121μF, 25V, 0.25A. The ESR is 100 mΩ (max) and it is a low leakage type with a leakage current of 0.05CV or 0.13mA (max). This makes the EGXF251ELL680MK30S a good choice for applications that require high stability and low leakage.

The EGXF251ELL680MK30S also features low impedance, low self-inductance, and high operating temperature. The minimum operating temperature is -25 degrees Celsius and the maximum is +105 degrees Celsius. For safety considerations, it has a long life and is certified to withstand an hour at 135 degrees Celsius and humidity up to 85%.

The EGXF251ELL680MK30S is an ideal capacitor for high power circuitry such as motor control, servo control, HVAC systems, and audio frequency circuits. It can be used in applications where long life, low ESR and noise, and a wide temperature range is desired.

Working Principle

The EGXF251ELL680MK30S operates on the principle of electrolytic capacitance. The capacitor is composed of two electrodes, one made of aluminum and the other made of a material that has a greater affinity for electrons. The aluminum is anode and the other material is cathode.

The two electrodes are separated by an electrolyte and the positive ions from the electrolyte are attracted to the negatively charged anode. This creates an electric field that stores energy and serves as a charge and discharge feature. When a voltage is applied to the electrodes, a current is formed and charges the capacitor. When the voltage is removed, the capacitor discharges.

The current stored in the capacitor is determined by its capacitance, which is measured in Farads. The EGXF251ELL680MK30S has a capacitance of 121mF, which is suitable for many applications. The higher the capacitance, the greater the charge and discharge current capacity.

The ESR is also a key component of the EGXF251ELL680MK30S. ESR stands for "Equivalent Series Resistance" and runs in direct opposition to the capacitive current applied. The ESR limits the amount of current that can be drawn from the capacitor, which is why the EGXF251ELL680MK30S has such a low ESR. The lower the ESR, the better the performance of the capacitor.

The EGXF251ELL680MK30S also features a long life and is certified to withstand up to 135 degrees Celsius with no degradation in performance. This is due to its high stability and low leakage current that make it a great choice for applications that require long life and high reliability.

Conclusion

The EGXF251ELL680MK30S aluminum electrolytic capacitor is a highly reliable and stable capacitor that is suitable for high power circuitry. It is characterized by its low leakage current, low ESR, and wide temperature range. Its long life and high temperature resistance make it a great choice for applications that require reliable and long-lasting performance.
