Introduction

Aluminum electrolytic capacitors are electrochemical capacitors with polarized (anodic) aluminum oxide as the dielectric. These capacitors have very high capacitance values per unit volume, and are used mainly as energy storage in electronic devices. The UHN0J332MPD (Ultra High Temperature Hybrid) is a type of aluminum electrolytic capacitor featured in a two-terminal device. This capacitor offers and unique combination of high temperature performance and low leakage making it suitable for use in various applications.

Application Field

The UHN0J332MPD is used in applications that require higher temperature and high voltage tolerance. It is ideally suited for high temperature, severe environment, and extreme pressure, while being expected to be highly reliable. This capacitor is used for various automotive, telecommunications, and military applications. These applications range from automotive safety navigation systems and energy storage for automated meter reading systems, to military communications systems and satellite power distributions. It is also suited for use in power supplies, high power transmitters, and in other applications that require a long-term reliability in various harsh environments.

Working Principle

The UHN0J332MPD works on the principle of using a combination of an anionic aluminum oxide and a conductive polymer as the dielectric between two different terminals. This dielectric layer acts as the barrier between the two terminals, and allows electricity to flow through the capacitor while still blocking current flow. The anionic aluminum oxide undergoes a process known as dielectric relaxation which provides the capacitor with low leakage and high temperature tolerance. This process is when the oxide layer breaks down in the presence of high temperatures and then self-heals itself when the temperature is low enough. The conductive polymer of the capacitor acts as a barrier between the aluminum oxide and the two terminals, allowing the capacitor to store the electricity in the form of an electric charge. The UHN0J332MPD has a built-in temperature protection feature which helps to keep the capacitor from ever getting too hot.

Conclusion

The UHN0J332MPD is a type of aluminum electrolytic capacitor that offers a unique combination of high temperature performance and low leakage. It is used for various automotive, telecommunications, and military applications that require high temperature and high voltage tolerance. This capacitor works on the principle of using an anionic aluminum oxide and a conductive polymer as the dielectric between two different terminals. In addition, the UHN0J332MPD has a built-in temperature protection feature which helps to protect it from overheating.
