UVR1HR47MDD

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are an important category of electrolytic capacitors. They are very versatile and are used in many applications, including audio equipment, power supplies, DC/DC converters, switching power supplies, and motor drives. These capacitors use aluminum foils treated with special anodic oxidation processes as their electrodes, and they are filled with a liquid or semi-liquid electrolyte as their dielectric. Because of their excellent electrical properties, such as high capacitance, low internal resistance, and low or no leakage current, they are used in a wide range of applications.

UVR1HR47MDD application field and working principle

The UVR1HR47MDD is a radial-leaded aluminium electrolytic capacitor manufactured by Rubycon. It is an electrolytic capacitor which has a large capacitance range from 22µF to 1000µF and a voltage rating range from 6.3V up to 100V. The small size and lightweight make UVR1HR47MDD suitable for multiple applications.The UVR1HR47MDD has two aluminum foils as electrodes. It is filled with an electrolyte and sealed in a metalized polypropylene film. The polypropylene film acts as the dielectric and provides the required electrical insulation. The electrodes are connected to the capacitor terminals, which are made of nickel-plated phosphate copper. The current flows between the two electrodes when an electric field is applied to the capacitor. The electric field induces a movement of the electrons, which results in an accumulation of electric charge on the capacitor plates.

This accumulation of electric charge gives rise to potential difference between the two electrodes which is known as the electrolytic capacitor’s capacitance. The capacitance depends on the size of the capacitor’s plates, the dielectric material between the plates, the distance between the plates, and the voltage applied to the capacitor. The UVR1HR47MDD’s capacitance range is calculated using its standard formula.

The UVR1HR47MDD has various applications such as industrial or commercial circuits, controller boards, energy storage systems, converters and rectifiers, filtering, and power distribution. Its small size and light weight make it an ideal choice for applications where space and weight are critical factors. UVR1HR47MDD is also a popular choice in audio and power supply circuits because of its excellent characteristics such as ripple current resistance, temperature stability, and reliability.Its temperature range of -55°C to +105°C and its rated voltage of 6.3V to 100V make UVR1HR47MDD suitable for a wide range of applications. It also has a self-healing mechanism which means that it can withstand short circuits and high-voltage spikes without being damaged. This makes UVR1HR47MDD a popular choice for circuit protection.

In conclusion, UVR1HR47MDD is an ideal choice for applications where a large capacitance, low voltage, and temperature stability are required. UVR1HR47MDD is suitable for both commercial and industrial applications due to its small size, light weight, and excellent characteristics. Its self-healing mechanism makes it suitable for circuit protection, and its temperature stability makes it an ideal choice for audio, power supply, and controller board applications.
