Aluminum Electrolytic Capacitors and the SEK2R2M160ST

Aluminum electrolytic capacitors are two-terminal, non-polarized components consisting of an anode made of an aluminum foil and a paper spacer soaked in electrolyte. It is used in many circuit applications such as electronic filters, amplifiers, power supplies, motor circuits, and instrument circuits. Among the many types of aluminum electroyltic capacitors, the SEK2R2M160ST is one of the most important.

Application Fields of SEK2R2M160ST:

The SEK2R2M160ST is a series of aluminum electrolytic capacitors developed specially for the power supplies of digital devices such as computers and printers. It has a wide voltage range of 6.3V, 100V, and 200V, and a capacitance range of 0.47uF to 50uF. It also features low equivalent series resistance of 0.5Ω, making it ideal for powering digital devices.

Working Principle:

The SEK2R2M160ST capacitor works in a way similar to other electrolytic capacitors. It consists of multiple layers of an anode of aluminum foil and a cathode of special paper soaked in a liquid electrolyte. The electrolyte provides the necessary ions for conduction between the anode and cathode. When an AC voltage is applied to the capacitor, the electrical current creates an electrostatic field between the two layers, which acts as a charge storage device. The stored energy is discharged when the applied voltage reverses.

Advantages of SEK2R2M160ST:

The SEK2R2M160ST is a popular choice for the design of power supply circuits because of its unique design and performance. It has the following advantages:

• High withstanding voltage of up to 200V
