Tantalum - Polymer Capacitors revolutionized the world of small electronics with their relatively high capacitance, low profile and long, reliable service life.The M550B108K040AH, a special tantalum polymer capacitor, is a significant representative of the revolutionizing trend. It has a wide range of application fields and a reliable working principle, engendered the capability of this type of capacitor to place high chemial, physical and electrical parameters.

Application Fields

The M550B108K040AH is a leaded Electrolytic Capacitor and is primarily used in high-power applications. Due to its small size and high packing density, it is ideal for use in portable and mobile device applications, such as cell phones and other portable electronics. Also, with the low ESR and ESI characteristics, it can also be used in RF and AFC applications for filters, power amplifiers, and baseband signal oscillators. Moreover, this kind of capacitor can be found in power management applications, such as dc-dc converter circuits, and analog signal applications like adjustable speed drives.

Working Principle

Tantalum - Polymer Capacitors, such as the M550 B108K040AH, use Tantalum Oxyhydroxides as the electrodes and have organic polymers as the electrolyte. The effects of the organic polymer electrolyte in this capacitor allow for an extremely high capacitance density, up to 10X greater than traditional tantalum capacitors. This effect also allows for much lower equivalent series resistances and equivalent series inductances, thus providing superior ripple current and low profile characteristics.

The working principle of the M550 B108K040AH is that it has two electrodes, an anode and a cathode, both connected by two merges of electrolyte and separated by a polymer dielectric separator. When voltage is applied across the capacitor, the anode of the capacitor is attracted to the more positive potential of the applied voltage, while the cathode of the capacitor is attracted to the more negative potential. This generates an opposing polarization effect, which creates an electric field, which further increases the dielectric permittivity and thus causes the build-up of charge on the electrodes.

The electric field not only enhances the capacitance but also yields increased efficiency of the electric charge cycling due to the improved electric conduction. What’s more is that the polymer dielectric separator between the two electrodes is made of a unique, proprietary polymer with excellent thermal properties and low leakage current, which helps to enhance the capacitor’s performance and longevity.

Conclusion

The M550 B108K040AH is a reliable and powerful representation of the Tantalum - Polymer Capacitors. It is primarily used for high-power applications due to its small size and high packing density as well as its superior electrical characteristics. In addition, due to its unique construction and special organic polymer electrolyte, the M550B108K040AH offers excellent reliability and increased capabilities. With application fields ranging from RF and AFC to analog signal applications, the M550 B108K040AH has proven to be a powerful and efficient tool in the world of electronic components.
