Tantalum Capacitors

Tantalum capacitors are specialized electronic components that are mostly used in portable devices and highly integrated circuits. These capacitors are also sometimes referred to as tantalum electrolytic capacitors and are characterised by their low dielectric constants which easily allow for very high energy densities. The M39003/09-0258H tantalum capacitors are specifically designed and manufactured for military applications. These capacitors are fairly compact in size and offer excellent chemical stability and reliability. They feature low leakage characteristics and superior electrical performance over other capacitors.The M39003/09-0258H tantalum capacitors are primarily used in military communication equipment, electronic countermeasure systems, surveillance systems, and various other military-specific applications. Because of their durability and reliable performance, they are also used in harsh and severe environments, including in missiles and on gun-mounts.

These capacitors are also extensively used in the medical and agricultural industries, as well as in renewable energy systems.

Working Principle

Tantalum capacitors work by storing energy in the form of an electric field which is created between two ions held in an insulation medium. This insulation medium is usually made from a tantalum alloy or an oxide material.The M39003/09-0258H variant is usually composed of a steel-clad anode plate and a palladium-coated cathode plate. The two plates are separated by a dielectric layer made from a tantalum pentoxide material.When a voltage is applied to the capacitors, an electric field is created between the two plates. The anode plate is connected to the positive voltage terminal, while the cathode plate is connected to the negative voltage terminal. The electric field created between the two plates induces an electrostatic charge in the dielectric layer. This charge remains stored until the voltage is removed, when it is dissipated through a reverse current. The capacity of the M39003/09-0258H tantalum capacitors is determined by the area of the plates, the type of dielectric layer, and its thickness. These capacitors are usually rated at 6.3 volts and can safely handle voltages up to 10 volts.
