Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are an essential component in switching power supplies, audio equipment, and many other consumer electronic products and industrial equipment. The EDH107M6R3A9GAA Aluminum Electrolytic Capacitor is a widely used device with a range of applications.

Application Field

Aluminum electrolytic capacitors are primarily used in high-frequency switching converters, such as DC to DC converters. These converters require a large storage of energy before releasing it to the load. The capacitors used in these applications must be able to perform at a high frequency, low impedance, and high ripple currents, which are essential for the conversion, as well as preventing power supply noise which could adversely affect the circuit. Additionally, aluminum electrolytic capacitors are used in filtering circuits due to their high capacity and relatively low cost, as well as in audio and video circuits, automotive systems, and instrumentation. The EDH107M6R3A9GAA aluminum electrolytic capacitor was designed specifically for use in these types of applications.

Working Principle

Aluminum electrolytic capacitors store electrical energy using the principle of electrochemical double layer capacitance. When an electric field is applied between two layers of the device, ions from both ionic liquids and ions from the electrode material are attracted to the electric field, forming a double-layered charge on the surface of the electrodes. This double-layered charge stores electric energy. The EDH107M6R3A9GAA has an anode consisting of rolled aluminum foil, and each layer of electrolyte is separated by a sheer membrane. This membrane prevents the two ionic layers from reacting, allowing for a high capacitance. The EDH107M6R3A9GAA also features a crimped and sealed cap for additional leakage protection.

Environmental Considerations

Aluminum electrolytic capacitors are typically made of ceramic, aluminum, and organic materials. The EDH107M6R3A9GAA is made using a halogen-free epoxy resin, which is more environmentally-friendly than traditional resins. Additionally, this capacitor has a long lifetime of 5000 hours (at 105°C). The EDH107M6R3A9GAA also features a low self-discharge and an excellent resistance to mechanical shock and vibration, making it highly reliable and reliable in even the most demanding applications.

Conclusion

The EDH107M6R3A9GAA aluminum electrolytic capacitor is an essential component used in numerous applications, such as switching power supplies, audio equipment, and DC to DC converters. This device is designed specifically to meet the needs of these applications, featuring an anode made of rolled aluminum foil and a halogen-free epoxy resin for environmental friendliness. Additionally, its long lifespan and excellent resistance to mechanical and environmental degradation make it reliable in even the most demanding applications.
