567ULR2R5MEF

Aluminum-polymer capacitors are the next generation of the traditional aluminum electrolytic capacitors because they don’t suffer from the same drawbacks as traditional capacitors. The 567ULR2R5MEF aluminum-polymer capacitor is one of these capacitors and is widely used for its high capacitance, low ESR and small size.

Application Field

The 567ULR2R5MEF aluminum-polymer capacitor is mainly used in applications requiring long life, high temperatures, and small sizes. These are mainly used in the automotive industry, electric vehicles, medical equipment and renewable energy systems. The capacitor is used to store and discharge electrical energy, filtering out unwanted power and spikes, and providing high-efficiency power conversion.The 567ULR2R5MEF capacitor is also well suited for audio devices and power management applications due to its ESR and excellent frequency response properties. In addition to these, the 567ULR2R5MEF is also used as a high-end audio capacitor and widely used in high-end audio systems due to its internal capacitance and low dielectric absorption.

Working Principle

The 567ULR2R5MEF capacitors are constructed using three different layers. The first layer is an aluminum foil which acts as a conductor. The second layer is a metalized polymer film, which acts as the dielectric. The third layer is an anode foil which, like the aluminum foil, acts as a conductor. The two layers, aluminum and metalized polymer are pressed together by crimping the anode foil to produce an electrical contact. When current flows through the capacitor, electrical charges accumulate in the metalized polymer and an electrical field is created between the two electrodes, creating a capacitance. The capacitance and ESR of the capacitor is determined by the size of the metalized polymer layer, the thickness of the aluminum foil and the tension of the anode foil.

Conclusion

The 567ULR2R5MEF aluminum-polymer capacitor is a reliable, efficient and long-lasting device that is widely used in automotive, medical, renewable energy and other applications. Due to its high capacitance and ESR properties, as well as its small size, this device is particularly suitable for power management applications and audio devices. The working principle of these capacitors involves a three-layer construction and relies on the metalized polymer layer between the aluminum foil electrode and an anode foil to produce an electrical contact when current flows through the capacitor.
