Tantalum Capacitors

Tantalum capacitors are one of the most popular types of capacitors. They are used in a variety of applications, from aerospace to consumer electronics. Most tantalum capacitors are either molded or wetting sealed type, with the exception of certain Polarized, High Operating Temperature (HOT) and Low-ESR models.

A T86D106M035EBSL capacitor is a type of tantalum capacitor. It is a surface mount device with a maximum operating temperature of 125°C, and is particularly useful for military and portable electronics owing to its small size.

Application Field

Tantalum capacitors like the T86D106M035EBSL are used in a range of applications. These include mobile phones, laptops, digital cameras, automotive electronics, and aerospace. They are also used in industrial equipment, medical equipment, telecom systems, and power supplies.

One advantage of this type of capacitor is its ability to provide a high Ripple Current rating for its small size. This makes it suitable for applications where space is a limiting factor. In addition, it has a higher capacity for energy storage than other types of capacitors. This makes it a good choice for applications such as buffer capacitors, charge pumps, RF power supplies, noise filters, overvoltage protection, and delay lines.

Working Principle

Tantalum capacitors work in a similar way to aluminum electrolytic capacitors. They are constructed using two electrodes — an electrolytic anode and a solid tantalum cathode — separated by a dielectric oxide layer. The oxide layer acts as an insulator between the two electrodes, preventing the electrodes from touching, and allowing an electrical charge to be stored between them.

When an external voltage is applied to the capacitor, electrons move from the cathode to the anode. This causes an electric field to form between the electrodes. This electric field stores energy in the form of a charge. If the applied voltage is higher than the breakdown voltage of the dielectric, the capacitor will fail.

Tantalum capacitors are generally used in applications where high capacitance and low ESR is required, such as in DC-DC converters or filter circuits. This is because they have a higher breakdown voltage, greater capacitance-to-volume ratio, better temperature characteristics, and higher ripple current capacity compared to other types of capacitors.

Conclusion

Tantalum capacitors are widely used in a variety of applications. The T86D106M035EBSL capacitor, in particular, is useful for military and portable electronics due to its small size. It also offers higher capacitance and lower ESR than other types of capacitors, making it suitable for filter, overvoltage protection, and other applications.
