Tantalum - Polymer Capacitors

T541X686M030BH8710 belongs to a series of tantalum - polymer electrolytic capacitors. Such capacitors are ultra-miniaturized polarization capacitors with significantly high temperature and voltage characteristics, and have seen considerable industry applications. This article will discuss the application fields and working principles of T541X686M030BH8710 and similar products.

Application Fields

The application fields of T541X686M030BH8710 are vast and varied. Generally, tantalum - polymer capacitors offer a high power density, stable dielectric properties, and an excellent load life characteristics; all of which make them suitable for use in many electronics components, such as power supply systems, alarm and emergency systems, medical electronics, and military applications. Moreover, the excellent quality of the polymer electrolyte also makes it applicable for low voltage hold ups, and acts as a noise filter.

Tantalum - polymer capacitors can also be used in electrical circuits as oscillator components and energy storage devices, as well as in motherboards, data lines, and portable electronic devices such as mobile phones and tablets. Furthermore, they are employed as power factor correction and smoothing components in power electronic circuitries, aiming to help supply reliable and stable power inputs to the electronic products.

Working Principle

The basic idea behind the working of all kinds of tantalum - polymer capacitors is the same- ultracapacitor principles. Electrical current is stored in the dielectric material between the two layers of electrode plates. The anode or positive electrode is usually made of powdered tantalum. This is then compacted, compacted and sintered to form a layer of tantalum oxide at the surface. The cathode or negative electrode is typically made from manganese dioxide. The charge is then stored between the two interconnected but insulated electrode layers. This process persists as long as the capacitor is charged.

T541X686M030BH8710 electrolytic capacitors also feature polarized electrolyte. One electrode is much larger in area than the other and the electrolyte is oppositely charged. This difference in electrodes helps to create a higher capacitance and polarization of molecules, resulting in a higher capacitance and better performance.

The capacitance of T541X686M030BH8710 and other similar high-voltage, low-leakage tantalum - polymer electrolytic capacitors range between 6.3 and 50V, with a maximum capacitance of 6.8 μF, and a temperature range of -25°C to +100°C. The ESR is much lower than the traditional electrolytic capacitor. Along with the high working voltage and low ESR values, this makes this type of tantalum - polymer capacitor suitable for various high frequency switching circuits.

Conclusion

Tantulum - polymer electrolytic capacitors, such as the T541X686M030BH8710, offer numerous advantages to users. In comparison to other electrolytic capacitors, they feature high power density, excellent load life characteristics, and a wide temperature range. This makes them widely applicable in many power electronic, medical, military and other circuits, as well as portable electronic devices. The basic working of such capacitors is based on the ultracapacitor principles, with a polarized electrolyte and two differently charged electrodes.
