Introduction

Tantalum capacitors, also known as tantalum electrolytic capacitors, are basically all solid electrolytic capacitors whose anode is formed of sintered tantalum powder and oxide film is used as the dielectric layer. The characteristics of T86D475M050ESSS tantalum capacitors, in particular, make them ideal for applications where fast response, high levels of accuracy, and long life are essential.

Application Fields：

T86D475M050ESSS tantalum capacitors are mainly used in the following fields: automotive, audio, handheld communications, industrial control, medical instrumentation, military, mobile phone, office automation, portable audio, and test & measurement. Their specific applicationsinclude DC-DC converter, pulse transformer, Timing circuit, transmit / receive circuit, AC rectifier, switching circuit, switching regulator, timer, Flash memory circuit, IGBT inverter.

Working Principle：

The working principle of T86D475M050ESSS tantalum capacitors is based on the surface tension of a liquid electrolyte in shape of dielectric film. This film acts as the insulator between the positive and negative poles, permitting electricity to flow between them. It works similarly to the edge effect in a sintered tantalum electrolytic capacitor. When a voltage is applied to the capacitor’s terminals, electrochemical ions are generated in the dielectric, forming an electrical double layer that stores energy.

Features：

Tantalum capacitors are particularly advantageous over traditional electrolytic capacitors as they are both small and can tolerate high levels of inrush current. This makes them more reliable in applications where the voltage or power levels can unexpectedly spike. They also produce lower levels of ESR and ESL, and can have capacitance values greater than 10μF.

Advantages：

T86D475M050ESSS tantalum capacitors offer a number of advantages compared to other capacitor types:

• Small size means greater design flexibility.
• High capacitance values mean greater effectiveness.
• Lower ESR and ESL values combined with virtually no polarization/depolarization gives increased reliability.
• High capacitance stability in high frequencies and under extreme conditions.
• Good tolerance for temperature changes.
• Good tolerance for thermal shock.
• Excellent capacitance/voltage characteristics.

Drawbacks：

Tantalum capacitors do have some drawbacks, most notably their relatively high price. They are also notoriously fragile and can be damaged easily if they are mishandled or exposed to high temperatures. It is also not recommended to use them at high frequencies, as their performance may be affected.

Conclusion

Tantalum capacitors are a extremely useful type of capacitor which offers a number of distinct advantages that can make them an attractive option for certain applications. T86D475M050ESSS tantalum capacitors, in particular, offer high tolerance for temperature and thermal shock, excellent capacitance/voltage characteristics, and small size for greater design flexibility. Although their high cost may be prohibitive to some, the benefits they offer may well be worth the expense in the long run.
