Tantalum – Polymer Capacitors

Tantalum capacitors are miniature, surface-mounted capacitors with a range of features, making them suitable for diverse applications across the electronics industry. These capacitors use tantalum metal as the anode and an electrically conductive polymer as the cathode. The M551B128K050AH is a surface-mount chip capacitor, specifically designed for use in cell phones, digital cameras and other mobile applications. In this article, we will discuss the application field and working principle of the M551B128K050AH tantalum capacitor.

Application Field of The M551B128K050AH Tantalum Capacitor

The M551B128K050AH is a miniaturized, high-performance surface-mount chip capacitor. Its small size allows it to be a perfect fit for low profile, modern electronic designs. The M551B128K050AH is suitable for applications in cell phones, digital cameras and other mobile devices, where its small size allows it to be integrated covertly. Other applications that this capacitor can be used in include power supplies and noise filtering circuits.

Working Principle of The M551B128K050AH Tantalum Capacitor

The M551B128K050AH tantalum capacitor works through electrochemical double-layer capacitance (EDLC) processes. In this process, an anodized tantalum film is used as the anode and an electrically conductive polymer is used as the cathode. This makes for a very reliable capacitor with high capacitance per volume, as well as good temperature and environmental properties. EDLC also allows for a very fast rate of charge and discharge, making this capacitor ideal for high frequency applications.

When an electrical voltage is applied across the M551B128K050AH tantalum capacitor, an electric field is created, which populates the area between the anode and the cathode with negative and positive ions, thus forming an electric double layer. This process stores electrical energy within the capacitor and is known as electrochemical double-layer capacitance. The stored energy is proportional to the applied voltage and is discharged, when the capacitor is disconnected from the electrical source.

Conclusion

The M551B128K050AH is a surface-mount chip capacitor, specifically designed for use in cell phones, digital cameras and other mobile applications. It is a miniaturized, high-performance capacitor with a small size, which allows it to be integrated covertly. Its working principle is based on electrochemical double-layer capacitance (EDLC), which allows for a very fast rate of charge and discharge, making this capacitor ideal for high frequency applications.
