Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also known as an "electrolytic capacitor", is a polarized capacitor mainly used in electronic circuits. It has an electrolyte which acts as the dielectric, using an aluminum oxide layer as a semiconductor layer that blocks the flow of electricity when it is uncharged. Its model 25MH76R8MEFC4X7 is a kind of multi-section capacitor with a special combination.

Application Field of 25MH76R8MEFC4X7

The 25MH76R8MEFC4X7 is widely used in various circuit applications. Due to its unparalleled combination and compact size, it is widely used in high frequency AC circuits, impedance resonance circuits, pulse conversion circuits, adjustable speed control circuits, high frequency power cords and choke coils. It is also used in frequency modulation equipment, monitoring equipment, communication equipment, radio, television and other electronic instruments.

Working Principle of 25MH76R8MEFC4X7

The 25MH76R8MEFC4X7 consists of two electrodes: positive and negative. The positive electrodes are made of aluminum foil covered with an oxide layer while the negative electrodes are made of a metal with a low potential for corrosion, such as manganese or stainless steel. The electrolytic fluid (usually aqueous solution of ethylene glycol or sodium bicarbonate plus a conducting salt) acts as an insulator between the two electrodes. The electrolytic fluid conducts current only when there is a potential difference between the two electrodes. This potential difference is created when an electric field is applied to the power leads. When the electric field increases, electrons start moving across the electrolyte from the negative electrode towards the positive electrode, a current is created.

The current that’s generated in the electrode creates an ion flux, which causes the negative ions in the electrolytic fluid to be attracted to the positively charged electrodes and positive ions to be attracted to the negatively charged electrodes. As the ions move around, the electric potential decreases, creating a potential difference between the two electrodes until an equilibrium is reached between the force of the current and the forces of the opposite charges.

This process creates a charge storage effect that allows the 25MH76R8MEFC4X7 to store a certain charge for a certain period of time, which is necessary for its use in different types of electronic circuits and devices. The ability of the capacitor to be correspondingly charged and discharged makes it an ideal choice for applications such as frequency modulation, voltage regulation, phase modulation, frequency filtering, and power factor correction.
