Aluminum electrolytic capacitors are electrical components featuring largely increased capacity per unit volume in comparison to other capacitor types. This is caused by the phenomenon of double electric layer formation on the dielectric anode surface.

The UKA0J470MDD1TD is an aluminum electrolytic capacitor designed for use in automotive, telecommunication devices and consumer electronics such as TVs, radios, LED lighting and other appliances. It offers an improved performance and reliable operation over the wide temperature range of -40 to +105°C. It also features a low impedance, long operating life and high ripple current capability.

The working principle of aluminum electrolytic capacitors is based on the properties of a dielectric anode and an electrolytic liquid. When a voltage is applied to the capacitor, an oxide layer is formed on the anode. This oxide layer provides insulation between the anode and the electrolyte. As the current flows through the electrolyte, electrons in the electrolyte are attracted to the anode, creating two layers of charge – a negative charge layer near the anode and a positive charge layer near the electrolyte. This creates a potential difference between the anode and the electrolyte and a charge across the capacitor.

The UKA0J470MDD1TD also has a long-life performance due to its high capacity. The design of the capacitor allows for high ripple currents, which is advantageous for applications that experience large load current fluctuations such as Class D audio amplifiers. The capacitor is also designed with a low ESR, enabling it to be used in high- frequency applications, such as switch mode power supplies and DC-DC converters.

The UKA0J470MDD1TD Furthermore features a low self-discharge rate and wide temperature range, making it suitable for temperature-sensitive applications. In addition, the capacitor is lead-free, and RoHS and REACH compliant, making it a safer, more environmentally friendly choice.

In conclusion, the UKA0J470MDD1TD aluminum electrolytic capacitor is a reliable, low-cost solution for use in a wide range of electronics applications, such as automotive, telecommunication devices and consumer electronics. It is designed to provide a high performance, long operating life and high ripple current capability. Its low self-discharge rate and wide temperature range make it suitable for temperature-sensitive applications as well. Moreover, it is lead-free, RoHS compliant and REACH compliant, making it a safer, more environmentally friendly choice.
