Amongst the many aluminum electrolytic capacitors available, UTM1E470MPD is a popular choice due to its superior performance, quality, reliability, and affordability. This article details the application areas and working principles of UTM1E470MPD.

The Application Areas

UTM1E470MPD aluminum electrolytic capacitors are optimal for use in high-performance, high-reliability applications such as DC motor runs, snubber circuits, and filtering. The high-purity foil construction of the electrodes, combined with a low-resistance, low-inductance housing, ensures a high level of reliability. Moreover, the UTM1E470MPD also features a low ESR, high ripple current rating, and high temperature stability, making it suitable for use in a variety of demanding applications.

In addition, UTM1E470MPD aluminum electrolytic capacitors feature a UL 94V-0 flame retardant case material, making them suitable for use in applications where safety is a priority. Moreover, its 105°C long life design makes it suitable for use in high-temperature applications. It is also available in a variety of capacitance values, ranging from 220uF to 3300uF, making it highly versatile.

The Working Principle

UTM1E470MPD aluminum electrolytic capacitors employ the familiar principle of a two-electrode system consisting of two conducting plates separated by an electrolyte material. In this case, the two conducting plates are made of high-purity aluminum foil with a thin layer of oxide coating. When a voltage is applied, the oxide layer forms a barrier between the two electrical plates, effectively acting as a dielectric material. As a result, the capacitor can store a charge, and this charge is proportional to the applied voltage.

UTM1E470MPD aluminum electrolytic capacitors also employ a unique di-electric boot liner design in order to reduce ESR and achieve a high ripple current rating. The boot liner is flexible and heat resistant, and it is designed to perfectly fit the two electrode plates. This design helps to reduce ESR by dissipating heat quickly, and it also prevents air from entering the capacitor, which minimizes the risk of arcing and reduces the formation of harmful gases.

Conclusion

UTM1E470MPD aluminum electrolytic capacitors are great for a variety of high-performance, high-reliability applications, including DC motor runs, snubber circuits, and filtering. It features a high amperage rating, low ESR, and high-temperature stability, making it an ideal choice for a variety of applications. Additionally, its unique di-electric boot liner design helps to reduce ESR and achieve a high ripple current rating, making it even more suitable for demanding applications.
