Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors and are commonly used for applications that require high capacitance, such as power-supply filtering, AC receptacle power delivery and coupling, as well as bypass circuits in audio and communication equipment, etc. The UKZ2A100MPM aluminum electrolytic capacitor is one such product produced by United Chemi-Con, a renowned manufacturer of electrolytic capacitors.

UKZ2A100MPM application field

The UKZ2A100MPM is the higher capacitance version of the UKZ2A10MPM, in which the larger application range allows it to be widely used, including high-frequency voltage dividers, DC-DC converter smoothing, power filtering, and high-dropout regulator circuits.

In a voltage-dividing circuit, the UKZ2A100MPM is mainly used for voltage smoothening, noise reduction, and distortion correction. It can also be used to filter the output current of the linear power supply and the switching power supply, and can be used to filter noise to reduce ripple. In DC-DC converter smoothing and filtering circuits, the UKZ2A100MPM smoothens the output of the DC-DC converter and filters the output current to reduce ripple.

Moreover, this capacitor is also widely used in the circuit-protection system as it responds fast and has small leakage current. It integrate protective capacitance, surge-proof and leakage-resistant capacity into a single unit. It is also used to improve electromagnetic compatibility. In addition, in battery-charging circuits, the capacitor absorbs the ripple current produced by the load and battery charging and discharging.

UKZ2A100MPM principles of working

The UKZ2A100MPM belongs to the category of aluminum electrolytic capacitors, and it is able to accomplish the charge-discharge process due to its working principles. The working principles of an aluminum electrolytic capacitor are based on a voltage differential between two conducting plates in an electrolyte solution. By this method, a current flowing through the solution creates two layers of charge, resulting in a static electric field between the two conducting plates.

The UKZ2A100MPM combines two aluminium foils, each bearing a thin oxide layer, which are separated from each other by a thin dielectric film and impregnated in a nonvolatile electrolyte. The electrolyte is highly conductive, so it completely fills the available space between the plates and ensures that the voltage applied to the capacitor is distributed evenly over the entire surface of the plate.

When an electric current is applied to the capacitor, a charge accumulates on the plates, known as the capacitive charge. The capacitive charge stored in the capacitor is proportional to the magnitude of the electric field strength produced. The capacitive charge stored in the capacitor continues to accumulate so long as a voltage differential is applied to the electrodes, and the electric field continues to flow through the semiconductor.

The UKZ2A100MPM has excellent frequency characteristics and provides low distortion. It is designed with low equivalent series resistance and equivalent series inductance for superior stability and superior transient response. It also provides excellent temperature compensation and improved temperature coefficient stability. Other notable features of the UKZ2A100MPM include low DC leakage, low ESR and high ripple current.

Conclusion

The UKZ2A100MPM aluminum electrolytic capacitor is an ideal solution for applications that require high capacitance. This capacitor is capable of providing low distortion, low equivalent series resistance and equivalent series inductance, and excellent temperature compensation, making it suitable for a wide range of applications.
