Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in power supplies, instrumentation, communications equipment, consumer electronics, automotive electronics and other electronic products. An SXR331M016ST aluminum electrolytic capacitor provides reliable capacitance for power supply delivery in these applications.

Overview of SXR331M016ST Capacitor

SXR331M016ST is a high-reliability, high-temperature aluminum electrolytic capacitor. It has a max. working voltage of 16V and is rated for a capacitance of 330 μF. This aluminum electrolytic capacitor has an operating temperature range of -40°C to +105°C and features a long-term reliability of more than 2000 hours. According to the requirements of the application environment, SXR331M016ST is suitable for reflow soldering during installation.

Application Field and Working Principle of SXR331M016ST

SXR331M016ST aluminum electrolytic capacitors are mainly used in electrical and electronic products, such as power supplies, relay protection, DC/DC converters, instrumentation, consumer electronics, automotive electronics, switching power converters and other markets. Due to its excellent temperature characteristics and long-term reliability, SXR331M016ST aluminum electrolytic capacitors are also widely used in severe environment.

The working principle of aluminum electrolytic capacitor is based on the physical phenomenon that a thin metal layer on the surface of an oxide film acts as a dielectric. After the metal has been anodized, the molecular structure of the oxide film layer contains a large number of oxides, thereby forming a thickness of several to thousands of angstroms high dielectric constant. This dielectric of the oxide film is between the two thin metal layers, which form a dead slot. Due to the capacitance of the oxide film, an electric charge is generated.

For SXR331M016ST aluminum electrolytic capacitors, two pieces of aluminum foil are used as anode and cathode respectively. When voltage is applied to the two poles of the capacitor, an electric charge is generated. The surface of the anode is treated by anodizing technology, forming a thin film, which is used as the dielectric. The dielectric is then impregnated with an electrolyte with a certain conductivity to complete the capacitance formed by the polarized electrolyte on the aluminum foil. This is how SXR331M016ST aluminum electrolytic capacitors works.
