Tantalum capacitors are a type of electrolytic capacitor composed of tantalum as the anode and a material with a high work function such as manganese dioxide or conductive polymer as the cathode. They are widely used in electronic circuitry due to their small size and high capacitance per volume. The M39003/01-6156/HSD is a surface mount tantalum capacitor developed by Vicor Corporation. It is designed to meet the demand for high-density, high-frequency, high-voltage applications.

Features and Benefits of M39003/01-6156/HSD

• High temperature, long life: The M39003/01-6156/HSD has a maximum operating temperature rating of +105°C with a long life rating of 1000 hours for 35V operation at +85°C.

Applications for M39003/01-6156/HSD

The M39003/01-6156/HSD is suitable for a wide range of high-density, high-frequency, high-voltage applications. It can be used in digital and analog circuits, from computers and telecommunications systems to motor drives and power supplies. The device is used to bypass higher voltages for increased noise immunity, to smooth ripple on power rails, and to provide smoothing of pulsed currents.

Working Principle of M39003/01-6156/HSD

At its most basic level, a capacitor stores electrical energy in an electric field when voltage is applied across its leads. The voltage applied causes electrons to flow from one electrode, called the anode, to the other, called the cathode. The material used for the anode affects the capacitance. The M39003/01-6156/HSD uses tantalum for the anode material, which offers high capacitance per volume and longer life than other materials.

The cathode material is chosen based on its work function, which is the amount of energy required to move an electron from one state to another state. The M39003/01-6156/HSD uses either manganese dioxide or conductive polymer as the cathode material. These materials have a high work function and allow the device to handle higher voltages. In addition, they provide a stable layer of film that prevents the anode from oxidizing, leading to longer life.

Conclusion

The M39003/01-6156/HSD is a surface mount tantalum capacitor designed for high-density, high-frequency, high-voltage applications. It features a small size, high capacitance, and high voltage rating. The device offers designers a range of application possibilities, from computers and telecommunications systems to motor drives and power supplies. Its construction, with tantalum for the anode and manganese dioxide or conductive polymer for the cathode, arrests oxidation and enables higher voltage operation.
