Aluminum - Polymer Capacitors

Capacitors are widely used in applications such as electronics, audio, medical, power electronics, aerospace and automotive. The EEF-UE0J181ER is one example of an aluminum-polymer capacitor. This type of capacitor is known for their high energy density, low equivalent series resistance (ESR), excellent temperature cycling characteristics and long service life.

Application Field of EEF-UE0J181ER

The EEF-UE0J181ER is a high-performance aluminum-polymer capacitor designed for use in applications where reliable power is especially crucial. The EEF-UE0J181ER is designed for use as an output capacitor in DC-DC converters in power supplies, where it can improve the stability of the system, reduce EMI interference and efficiently filter ripple current.

It is also used in applications requiring fast response time, such as UPS systems, solar photovoltaic inverters, AC motor speed control systems, LED lighting, etc. It also has applications in railway and automotive devices, as well as in high-voltage and other industrial systems. Other application fields include military, naval and air transport.

Working Principle of EEF-UE0J181ER

The EEF-UE0J181ER is composed of two layers, the inner layer is aluminum foil and the outer layer is polymer resin. The two layers are separated by an insulator. When a voltage is applied, electrons from the outer layer (the negative layer) will move through the insulator and accumulate on the inner layer (the positive layer). This is what forms a capacitor and stores energy.

The EEF-UE0J181ER has a higher capacitance, higher current (ripple) capacity and lower resistance than other aluminium polymer capacitors. It is also able to handle high-frequency noise, which results in a lower EMI. The low ESR can effectively filter ripple current and reduce power losses. The low equivalent series inductance (ESL) also helps to maintain high switching speed and reduce EMI.

The aluminum-polymer capacitor is also very stable in extreme temperatures and has good shelf life. The EEF-UE0J181ER has an operating temperature range of -55C to +85C, making it suitable for a wide range of applications. The capacitor is a reliable solution for applications in which reliability and stability are a concern.

The EEF-UE0J181ER is a reliable and robust solution for applications demanding minimal power loss, resistance to high-frequency noise, stabilization of power supply and fast response. Its high capacitance, low equivalent series resistance and high current (ripple) capacity make it an ideal choice for a wide range of applications, including medical, military, automotive and air transport.
