SEK010M350ST Application Field and Working Principle

Aluminum electrolytic capacitors are a type of electrolytic capacitor, which consists of an anode, typically aluminum foil, a cathode composed of aluminum oxide, and an organic electrolyte. They are commonly used for decoupling, filtering, timing, and other applications. The SEK010M350ST is an aluminum electrolytic capacitor specifically designed for use in higher temperature and higher voltage applications.

Construction and Features

The SEK010M350ST is a miniature aluminum electrolytic capacitor that features a long life of 2000 to 6000 hours, and a temperature range of -55°C to 105°C. It is constructed with metalized aluminum foil anode, an aluminum oxide dielectric, and a saturated organic electrolyte. The construction enables it to withstand higher voltages than typical aluminum electrolytic capacitors, while maintaining a high capacitance.The SEK010M350ST has a high ripple current capability of up to 4.9Apeak, and offers stable performance up to 105°C. It also features a +15/−20% tolerance.

Applications

The SEK010M350ST is designed for use in higher temperature and higher voltage applications. It is commonly used in automotive and industrial applications, such as electric vehicles, air conditioners, solar energy systems, and high temperature energy storage systems. The SEK010M350ST is also suitable for use in power supplies, and for signal and linear de-coupling applications.

Working Principle

The SEK010M350ST works on the same principle as other aluminum electrolytic capacitors. When voltage is applied, the electrons in the anode will attract ions to the surface of the oxide dielectric, creating an electric field. The electric field will create opposite charges on either side of the dielectric, which will in turn create a capacitance.The SEK010M350ST\'s high performance comes from its high temperature range and highripple current capability, which enable it to provide stable performance and a long life in high temperature applications, without having to sacrifice capacitance for higher voltage ratings. In conclusion, the SEK010M350ST is a highly versatile aluminum electrolytic capacitor designed for use in higher temperature and higher voltage applications. It provides a long life and stable performance, and is suitable for a wide range of automotive and industrial applications.
