Aluminum electrolytic capacitors belong to a category of capacitors that use an aluminum oxide film as the dielectric medium with one of the two plates of the capacitor being rolled up for increased capacitance and voltage ratings. This roll-up of the plate also allows for a very low ESR (Equivalent Series Resistance). The EEU-HD1C331B is a radial-leaded, screw locking, surface-mounted cylindrical-shaped, non-solid electrolytic aluminum capacitor.

The EEU-HD1C331B has a capacitance range of 10uF to 47uF and a rated voltage range of 6.3V to 100V. The capacitors temperature range is -25/+105 degrees Celsius with a short-time overload pulse current capability of up to 100A. The capacitors maximum package size is 10mm x 15mm, with an insulation resistance of ≥3000MΩ (minute) and dissipation factor of ≤0.25%.

The application fields of the EEU-HD1C331B capacitor are varied, and they can be used in DC/DC converters, TV tuners, wireless handsets, digital cameras, notebook and desktop computers, RF equipment, and audio-visual equipment. They possess a reliable performance even in critical, instantaneous high current application scenarios.

The working principle of aluminum electrolytic capacitors is quite simple. Electrolytic capacitors are constructed of two aluminum foils, rolled and embedded in a liquid or solid electrolyte. As an electric current is passed through the electrolyte, a thin oxide film will form on the surface of the positive electrode foil, thereby creating an electric double-layer capacitance. When a voltage is applied to the capacitors, the electric field will cause the oxide film to grow thicker, providing very high capacitance and long life time.

Although the EEU-HD1C331B is a radial-leaded radial capacitor, which features a plastic case as opposed to the classic cylindrical aluminum case, it still holds true to its aluminum electrolytic capacitor heritage. A unique feature of the EEU-HD1C331B is its screw lock system which ensures a secure connection and protects against any damage the capacitor may encounter owing to any potentially harsh environmental conditions.

In conclusion, it can be seen that the EEU-HD1C331B aluminum electrolytic capacitor has a wide range of applications, a long life time, and a reliable performance even in high current or harsh environmental conditions. The capacitor is easy to use and provides excellent noise-free performance with minimal self-inductance and high level of reliability and consistency.
