Aluminum electrolytic capacitors are a type of capacitors which has gained widespread use in recent years due to their large capacitance, low cost, small form factor, robustness and low self-discharge rate. The basic principle of such a capacitor is based on the electrochemical properties of aluminum. In this type of capacitor, two closely spaced aluminum foils act as the electrodes, while a thin strip of electrolytic paper separates them and acts as the dielectric. The aluminum foils are rolled together tightly and then encased in a metal can, with the electrolyte filling in the space around the two foils.

The PSU85015 is a type of aluminum electrolytic capacitor. This type of capacitor is designed for use in power supplies and DC to AC power converters, offering long life and a lower equivalent series resistance (ESR). Additionally, it has a low-profile design, which allows it to fit in tight spaces. It consists of two rolled-up aluminum foils, with an electrolytic solvent in between, around which a metal cylinder is wrapped. The metal can acts as a barrier, protecting the fragile di-electric media from environmental influences.

The capacitance of the PSU85015 is relatively low, ranging from 0.7uf to 1uf. This is because the capacitance of an aluminum electrolytic capacitor is determined by the thickness of the electrolyte between the two foils. The lower the capacitance, the thicker the electrolyte. The PSU85015 also has a low ESR of 80mOhm and a high insulation resistance (IR), providing low electrical leakage and a long working life.

When it comes to application fields, the PSU85015 is primarily used in power supplies and DC-to-AC converters, offering long life and low ESR. Additionally, it is suitable for use in renewable energy applications, such as solar panels and wind turbines, thanks to its high insulation resistance. It is also often used for filtering and smoothing signals in various electronic devices.

In terms of working principles, the PSU85015 operates the same as any other aluminum electrolytic capacitor. The aluminum foils act as electrodes, and the electrolytic solvent acts as the dielectric medium. When a voltage is applied, the electrolyte allows charges to migrate across the area between the foils, resulting in the formation of an electric field. This electric field is what stores the capacitor\'s energy. As the capacitor charges and discharges, the electric field weakens and strengthens, resulting in the charges migrating back and forth between the foils.

The PSU85015 is a reliable and cost-effective option for powering various electronic devices and renewable energy applications. Its low capacitance, low ESR, and high insulation resistance make it ideal for use in these applications. Furthermore, its small form factor makes it easy to integrate into existing systems.
