• Introduction: Aluminum electrolytic capacitors are very common in the electronics industry and have been used in many applications. This article will discuss the application field and working principle of the 350VXH390MEFC30X35 aluminum electrolytic capacitor.
• Application Field: The 350VXH390MEFC30X35 aluminum electrolytic capacitor is widely used in audio equipment, signal control applications, computer applications, motor control applications, and uninterruptible power supply systems. It is especially useful for noise suppression and AC ripple current applications. It has a capacitance of 39µF and a rated operating temperature of -25°C to +85°C.
• Working Principle:
  • An aluminum electrolytic capacitor is constructed with two aluminum sheets with oxide coats separated by a spacer. In between these two oxide layers is an electrolyte solution which acts as the dielectric material. The outer oxide layer forms a barrier that prevents leakage current from affecting the inner layer of oxide. This inner layer, when polarised, will create an electric field that amplifies the capacitance of the capacitor.
  • When the capacitor is connected in a circuit, electrical current flows through the plate on the bottom of the capacitor. This current will generate a magnetic field that polarizes the inner aluminum oxide layer. The relative permittivity of the aluminum oxide layer increases, which in turn increases the capacitance of the capacitor and allows the device to store and release electrical energy.
  • The capacitor is also able to filter electrical noise in various types of applications. An AC ripple current may be passed through the capacitor and be stored in the dielectric material. When the ripple current passes through the capacitor, it is filtered and the energy is stored in the capacitor. When the energy is removed from the capacitor, it can be used to power devices or simply as a source of energy.
• Conclusion: The 350VXH390MEFC30X35 aluminum electrolytic capacitor is an important component in a variety of applications. Its ability to store and release electrical energy makes it a valuable device in signal control, computer, and motor control applications. Its ability to filter electrical noise also makes it useful for audio and UPS applications. By understanding its application fields and working principles, one can properly utilize this device for its intended purpose.
