M39003/01-3174/HSD application field and working principle

Tantalum capacitors, also known as Ta-Caps, are one of the most common types of capacitors used today. They are widely used in both analogue and digital circuits, primarily due to their small size, low cost and relatively large capacity. Tantalum capacitors offer high-frequency characteristics, making them especially attractive in circuits with high-frequency demands. In addition, they have excellent electrical and temperature stability.

Working principle of M39003/01-3174/HSD

Tantalum capacitors are basically two conductive surfaces separated by a dielectric material. In the case of the M39003/01-3174/HSD, the dielectric core is composed of Tantalum pentoxide, which has a much higher breakdown voltage than other capacitors. The typical construction consists of a tantalum bead with a conductive anode and cathode material. When a voltage is applied to the anode, a thin film of electrical charge forms on the electrolyte and starts to fill the space between the cathode and the anode.

As the voltage continues, electric charge accumulates on the dielectriccoreand displaces the electrolyte within the capacitor. This creates an electric field that stores energy in the form of a dielectric film. The amount of charge stored is proportional to the amount of electric field in the dielectric core and the temperature of the environment. When there is no longer a need for charge, the capacitor can be discharged. This is done by applying an opposing electric field across the capacitor, which results in reducing the field strength, releasing the stored energy.

Tantalum capacitors are highly efficient and have a wide range of temperature, voltage, and capacitance values. They are also robust and reliable. However, they have some drawbacks. For instance, they have a short expected life, and their ability to store charge decreases with age. In addition, they are not suitable for high-frequency applications due to their slow charge/discharge rates.

Conclusion

For medical implantable and life-saving device applications, M39003/01-3174/HSD is an ideal choice for its small size and cost-effective solution. It has many advantages, including high-frequency characteristic, excellent electrical and temperature stability, and a long expected lifespan. However, it has some drawbacks, including a short expected life and poor performance for high-frequency applications.

The working principle of M39003/01-3174/HSD is based on a tantalum bead with a conductive anode and cathode material. When a voltage is applied, a thin film of electric charge forms on the electrolyte and starts to fill the space between the cathode and the anode, resulting in an electric field. When the voltage is no longer needed, the capacitor can be discharged by applying an opposing electric field. Thus, M39003/01-3174/HSD is an effective solution for medical implantable and life-saving device applications.
