The capacitor is excellent for decoupling, filtering, and power-supply related applications. Its rugged construction and corrosion resistance make it ideal for high temperature environments and extended exposure to chemicals or high moisture content.

The M39003/01-7089H capacitor can also be used in switching supplies, power supplies, and as a dc/dc converter in military and aerospace electronics. This type of capacitor is also often used to filter out impurities in signal processing circuits and power supplies.

Working Principle

The M39003/01-7089H tantalum capacitor is constructed with two electrodes, an electrolyte, and a metal oxide dielectric. When a voltage is applied, charge carriers are drawn from the electrolyte to the anode electrode. This creates an electric field between the two electrodes and a capacitance is formed. The capacitance value is proportional to the surface area of the electrodes and the dielectric constant of the metal oxide dielectric.

When the capacitor is used for its intended purpose, voltage is applied to the terminals and it is allowed to charge up to the rated voltage. This charge creates an electric field that stores energy and is then discharged as a current through the capacitor in response to changes in voltage across the terminals. When the voltage is removed, the charge dissipates and the capacitor returns to its initial state.

Conclusion

The M39003/01-7089H tantalum capacitor is a highly reliable and durable component with a variety of applications in industrial and military/aerospace applications. Its rugged construction and corrosion resistance make it ideal for high temperature and harsh environments. The capacitor works by storing charge in an electric field created by two electrodes and a dielectric. The capacitance value of the capacitor is proportional to the surface area of the electrodes and
