Tantalum Capacitors

Tantalum capacitors are commonly used in electronic circuits, and have many advantages over other types of capacitors. For example, they are smaller in size and lighter in weight, which makes them ideal for use in portable or miniaturized devices. Additionally, they are relatively stable, with low temperature drift and high capacitance retention. They also have a low equivalent series resistance (ESR). The M39003/03-2072/98 device is an example of a tantalum capacitor.

M39003/03-2072/98 Application Field and Working Principle

The M39003/03-2072/98 is a high-powered, very low equivalent series resistance (ESR) disc type tantalum capacitor. They are engineered to provide reliability in extreme vibration and temperature environments, and thus are suitable for use in avionics, automotive, communications, and consumer electronics. They are available in various capacitance values, and have a wide temperature range of -55C to 130C. The design consists of an anode made of sintered tantalum powder, an electrolyte, and a cathode made up of a polyimide film and silver terminations. When voltage is applied to the capacitor, the electrolyte is the medium through which electrical conduction occurs.

The operation of the device is based on the Faraday principle. When the voltage across the device is increased, the cathode attracts the cations of the electrolyte, creating a build-up of electrical charge. This charge is then stored in the capacitor’s sintered tantalum anode, increasing the capacitance of the device. The capacitance is dependent on the area of the anode, the thickness of the dielectric, and the type of electrolyte used. When the voltage input is removed or reduced from the device, the cations then move back to the cathode, and the charge stored is dissipated.

Conclusion

In conclusion, the M39003/03-2072/98 is a high-powered disc type tantalum capacitor. It has several advantages over other types of capacitors, such as a very low ESR, small size, and higher capacitance retention even at extreme temperatures and vibrations. The working principle of the device is based on the Faraday principle, where an electrical charge is stored in the capacitor’s sintered tantalum anode when voltage is applied. The charge is then dissipated when the voltage input is removed or reduced.
