Introduction

Aluminum electrolytic capacitors are electrical components that store electrical energy. They are composed of two metal plates, and alternating layers of aluminum foil and paper. As a result, the aluminum electrolytic capacitor is capable of storing charges much higher than a standard capacitor. In the case of the UPW1E272MHD, which is a high power aluminum electrolytic capacitor, its main application is in high current applications, such as power supplies and inverters.

Application Field

The UPW1E272MHD is mainly used in high power applications as it is capable of handling current ratings up to 16.5A. It is able to handle ripple currents up to 140A and DC voltage up to 400V. It is also able to withstand a wide temperature range, which makes it suitable for a variety of applications.The UPW1E272MHD can be used in a variety of applications such as, power supplies, inverters, motor drives, AC motor starters, and automotive applications. This capacitor can be used in a large array of devices and machines, that run at high efficiency and require capacitance to support the current draws. This capacitor undergoes rigorous testing for quality assurance and has been certified for safety by safety agencies like UL and CSA.

Working Principle

The UPW1E272MHD, being an aluminum electrolytic capacitor, works by storing electrons between two layers of aluminum foil, that are separated by an electrolytic paper dielectric. Theprocess consists of two electrodes, an anode and a cathode, that are immersed in an electrolytic solution. The anode is composed of an aluminum foil, while the cathode is composed of a terminating piece of foil. The anode is the positive pole and the cathode the negative pole. When a potential difference is applied between the two poles, an electric field develops. The electric field induces charge carriers in and out of the electrolyte and into the anode and cathode, creating a separation of charges (an electric dipole). This polarizes the electrolytic solution, creating a high dielectric strength.The UPW1E272MHD also features a solid conductive pad on its positive terminal, which provides excellent current dissipation for the applied current. This pad is made from a particle-filled organic resin compound. Furthermore, the connection between the pad and the capacitor body is internally secured with a stainless steel spring, enabling high power production and a greater mechanical shock resistance.

Conclusion

In conclusion, the UPW1E272MHD aluminum electrolytic capacitor is a high power capacitor that is well-suited for a variety of applications. Due to its high current handling capabilities and wide temperature range, it is great for power supplies, inverters, motor drives, AC motor starters, and automotive applications. Additionally, its solid conductive pad improves current dissipation and shock resistance. Therefore, the UPW1E272MHD is a great choice for applications requiring high power capabilities.
