Aluminum - Polymer Capacitors

Aluminum - Polymer Capacitors are an important component of many electrical systems, and their applications span a wide range of industries. The specific component to be discussed is the 158ULR2R5MFH – a rugged, high-performance aluminum-polymer capacitor. This component not only offers exceptional performance, but also offers excellent protection against EMI, surge, and other environmental factors.

Aluminum - Polymer Capacitors are developed by combining the dielectric properties of an electrolytic with the low-leakage and low-inductance capabilities of a film capacitor. A true aluminum-polymer capacitor combines the two components into one self-contained package, enabling it to meet the needs of high-power applications where size and cost are a factor. The 158ULR2R5MFH utilizes this combination of material sets, allowing it to offer the optimal combination of performance and reliability for applications requiring high-current capability.

Application Field

The 158ULR2R5MFH is ideal for use in high-power applications such as motor control, power supplies, motor drives and UPS systems. Its wide operating temperature range, high ripple current and high volumetric efficiency make it an ideal choice for both industrial and domestic applications. The capacitors are also able to maintain their low-ESR performance over a wide range of frequencies, and as such they can be utilized in a variety of applications, such as wall-mount power supplies, automotive power supplies, board-level power supplies, medical equipment and space systems.

Working Principle

The 158ULR2R5MFH utilizes an aluminum-alumina dielectric material which allows it to offer high capacitance values in a relatively small package. The combination of materials permits high-ripple current characteristics and low-leakage performance with fast pulse response. The capacitor includes a floating anode design, allowing it to perform safely and efficiently at both low- and high-voltage applications. The anode is separated from the cathode by a dielectric material which prevents current from flowing from the anode to the cathode; thus allowing for maximum efficiency at low-voltage applications.

In addition, the combination of highly-insulating aluminum-alumina dielectric material, combined with the internal structure of the 158ULR2R5MFH, allows for a low-impedance input for low-voltage applications – thereby providing maximum output during operation. At higher voltages, the chamber has been designed to be robust and is able to with stand very high temperatures. This ensures reliable operation regardless of the applied voltage.

The 158ULR2R5MFH capacitor is designed to provide high-performance in a wide range of applications, such as motor control, power supplies, UPS, AC/DC inverters, welding, and other similar applications where size and cost are a primary factor. As such, these capacitors are highly reliable, robust, and easy to use for a wide range of applications.
