Aluminum electrolytic capacitors are passive components responsible for storing energy, and they are foundational building blocks in all kinds of analog, digital and power electronics circuits. The EEU-FS1A182B is an aluminum electrolytic capacitor that has been designed to be ideal for general electronics applications. This article will detail the application field and working principle of the EEU-FS1A182B.

Application Field

The EEU-FS1A182B capacitor is great for power line filtering in power supplies and DC-DC converters, which is possible due to its generous ripple current ratings. This capacitor is also useful for controlling power supply output ripple voltage, especially when utilized with ceramic chip capacitors in series. Moreover, these capacitors are perfect for energy storage, de-bouncing, freewheeling, snubbing and pulse applications. And unlike conventional electrolytic capacitors, the EEU-FS1A182B variants have impressive operation temperature ranges and self-healing capabilities.

Working Principle

The hardened anode EEU-FS1A182B capacitors are composed of two electrodes and an electrolyte. The two electrodes are constructed from aluminum foil strips, which increase the surface area and enable the capacitor to store more energy. The electrolyte is a mixture of components including water and sulfuric acid, and this mixture helps to create a conductive pathway between the two aluminum foil parts. When electric current passes through the electrolyte, it produces an anodic reaction causing the electricity to be stored and temporarily held at the electrolyte. The anodic reaction allows the electrons to move back and forth producing electrostatic field in the capacitor.

The EEU-FS1A182B capacitors offer several advantages over other capacitors, starting with their low equivalent series resistance (ESR) and significantly lower leakage current. In addition, these capacitors have excellent heat resistance and high ripple current capability, making them ideal for high-definition AV and automotive audio power line applications. They also have much lower capacitance variation over a wide temperature range and offer better capacitance retention over their lifetime.

EEU-FS1A182B aluminum electrolytic capacitors are available in a variety of sizes and voltage ratings, allowing their usage in a variety of applications. They are highly reliable under normal operating and environmental conditions and feature a long life expectancy. Manufactured with advanced designs and processes, the EEU-FS1A182B aluminum electrolytic capacitors offer superior performance and efficiency.
