Aluminum - Polymer Capacitors

397ULR6R3MFF is a type of aluminum - polymer capacitors which is composed of aluminum and organic polymer electrolyte. It operates on the principle of forming a dielectric film on an anode layer that is composed of expanded alumina. This capacitor is suitable for use in DC-DC converters, embedded applications, and consumer electronics.

Construction of 397ULR6R3MFF Aluminum-Polymer Capacitors

The 397ULR6R3MFF aluminum-polymer capacitors consist of a thick and thin aluminum foil bonded to a stainless steel wire, a dielectric film, and an anode layer. The aluminum foil serves as the cathode, while the dielectric film and anode layer serve as the bidirectional dielectric. The conductor is combined with the aluminum foil. The cathode is then insulated by the dielectric film and anode layers.

Working Principle of 397ULR6R3MFF Aluminum-Polymer Capacitors

The working principle of 397ULR6R3MFF aluminum-polymer capacitors is based on forming a dielectric film on an anode layer which is composed of expanded alumina. The current delivered to the capacitor is stored in the form of electrons in the dielectric film. The capacitor then acts as an electrical conductivity medium and dissipates the current away from the cathode.

In terms of electrical characteristics, the 397ULR6R3MFF aluminum-polymer capacitors produce much lower ESR (equivalent series resistance) than conventional aluminum electrolytic capacitors. The ESR value of 397ULR6R3MFF is lower than 0.7mΩ. This can be further reduced depending on the operating frequency and the capacitance value of the capacitors. That’s why 397ULR6R3MFF can support high-frequency power supply that requires exceeding low ESR.

Application Fields of 397ULR6R3MFF Aluminum-Polymer Capacitors

397ULR6R3MFF aluminum-polymer capacitors are designed for use as DC-DC converters in embedded applications. They also have a wide range of potential applications in consumer electronics. In consumer electronics, the capacitors are often employed in camera modules, game consoles, mobile phones, and tablet PCs. This is because these devices require a reliable and compact power supply that can operate at very high frequencies.

397ULR6R3MFF aluminum-polymer capacitors are also suitable for use in high-voltage and temperature applications due to their increased voltage resistance and excellent temperature stability. This feature makes them valuable components in the manufacture of many consumer electronics. Additionally, they provide excellent decoupling performance and noise reduction in audio applications, allowing them to be used in audio amplifiers, radio receivers, and other audio equipment.

Furthermore, 397ULR6R3MFF aluminum-polymer capacitors are suitable for use in data communication systems, such as PLCs and IT systems. This is because their low ESR allows them to stabilize voltage and reduce data noise transmission, ensuring an improved and reliable data transmission.

Conclusion

In summary, 397ULR6R3MFF aluminum-polymer capacitors are ideal for applications in DC-DC converters, embedded applications, and consumer electronics. Owing to their lower ESR, high voltage resistance, excellent temperature stability, and decoupling performance, these capacitors offer low voltage noise, high-frequency power supply requirements, stable voltage, and improved data transmission reliability in many applications. These features make 397ULR6R3MFF capacitors a great choice for any type of electrical applications.
