Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most widely used type of capacitor. Also known as electrolytic or polarized capacitors, they are made up of an electrolyte – usually water or oil – and several flat plates of aluminum foil, separated by insulating paper. They are typically used in a wide range of applications, from filtering and decoupling to storage and power supply conditioning.

The 630D476M200FH2A capacitor is a popular electrolytic capacitor. It is a Radial Lead Electrolytic Capacitor with a 47μF capacitance and 200V DC nominal voltage. It has a current leakage of 3mA, a dielectric absorption of 7-12 hours, a surge voltage of 500V and an endurance rating of 5,000 hours at 120℃. It is a non-polar capacitor, meaning it has no specific polarity and can be mounted in either direction.

Application Field of 630D476M200FH2A

The 630D476M200FH2A capacitor is typically used for power supply filtering, decoupling and bypass circuits. It is also suitable for short-time and low-frequency pulse circuits. It is ideal for applications such as switched-mode power supply filtering, automotive electronics, factory automation systems, medical instruments, communications equipment and other consumer electronics.

Working Principle of 630D476M200FH2A

Aluminum electrolytic capacitors work by using a chemical reaction to produce electrical energy. The anode and cathode consist of aluminum and electrolyte plates, respectively. Once current is applied, a thin layer of oxide forms on the aluminum plate to insulate it from the electrolyte. This layer prevents the current from leaking across the plates, and it also acts as a charge storage device.

When the applied voltage is of the opposite polarity of the charge stored in the capacitor, the oxide layer begins to discharge. This causes current to flow from the anode to the cathode, allowing the capacitor to store and discharge energy. This energy is used to filter out unwanted signals, decouple power supplies, or provide additional current in short bursts when needed. As a result, aluminum electrolytic capacitors such as the 630D476M200FH2A are indispensable components in modern electronics.
