Aluminum - Polymer Capacitors

Aluminum-polymer capacitors are a new generation of capacitors, having the ability to offer improved performance with higher capacitance, higher temperature range and longer operational lifetimes compared with the traditional electrolytic types. These devices are in demand due to their higher reliability, lower cost and better performance under given conditions. Designers looking for small and lightweight capacitors for their applications are finding aluminum-polymer capacitors to be the most viable choice.

EEF-UE0E221R application field and working principle

The EEF-UE0E221R aluminum-polymer device offers an exceptionally high capacitance of 220uF in a small package size that makes it suitable for many portable applications. The device provides an ideal steady-state voltage of 16V and a maximum surge voltage of 20V. It is widely used in a variety of applications such as motor control, power supply, lighting and audio circuits, and in other high frequency or high temperature applications. The device is available in both through-hole and surface mount packages.

The working principle of the EEF-UE0E221R involves two aluminum sheets separated by a thin sheet of polymer material. As the applied voltage increases, the aluminum plates form an anode and a cathode, which in turn increase the electrical field between them, thus creating an electric charge on the capacitor. This charge is then used to store energy and allow for efficient current flow between the terminals. Additionally, the thin layer of polymer material helps increase the capacitance values compared to those of traditional aluminum electrolytic capacitors.

In addition to the high capacitance values and its reliable performance, the EEF-UE0E221R is also noted for its excellent temperature range and long operational lifetime; it is capable of operating at temperatures ranging from -25°C to 85°C, making it suitable for use in extreme conditions. Moreover, it offers a lifetime of up to 5000 hours, making it well suited for use in long-term applications.

By offering superior performance compared to traditional electrolytic capacitors, the EEF-UE0E221R aluminum-polymer capacitors are proving to be a dependable and cost-effective choice for today’s designers. With its high capacitance and temperature range, along with its long operational lifetime, it offers an ideal solution for many applications.
