Tantalum capacitors, also known as tantalum electrolytic capacitors, are miniature electronic components with a small physical size and reliable electrical properties. T86D685M035EAAL is one of the most popular types of tantalum capacitors. It is commonly used for all sorts of applications due to its relatively low cost, small size, and high capacitance.

What are Tantalum Capacitors?

Tantalum capacitors are a type of electrolytic capacitor that contains a solid conductive oxide material, usually tantalum pentoxide, serviced by an electrolyte and placed between two electrodes. The two electrodes are typically constructed from a metal base and a porous base coated with an insulating layer. The solid conductive oxide layer acts as a dielectric and is responsible for the capacitor’s capacitance, the amount of charge it is able to store.

Tantalum capacitors have a wide variety of uses due to their small size, relatively low cost, and high capacitance. They are typically used in power supplies and other high-voltage applications. They are also used extensively in the production of electronic circuits, such as microprocessors, and are often used in place of aluminum electrolytic capacitors for better noise suppression in audio equipment. They are also found in digital cameras, cell phones, and other consumer electronic devices.

T86D685M035EAAL Application Field and Working Principle

The T86D685M035EAAL tantalum capacitor is a type of radial-leaded capacitor. It is most often used in high-voltage, high-current applications and is designed to provide reliable, stable electrical energy storage for computers and other electronic equipment. This type of capacitor has an insulating oxide layer between its two electrodes, which help to protect against electrical shorts due to voltage fluctuations. This oxide layer is also responsible for the capacitor’s capacitance, which is the amount of electrical charge it is able to store.

The T86D685M035EAAL capacitor is composed of a tantalum powder core, two layers of metal foil (the internal terminals and external jacket), and an electrolyte serviced by an insulating oxide layer. When a voltage is applied to the capacitor, the metal layer between the two rods will become negatively charged and the electrolyte will cause the oxide layer to grow thicker, creating a higher capacitance. Conversely, when the voltage is removed, the charge dissipates and the oxide layer shrinks, causing the capacitance to decrease.

The T86D685M035EAAL has a wide range of applications due to its low cost and reliable performance. It is commonly used as part of power-supply filtering and is also the main component of a regulator’s output stage. In addition, it is used to decouple and noise suppress sensitive circuits, such as those found in cell phones, computers, and audio equipment. It is also used for fast-charge and discharge applications, such as motor drives and battery management systems.

Advantages and Disadvantages of Tantalum Capacitors

Tantalum capacitors offer several advantages that make them attractive for a variety of applications. They have a relatively large capacitance-to-volume ratio compared to other types of capacitors, which makes them ideal for applications where space is limited. They are also reliable in operation and resistant to thermal and electrical shocks. In addition, they are quite reasonably priced and are available in a wide variety of sizes and capacitance values.

However, tantalum capacitors also have some drawbacks. They have a relatively low maximum voltage rating compared to other types of capacitors, which limits their usefulness in certain high-voltage applications. They are also sensitive to electric fields, which can reduce their effective capacitance. Finally, they are more prone to failure than other types of capacitors if exposed to extreme temperatures or excessively high voltages.

Conclusion

Tantalum capacitors are widely used in a variety of electronic applications due to their small size, reliable performance, and relatively low cost. The T86D685M035EAAL is one of the most popular types of tantalum capacitors, and is used in high-voltage, high-current applications to provide reliable power filtering and decoupling. Despite its advantages, it does have some drawbacks, including a relatively low maximum voltage rating and sensitivity to electric fields. Nevertheless, it remains an excellent choice for a variety of applications.
