Aluminum electrolytic capacitors are widely used in power supplies, radio communication systems, electronic instruments and many other fields for peak load current supply, frequency adjustment, energy storage, circuit decoupling, energy filtering and noise suppression. The most common type of aluminum electrolytic capacitor is the axial-lead type, which is most often found on PCBs. The EET-HC2S181HA is a radial lead aluminum electrolytic capacitor that has both the advantage of high capacitance value and proven reliability.

The EET-HC2S181HA aluminum electrolytic capacitor is a miniaturized radial lead device in a very small package with a maximum height of only 4.5 millimeters which makes it ideal for applications where space is limited. The capacitor has a rated voltage of 25 volts, a capacitance of 6800 µF and an operating temperature range of -55°C to +85°C and a lifetime of 1000 hours at 85°C.

The EET-HC2S181HA is a multi-purpose capacitor, suitable for use in a variety of applications. In the consumer electronics industry, it is often used in the power supplies of portable devices such as laptop computers, cell phones, and tablets. It can also be used in a variety of industrial applications such as motor drives, AC/DC power supplies, power modules, and UPS systems. The capacitor is also suitable for use in automotive and aerospace systems due to its high temperature range, long life expectancy, and reliability.

The working principle of the EET-HC2S181HA aluminum electrolytic capacitor is based on the principle of electrolyual flow. It consists of a steel end plate and a non-conductive aluminum foil roll. In between these two components, a special electrolyte (often a mixture of ammonium chloride electrolyte) is introduced and foaming of water molecules takes place. This resultant electrolyte provides a strong electrical conduction layer between the aluminum and steel layers. While charging, electrons from the positive terminal of the supply move opposite to the current flow at the negative terminal, and the aluminum is oxidized at the negative terminal resulting in the generation of positive ions. Simultaneously, the water molecules try to rearrange itself to balance the charge and this provokes an electrical flow.

The EET-HC2S181HA aluminum electrolytic capacitor provides excellent performance with its high capacitance and desirable leakage current characteristics. It is reliable, has a longer lifetime and is available in a size that allows for design optimization and minimal size requirements for the PCB. The capacitor is low cost, easy to use, and most suitable for use in electronic circuits that require robust performance.
