Tantalum Capacitors

Tantalum capacitors are widely used in various electronic circuits, such as power supplies, switching power supplies, portable electronic devices, computers, medical equipment, and instrumentation. With technological advancement and increasing miniaturization, new types of tantalum capacitors—such as 13008-042MESC—continue to appear in the market. This article briefly discusses the application fields and working principles of the 13008-042MESC.

Applications

13008-042MESC tantalum capacitors are mainly used in electronic products that require low equivalent series resistance (ESR) and high temperature resistance. For instance, they can be used as oscillator circuit filtering elements in mobile phones, voltage stabilizing elements in PDAs, charge pulse stabilizing elements in high-efficiency LED driver circuits, power supply input and output filtering elements in audio amplifiers, and signal uniformation elements in camera and automotive electronic systems.

Working Principle

As a special type of capacitor, 13008-042MESC employs an aqueous electrolytic solution filled within a porous tantalum anode and a solid manganese dioxide cathode. During operation, electronic current passes through the separator and the aqueous electrolyte, producing ions and causing an instantaneous and reversible electrochemically controlled reaction at both ends of the capacitor. This reaction causes positive ions to accumulate on the tantalum anode and negative ions to accumulate on the manganese dioxide cathode. This causes a charge to accumulate and form a capacitance with a certain capacitance value between the two electrodes, thereby enabling the capacitor to function normally.

Conclusion

13008-042MESC tantalum capacitors are ideal for use in various high-temperature electronics applications, such as mobile phones, PDAs, LED drivers, audio amplifiers, cameras, and automotive electronic systems. The capacitors use an aqueous electrolyte-filled porous tantalum anode and a solid manganese dioxide cathode that reacts with an electronic current, allowing positive ions to accumulate on the anode and negative ions to accumulate on the cathode. In conclusion, 13008-042MESC tantalum capacitors offer robust, reliable performance that makes them a great choice for high-temperature electronics applications.
