Aluminum electrolytic capacitors are a type of capacitor that uses aluminum electrodes with an oxide layer acting as a dielectric. They are used for filtering, buffering, decoupling, energy storage, power factor correction, and high-current applications in a variety of electronic systems and devices. The EEU-FR1V182B is an aluminum electrolytic capacitor that can be used in various applications, such as switch mode power supplies, DC-DC converters, and inverters, among others. This article will discuss the application field and working principle of the EEU-FR1V182B.

The EEU-FR1V182B is a radial-leaded aluminum electrolytic capacitor that is available in a wide assortment of capacitance values, ranging from 8µF to 680µF. It has a rated voltage of 16V and a rated ripple current of 140mA at 105°C. The device has a 70°C operation rating and a maximum capacitance tolerance of ±20%. The device has an operating temperature range of -25°C to +85°C, with a 5,000-hour life expectancy.

The EEU-FR1V182B can be used in a variety of applications, such as high-frequency switching power supplies, DC-DC converters, inverters, and regulated power supplies. It can also be used in AC adaptors for portable devices, telecommunciations equipment, auto-electronic control systems, industrial equipment, and power conditioning circuits. The device can handle high ripple currents at low ESRs, making it suitable for high-frequency switching power supplies. The device also has excellent electrical characteristics and a good temperature coefficient.

The working principle of the EEU-FR1V182B ambient-temperature type aluminum electrolytic capacitor is as follows. The device consists of a cylindrical aluminum body that acts as an anode and a layer of anodic oxide on the cathode that acts as a dielectric. Inside the device is an organic electrolyte, which electrolyzes the anode, forming a thin layer of aluminum hydrate on the surface of the anode. This layer provides a dielectric layer for the capacitor, which allows for the flow of energy. When voltage is applied to the device, a capacitance is formed.

The EEU-FR1V182B has a self-healing effect, which means that when the device is connected to a voltage source, the leakage current builds up until it reaches a critical level, at which point the dielectric layer created by the oxidation of the anode will be healed. This healing process takes place independently from the application of voltage or current. This feature makes the device suitable for use in high-voltage and high-frequency circuits, as it is able to withstand extreme temperatures and provides excellent electrical characteristics.

In conclusion, the EEU-FR1V182B is a radial-leaded aluminum electrolytic capacitor that is available in various capacitance values. It can be used in a variety of applications, such as high-frequency switching power supplies, DC-DC converters, and inverters. The device has excellent electrical characteristics, excellent temperature coefficient, and self-healing effect. Understanding the application field and working principle of the EEU-FR1V182B can help engineers determine the best capacitor for their specific design needs.
