Working Principle

Tantalum capacitors, including the M39003/01-2541/HSD series, are constructed from two polarised electrodes. The positive electrode consists of tantalum metal, which is deposited in a thin film onto a negative electrode, typically made of conducting polyester. The two electrodes are then separated by a coating of tantalum oxide (Ta2O5), which provides the insulation for the capacitor.

When an electric potential is applied to the capacitor electrodes, a very thin electrical layer, or space-charge layer, forms between the two electrodes. This space-charge layer is formed due to the charge separation caused by the applied potential. As the charge is stored in this space-charge layer, it acts like a capacitor in a conventional circuit. The capacitance value of the capacitor is determined by the thickness of the tantalum oxide and the overlap of the two electrodes.

Tantalum capacitors of the M39003/01-2541/HSD series are highly reliable and have excellent temperature stability due to the oxide dielectric. This increased reliability and temperature stability makes them suitable for a wide range of applications.

Conclusion

The M39003/01-2541/HSD series of tantalum capacitors is widely used in a variety of electronic applications due to their superior low ESR and temperature stability. The capacitors in this series are also suitable for military and aerospace applications due to their reliable performance. The working principle of the capacitors is based on the formation of a space-charge layer between the two electrodes when a potential is applied. This layer acts like a capacitor in a conventional circuit and provides the capacitance value for the device.
