Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components used in many types of electronics. They are used in High End Audio and Video applications, in automotive and aerospace systems, and medical equipment. Aluminium electrolytic capacitors are widely used due to their relatively low cost, high Q (high capacitance per unit volume) and low impedance. They are constructed from a sheet of aluminium foil which has a thin oxide layer on the surface. This layer acts as the dielectric and allows the capacitor to store electrical charge.

The 158LBA200M2EG aluminum electrolytic capacitor is a surface mount device. It has an extended temperature range of -40°C to +105°C, a capacitance of 200μF and a working voltage of 100Vdc. The main features of the 158LBA200M2EG are: small size, low leakage current, high reliability long life, good temperature stability and long shelf life.

Application Fields

The 158LBA200M2EG aluminum electrolytic capacitor is used in a variety of applications where high reliability and long life are required. These include:

• Automotive and aerospace systems
• High End Audio and Video systems
• Medical equipment
• Industrial controls
• Power supplies
• Communication systems
• Marine equipment

Working Principle

Aluminum electrolytic capacitors operate on the principle of electrolytic separation of the aluminum foil and the conducting liquid acting as the electrolyte. When a voltage is applied to the capacitor, an electric field is generated across the thin oxide layer on the surface of the aluminum foil. This electric field causes a separation of charge on each side of the oxide layer. The charges on each side attract each other and create a capacitance or “stored energy” between the two metal discs. This capacitance is determined by the area of the metal discs, the type of dielectric material, the thickness of the dielectric material, and the voltage applied.

The 158LBA200M2EG aluminum electrolytic capacitor has a long life which is determined by how much energy can be stored within the capacitor without breaking down due to the heat generated by the electric field. Heat is generated due to the conversion of electrical energy into thermal energy when a current passes through the capacitor. As long as the energy is not exceeded, the capacitor will last a long time. The 158LBA200M2EG capacitor is designed to be used for up to 105°C operating temperature and has a shelf life of 5 years at 25°C.

Conclusion

The 158LBA200M2EG aluminum electrolytic capacitor is a small, reliable, and long-lasting component used in many types of electronics. It has an extended temperature range of -40°C to +105°C, a capacitance of 200μF, and a working voltage of 100Vdc. It is used in automotive and aerospace systems, high end audio and video applications, medical equipment, industrial controls, power supplies, communications systems, and marine equipment. The capacitor operates on the principle of electrolytic separation of the aluminum foil and the conducting liquid acting as the electrolyte, which creates a capacitance between the two metal discs. Its long life and high reliability make it an ideal choice for many applications.
