Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized electrochemical components with a wide range of applications in electronics. They are typically used for filtering, storing, and smoothing electrical signals, sometimes in power supplies and medical instrumentation. Their use in electronic circuits has increased due to the demand for higher power density and increased stability.

UKL1C471KPD

The UKL1C471KPD is an aluminum electrolytic capacitor designed for switching power supplies. It has a long life expectancy of up to 2000 hours at full rated temperature and has no risk of emergency failure. It is also resistant to acids, alkalis, water, and other common elements.

Application Field

The UKL1C471KPD is suitable for use in a variety of applications, including general-purpose and medium power applications, as well as low impedance power supplies, alternative power supplies, H-bridges, DC-DC converters, motor drives, and audio amplifiers. It is also suitable for high frequency, high current, and high-power applications such as those found in solar energy systems, automotive electronics, and industrial automation.

Working Principle

An aluminum electrolytic capacitor is composed of two semi-permeable foils that are wound around an electrolyte material and separated from each other by a layer of non-conductive material called a dielectric. The foils act as the two electrical plates of the capacitor, and when a voltage is applied, an electric current is generated and stored in the capacitor. The capacitor will become charged when the electric current is applied and discharged when the electric current stops. When an aluminum electrolytic capacitor is connected in a circuit, the current from the power source will travel through the circuit and into the capacitor, generating and storing electrical energy. The capacitor then releases the energy when the current stops. This is the basic operating principle of an aluminum electrolytic capacitor.The advantage of an aluminum electrolytic capacitor is that its charge/discharge time is very short, potentially reaching as low as 1000th a second compared to other capacitors. This makes them suitable for use in high-speed applications such as motor drives, power supplies and audio amplifiers, where quick charging and discharging of the capacitor are necessary.

Conclusion

The UKL1C471KPD is an aluminum electrolytic capacitor designed for switching power supplies. It has a long life expectancy and is resistant to acids, alkalis, water, and other elements. It is suitable for a range of applications, including low impedance power supplies, alternative power supplies, H-bridges, DC-DC converters, motor drives, and audio amplifiers. The capacitor operates by accumulating and releasing electrical energy through its two foils when a voltage is applied and when it is stopped. This makes it suitable for higher frequency and higher power applications.
