Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, which offers excellent physical and electrical properties, along with high levels of reliability. They are widely used across numerous applications including computing, automotive, and portable electronics. The 135D227X9008F6 features a solid tantalum capacitor, which is often used within high frequency or low-leakage applications.

Application Field

The 135D227X9008F6 is used most frequently in computing and automotive applications, as its capacitance and voltage ratings make it an ideal choice for a variety of applications. It is also used in some portable electronics devices, such as mobile phones and GPS units. Its small size and low profile make it an attractive option for users looking for a design that can fit into small form-factors.

Working Principle

Tantalum capacitors are composed of a solid anode made from tantalum, and an electrolyte (a liquid electrolyte, or a solid-state polymer matrix).The anode material is composed of a metal oxide coating layer that forms a barrier to electrical current. When a voltage is applied across the device, a current is produced, which causes the coating layer to dissolve. This increases the number of ions in the electrolyte, which in turn leads to the formation of a conductive film along the anode. This conductive film is where the capacitance comes from.

When the voltage is removed from the device, the ions are redistributed, allowing the coating layer to form again. This returns the device to its original state, and allows it to be used again. The capacitor’s capacitance is determined by the size of the coating layer, the dielectric constant of the electrolyte, and also the internal resistance of the device.

Advantages

A few advantages of using tantalum capacitors include their high capacitance and low profile, as well as their low cost. Other advantages include the fact that they are capable of storing more charge than other types of capacitors, and their small size makes them suitable for high-density applications. Additionally, their corrosion resistance and reliability over longer periods of time make them a great choice for applications that require long-term storage of energy.

Disadvantages

Despite its many advantages, there are also some drawbacks to using tantalum capacitors. They tend to generate more heat than other capacitors, and they have a tendency to fail due to oxide depletion. Additionally, the voltage ratings of these capacitors tend to be lower than other types of capacitors, meaning that they can’t be used in applications with higher voltage requirements. Finally, the cost of tantalum capacitors is higher compared to other types of capacitors.
