Aluminum Electrolytic Capacitors: UHE1A471MPD1TD Application Field and Working Principle

Aluminum Electrolytic Capacitors (AECs) are electronic components that serve numerous use cases across a broad range of industries. Oftentimes, engineers will choose a specific capacitor type and model specifically for the application. UHE1A471MPD1TD is a popular electrolyte capacitor from Panasonic that can be used for many application fields due to its flexibility, reliability and high endurance. This article will discuss the application fields and working principle of UHE1A471MPD1TD.

Application Fields

UHE1A471MPD1TD is intended for use in a wide range of applications across multiple industries. It is suitable for use in consumer electronics such as televisions, phones, and other consumer appliances. It is also a popular choice for Power-over-Ethernet or PoE applications. This capacitor provides a low ESR, high ripple current and high endurance, which makes it an ideal choice for a PoE application. The UHE1A471MPD1TD is also recommended for use in automotive electronics. It is designed to provide excellent vibration and shock resistance and has a wide temperature range making it suitable for use in a variety of automotive environments.

Working Principle

AECs like UHE1A471MPD1TD are constructed using two aluminum foil electrodes with a paper as a separator between them. One of the electrodes is saturated with an electrolyte. The electrolyte is typically a mixture of potassium hydroxide, ethylene glycol, and water. The capacitor stores energy by allowing electrons to flow from one foil to the other. To increase the capacitor\'s efficiency, it also uses a thin oxide barrier layer on the foils to reduce leakage. When voltage is applied across the capacitor, the oxide layer produces a dielectric barrier which increases the capacitance.

The capacitor\'s construction also features a self-supporting crimping mechanism to ensure a secure connection. This helps keep the capacitor\'s performance stable, even in extreme temperature conditions. The capacitor is also polarized, that is, it requires a specific polarity with positive and negative leads. It\'s important to note that attempting to reverse the polarity of the capacitor can cause permanent damage.

Conclusion

The UHE1A471MPD1TD from Panasonic is a versatile aluminum electrolytic capacitor that can be used in a wide range of applications. It has a low ESR, high ripple current and high endurance, making it suitable for many types of applications, including consumer electronics, power-over-ethernet and automotive electronics. The capacitor features a self-supporting crimping mechanism and a thin oxide barrier layer to increase its efficiency. It is also polarized and must be connected properly to avoid damaging the capacitor.
