Tantalum capacitors can be a valuable asset to any electronic or electrical application as it offers excellent energy storage capabilities, long shelf life and density, as well as reliability, all in one small component.

At the heart of tantalum capacitors is the tantalum powder, which is composed of small molecules of the metal and is held together in a compound form. As with other capacitor materials, such as ceramic, the structure of the molecular lattice creates a lattice of capacitance, meaning the capacitance of the material is determined by the number of molecules in the lattice. When a voltage is applied across the structure, an electric field is created, which causes the molecules to move and store energy in the form of electric charge.

The working principle of tantalum capacitors is built around this simple concept. When a voltage is present on the two plates of the capacitor, one side of the capacitor receives higher voltage, thus creating a negative charge, while the other side receives lower voltage, creating a positive charge. The polarization of the capacitor means that when a voltage is present on the two plates, electrons from the negative side move towards the positive side and vice versa. As this movement of electrons continues, the charge builds up around the plates, providing an electric field. This electric field, in turn, creates an electric charge, commonly referred to as a capacitance or capacitance flow.

This charge allows the two plates to store energy for a short period of time, until the voltage is removed. This energy storage is what allows tantalum capacitors to be used in a range of electronic and electrical applications such as power supplies, DC-DC converters, and more.

The 13008-081MESA/HR is a series of tantalum capacitors designed for high-reliability, low-voltage applications.
