Aluminum electrolytic capacitors are one of the most widely used types of capacitors because they offer advantages over paper capacitors, ceramic capacitors and tantalum capacitors. This type of capacitor is characterized by its extremely high capacitance values, very high dielectric strength, low ESR and very high energy density.

The United Chemicals UPW1V471MPD aluminum electrolytic capacitor is no exception from the average aluminum capacitor in terms of reliability, performance and quality, it also has its own application field and working principle.

Application Field:

UPW1V471MPD aluminum electrolytic capacitors find their use in power supplies and inverters, low-voltage DC-DC converters and other related systems, offering the ideal application range for reliable power supplies. Additionally, these capacitors are ideal for decoupling input and output voltages since they can be used to store a charge - or multiple charges - and smooth the ripple waveforms and reduce ESR, thus increasing reliability in these applications.

Working Principle:

As a conventional aluminum electrolytic capacitor, the UPW1V471MPD capacitor also utilizes a chemical reaction between a solid aluminum anode foil, on which an insulation layer (oxide) is formed, and an electrolytic cathode paste, to create a very thin electrolyte barrier.

The capacitance of the UPW1V471MPD aluminum electrolytic capacitor depends on the surface area of the aluminum foil and the thickness of the aluminum oxide film. This allows a very small cell to be constructed while still yielding a higher capacitance than other types of capacitors.

The UPW1V471MPD aluminum electrolytic capacitor is a radial leaded type and has a polarized design, meaning that one terminal is positive and the other is negative. Also, when the capacitor is installed, the highest voltage must be applied to the positive terminal.

As with other aluminum electrolytic capacitors, the UPW1V471MPD capacitor also has limited life and needs to be replaced periodically. This capacitor with higher capacitance can last longer than the other aluminum capacitors, but with lower capacitance values, the capacitor has a shorter life, due to greater internal heat generation.

Also, the UPW1V471MPD aluminum electrolytic capacitor has a high ESR rate, which is two to three times that of tantalum electrolytic capacitors. The advantage of this is that it allows for high capacitance values and higher ripple currents, while the downside is a need for larger input filters to achieve the same level of ripple reduction.

In conclusion, the UPW1V471MPD aluminum electrolytic capacitor is a reliable, long-lasting and useful capacitor primarily used in power supplies, inverters, low-voltage DC-DC converters and other related systems. It utilizes a solid aluminum anode with an insulation layer (oxide) and electrolytic cathode paste, to create a very thin electrolyte barrier with high capacitance values and less impedance. While it is more expensive than other types of capacitors, it offers reliability, performance and quality for the applications it is designed for.
