Tantalum Capacitors

The 893D336X0016D2TE3 is a type of Tantalum Capacitor. Tantalum capacitors, also known as Tantalum electrolytic capacitors, are widely used for their high capacitance values and small footprint. Unlike most conventional capacitors, which rely on dielectric materials such as aluminum oxide to store electrical charge, tantalum capacitors use the Tantalum metal as the source of charge storage.

Tantalum capacitors offer several advantages over other types of capacitors. For example, they have lower ESR (equivalent series resistance) than aluminum electrolytic capacitors. This allows them to handle higher ripple currents compared to conventional capacitors, making them suitable for use in switch-mode power supplies. In addition, Tantalum capacitors offer high capacitance density, making them ideal for use in portable electronics where space constraints are a priority. They also have a wide operating temperature range and are highly resistant to chemical corrosion, making them suitable for use in industrial and automotive applications.

Application Fields

The 893D336X0016D2TE3 is a high temperature, polarized Tantalum capacitor designed for use in a variety of applications. It is commonly used in automotive, industrial, medical, and consumer electronics for power filtering, bypassing, decoupling, and timing applications. It is also suitable for use in LED lighting, power supplies, DC-DC converters, DC-AC inverters, and power factor correction circuits.

This particular capacitor is a MnO2 type tantalum capacitor, which is also known as a solid-electrolyte capacitor. It offers excellent drop voltage performance, low leakage current and low ESR, making it well suited for high frequency voltage conversion applications.

Working Principle

Tantalum capacitors are based on the principles of electrochemical double-layer capacitance. The capacitor consists of two layers of electrodes, with one of the layers using the tantalum metal as the source of charge storage. A thin film of tantalum oxide is grown on the surface of the tantalum metal, which acts as a dielectric material for storing electrical charge. When a voltage is applied across the electrodes, a charge accumulates in the dielectric film which acts as the storage medium.

The magnitude of the voltage that is needed to form the electric double layer and store electrical charge in the dielectric film is referred to as the “Breakdown Voltage” or “Rated Voltage” of the capacitor. It is important to note that the breakdown voltage is higher for MnO2 type capacitors compared to other types of Tantalum Capacitors. This allows them to handle higher voltages and makes them suitable for use in a wide variety of applications.

When a capacitor is discharged, the current flows through a low-resistance conductive layer at the dielectric/electrode interface. This current flow is known as “leakage current”, and it is important to choose a capacitor with a low leakage current if the capacitor is going to be used in a sensitive electronic circuit.

Finally, it is important to note that Tantalum capacitors operate in “polarized” mode, meaning that they must be connected in a circuit with the correct polarity. Failing to do so may cause irreversible damage to the capacitor.

Conclusion

The 893D336X0016D2TE3 is a high performing Tantalum capacitor which is suitable for use in a variety of applications. It is based on the principles of electrochemical double-layer capacitance, and offers unprecedented levels of capacitance density, excellent drop voltage performance, low leakage current and low ESR values. It is important to note that it must be connected in a circuit with the correct polarity.
