UPA1E821MPD

Aluminum electrolytic capacitors are some of the most common and widely used kinds of capacitors in the world. They are also known as “electrolytic” because of the electrolyte that is used to produce them. These capacitors have been around since the early 1900s and are popular due to their excellent properties: high capacitance, low cost, and low leakage. UPA1E821MPD is an example of such a capacitor.

UPA1E821MPD is an aluminum electrolytic capacitor with Polyphenylene oxide (PPO) coating. This type of capacitor offers high capacitance in combination with a low temperature coefficient. Its minimum self-life is 4000 hours at 85 degrees Celsius. The capacitor is rated with a voltage of 160 VDC and can withstand small surcharges. In comparison to other types of capacitors, UPA1E821MPD provides more electric energy density and a wide working temperature range.

The performance of UPA1E821MPD can be further improved by adding a non-solid electrolyte and a sealant tape, making it suitable for a variety of applications. These include audio systems, DC-DC converters, switching power supplies, and LCD monitors. UPA1E821MPD can also be used in power electronics, providing low voltage ripple, high current capacity, and reliable performance.

The working principle of UPA1E821MPD is based on the electrolysis of aluminum. When two aluminum foils are immersed into an electrolyte, a chemical reaction occurs between the aluminum foil and the electrolyte. This reaction produces a magnetic field which in turn creates a voltage across the two aluminum foils. This voltage is then used to store energy in the capacitor. So, in this way, aluminum electrolytic capacitors like UPA1E821MPD are able to store charge and energy.

In conclusion, UPA1E821MPD can be classified as an aluminum electrolytic capacitor. This type of capacitor offers high capacitance and low temperature coefficient. It is versatile and can be used in a variety of applications, such as audio systems, DC-DC converters, switching power supplies, LCD monitors, and power electronics. The working principle of UPA1E821MPD is based on the electrolysis of aluminum, which produces a voltage and stores energy in the capacitor.
