Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitors that contain electrodes of tantalum metal and a dielectric of an electrolyte. They offer high capacitance and low ESR (equivalent series resistance) values, making them excellent for applications that require high energy storage capacity and low changes in voltage levels. The M39003/09-0246/HSD is a type of tantalum capacitor that has a surge voltage of 160 V, a capacitance range of 10–100 μF, and an operating temperature range of -55°C to +85°C.

Construction

Tantalum capacitors are composed of two electrodes, known as the anode and the cathode, and a dielectric formed from an electrolyte. The anode is a high-purity tantalum extrusion, which is wire-shaped in cross section. The cathode is typically aluminum foil or silver-plated copper foil. The electrodes are separated by a porous dielectric, also known as the tantalum oxide, which is developed by applying a voltage across the electrodes. This creates a structure known as a rock-solid oxide (RSO), which provides excellent insulation. The main component of a tantalum capacitor’s dielectric is oxide-based, which is formed by a chemical reaction between the tantalum and oxygen.

Application Field

Tantalum capacitors are used in many different types of applications, such as in electronic circuits, pulsed power supply systems, and pulse generation. In electronic circuits, they are used to improve signal integrity, reduce power losses, and provide energy storage. In pulse generation, they are used to smooth both the input and output signals of the circuits. In high energy system, they are used in place of conventional aluminum electrolytic capacitors to provide higher capacitance, lower equivalent series resistance (ESR) values, and a greater capacitance density. The M39003/09-0246/HSD is well-suited for these applications because it offers a high surge voltage of 160 V, a capacitance range of 10–100 μF, and an operating temperature range of -55°C to +85°C.

Working Principle

Tantalum capacitors operate on the same basic principle as all other electrolytic capacitors. When external voltage is applied, current flows through the electrodes and dielectric, which causes an electrostatic field to form between the electrodes. This electrostatic field stores energy, which can be released as current when the external voltage is removed. The dielectric of the tantalum capacitor is much more stable than that of aluminum electrolytic capacitors because it does not swell or shrink over time, and it is not affected by temperature fluctuations. This long term stability is one of the main advantages of the tantalum capacitor.

Conclusion

In conclusion, tantalum capacitors are an excellent choice for a wide range of applications. The M39003/09-0246/HSD is a type of tantalum capacitor that has a surge voltage of 160 V, a capacitance range of 10–100 μF, and an operating temperature range of -55°C to +85°C, making it ideal for applications that require high energy storage capacity and low changes in voltage levels. It operates on the same basic principle as other electrolytic capacitors, and provides great long-term stability thanks to its rock-solid oxide dielectric.
