Aluminum electrolytic capacitors (AECs) are a type of capacitors that has recently become increasingly common in various industries and applications. AECs offer several advantages over other types of capacitors, such as high energy density, low leakage current, and long life. The 475CKE400MFH AECs provide these advantages, along with excellent reliability and high performance, making them a good choice for many applications.

Application Field of 475CKE400MFH AECs

The 475CKE400MFH AECs are a type of polarized aluminum electrolytic capacitor designed specifically for high-temperature applications. They have a wide range of applications, including in power supplies, lighting, automotive and aerospace systems, defense systems, and renewable energy systems. The high-temperature range allows these capacitors to be used in applications where temperatures can reach up to 105°C. This makes them ideal for use in a range of high-temperature applications, such as LED lighting, switching power supplies, or automotive electronic control units.

The 475CKE400MFH AECs also have a wide voltage range and are available in both surface-mount and through-hole packages. This allows them to be used in a variety of applications with different power requirements. For example, they can be used in automotive systems where the voltage range is typically between 6 and 30 V, or in switching power supplies where the voltage range can be significantly higher.

Working Principle of 475CKE400MFH AECs

The working principle of the 475CKE400MFH AECs is based on the use of an aluminum oxide layer that is a few angstroms thick. The layer of aluminum oxide serves as a dielectric between two metal electrodes. When a voltage is applied across the electrodes, an electric field is generated that causes a current flow between them. This current is what is known as the ‘capacitance’ of the capacitor.

The dielectric strength of a capacitor is determined by the thickness and quality of the dielectric layer. The thicker the layer, the higher the dielectric strength. The 475CKE400MFH AECs have an oxide layer thickness of only 0.1 microns. This makes them very efficient and allows them to achieve very high capacitance values in small packages.

The 475CKE400MFH AECs also have a long life expectancy. This is due to the fact that the aluminum oxide layer is very stable and does not degrade with time. The capacitors are also resistant to vibrations and shocks, which helps to ensure their long operational life.

Overall, the 475CKE400MFH AECs are a reliable and efficient choice for many high-temperature applications. Their wide voltage range and excellent reliability makes them an ideal choice for a variety of different applications.
