In this article, we will discuss the application field and working principle of the RNS1E470MDN1 aluminum-polymer capacitor.

Application Field

The RNS1E470MDN1 aluminum-polymer capacitor is an ideal choice for a variety of applications, such as decoupling and batch filtering of power supplies, smoothing of pulsed loads, and the filtering of DC ripple. This capacitor is also an ideal choice for noise cancellation and energy storage in high-load circuits. It is especially useful in applications where large capacitance values are required, such as in the production of power supplies, motor drives, switching power supplies, and consumer electronics.

Additionally, this capacitor is suitable for linear and switched-mode power supplies due to its quick response time. Furthermore, its high reliability and long life make this capacitor suitable for industrial environments and high-end consumer electronics, such as the automotive industry and computer systems. Its encapsulated construction also makes it an ideal choice for outdoor applications, as it is protected against dust, sand, vibration, and shocks.

Working Principle

The working principle of the RNS1E470MDN1 aluminum-polymer capacitor is relatively straightforward. The capacitor consists of a densely packed series of aluminum-polymer film electrodes and a charge collector. The electrodes and the collector create an electric field which stores energy. When a voltage is applied to the capacitor, the stored energy is released in the form of electrical current.

The capacitor is also polarity-sensitive, which is why it must be connected to the load in the correct orientation. In addition, the capacitor has an internal resistance known as its equivalent series resistance (ESR), which provides dynamic resistance and affects the efficiency of the power conversion circuit. This ESR also helps to limit the amount of current delivered to the load.

The RNS1E470MDN1 aluminum-polymer capacitor is a highly reliable and energy-efficient component that can be used in a wide range of applications. Its high capacitance-to-volume ratio and small form factor make it especially suitable for high-density, space-limited applications.
