Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electronic device composed of two conducting electrodes, separated by a thin dielectric layer of aluminum oxide. This type of capacitor is widely used in various applications, such as power supply decoupling and signal smoothing.

The UKA1C471MPD is a type of aluminum electrolytic capacitor, and it combines features of both snap-in and snap-in variant capacitors. It has a snap-in base that can be mounted on the circuit board, while its holding bore can withstand up to 16 mm of lateral vibration. This makes it ideal for use in mobile and portable devices, where prolonged vibration and frequent operation-related movement can be expected.

In terms of construction, the UKA1C471MPD is a high-temp type aluminum electrolytic capacitor. It consists of two silver-tinned copper plates, coated with a layer of aluminum oxide. To increase the capacitance and ripple current levels of this device, two additional layers of conductive aluminum foil are inserted in between the plates, forming a large capacitor structure. In this type of device, the small insulating gap between the plates is filled with an electrolyte, usually a mixture of borax and aluminum.

The working principle of an aluminum electrolytic capacitor is based on the law of capacitance. When an external electric field is applied across the terminals of the device, opposite charges are induced on its plates. This creates an electrical field between the plates, known as the electrostatic field. This field tends to separate the negative and positive charges, thus resulting in a separation of energy levels. As a result, a voltage is produced across the plates, and a corresponding electric current is established, which can be used for various applications.

Due to its high temperature operating characteristics, the UKA1C471MPD can be used in a variety of applications. Firstly, it is ideal for use as a power supply decoupling capacitor, due to its ability to reduce voltage spikes and prevent excessive ripple current. Secondly, it can be used as a signal smoothing capacitor, which helps reduce electrical noise, eliminate harmonics and improve signal fidelity. Additionally, the UKA1C471MPD has been used in automobile and industrial applications, such as engine control units, power meters, and power-factor correction.

Finally, due to its high capacitance and long life expectancy, the UKA1C471MPD is also suitable for use as an input or output capacitance in analog circuits, to enhance the dynamic range and improve the reliability of the signal.

In conclusion, the UKA1C471MPD is an excellent aluminum electrolytic capacitor, possessing high temperature resistance, high capacitance values and long life expectancy. Thus, it provides excellent performance in a variety of applications, ranging from power and signal smoothing, to analog signal enhancement.
