Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that is commonly used in a wide variety of electrical applications. These capacitors are made from two sheets of aluminum foil rolled together and sandwiched between two layers of electrolytic paper. The two layers of foil are then separated by electrolyte and held tight by an electrolytic gel. The electrolytic paper forms a dielectric layer that provides an insulation between the two layers of foil. The combination of the aluminum and the electrolytic paper create a capacitor that has excellent qualities such as low ESR, high capacitance and a wide range of working temperature range.

SMG25VB103M22DLL is an example of an aluminum electrolytic capacitor. It is a radial leaded type that has a rated voltage of 50VDC and a rated capacitance of 10,000μF. This capacitor has a lead spacing of 22mm and a tolerance of ±20%. It is a temperature compensation type capacitor with a long life expectancy and high ripple current ratings. It is a popular choice for high-frequency switching applications due to its low ESR and high capacitance.

Application Field and Working Principle

Aluminum electrolytic capacitors are commonly used in power supplies, amplifiers, computers, and other types of electronic equipment. Their high capacitance and low voltage ratings make them an ideal choice for these types of applications. In power supplies, they are often used to stabilize the output voltage and current. In amplifiers, they are used as the main storage capacitor. In computers, they are used for various filtering and timing applications, including voltage decoupling, phase-locked loop (PLL) timing, and frequency modulation (FM) applications. In addition to these applications, they are also used for motor start and run applications, as well as for filtering the power supply input to reduce noise from the power supply.

The working principle of an aluminum electrolytic capacitor is quite simple. When a voltage is applied to the two plates of the capacitor, the two layers of aluminum foil are attracted to each other and charge up. The charge on one side is then conducted to the other side by the electrolyte. This is how the capacitor stores the charge and creates its capacitance. The higher the voltage of the capacitor, the bigger the capacitance. The capacitance can be changed by changing the number of layers of aluminum and electrolyte or by changing the thickness of the electrolyte.

The main advantages of aluminum electrolytic capacitors include their high capacitance, low ESR, long life expectancy, and excellent temperature compensation. Their low ESR and high capacitance make them ideal for applications such as power supplies and amplifiers. In addition, their long life expectancy and temperature compensation make them suitable for use in a wide range of temperatures.

In conclusion, aluminum electrolytic capacitors are a type of capacitor that are commonly used in a wide variety of electrical applications. SMG25VB103M22DLL is an example of an aluminum electrolytic capacitor, with a rated voltage of 50VDC and a rated capacitance of 10,000μF. The working principle of an aluminum electrolytic capacitor is quite simple, and the main advantages include their high capacitance, low ESR, long life expectancy, and excellent temperature compensation. These qualities make aluminum electrolytic capacitors an ideal choice for a wide variety of applications.
