Tantalum capacitors (often termed Ta-capacitors or simply Ta-caps) are small electronic components that store electrical energy in much the same way traditional capacitors do, but use a different material (in this case Tantalum) to obtain its capacitance. To understand what they are, why they can sometimes be preferable to other capacitors, and the functionality of the TM8M105K010UBA, one must first understand the basics of capacitors.

Capacitors are essential electronic components that are frequently used in applications like power supply filtering, energy storage, signal coupling, de-coupling, and power factor correction. The capacity of a capacitor is measured in Farads and is defined as the amount of electrical charge (in coulombs) that an element can store for a given voltage. In an electrical circuit, a capacitor acts like a sponge that absorbs energy and holds it for a while. To store and, more importantly, release this energy may have a number of different applications.

The TM8M105K010UBA is a high-temperature, surface-mountable tantalum capacitor with an anode termination. It is manufactured by Champion Electronics using a process called anodic termination which provides superior performance, higher working voltages and better capacitance stability. It is designed for use in high temperature, high voltage applications, such as high performance current-source/current-sink amplifiers, electric motor controllers, power supplies, and switch-mode power supplies, among other applications.

The working principle of the TM8M105K010UBA is fairly simple. When a voltage is applied across the anode and cathode surfaces, charge accumulates on each surface. The charge disagrees, causing a separation of charge between the anode and the cathode. This separation of charge creates an electric field and an associated electric potential. This potential creates and stores energy, thus, the capacitor’s capacitance. The capacitor works in a manner analogous to an ion exchange, where one of the electrodes accumulates charges and the other loses them.

The capacitance of the TM8M105K010UBA is provided by the amount of area between the anode and the cathode. The capacitance of the TM8M105K010UBA is large enough to handle high voltage applications, such as motor controllers and power supplies. The TM8M105K010UBA also provides superior insulation as well as low ESR and ESL values, making it an ideal choice for high frequency applications. The TM8M105K010UBA also has low inductance, which is important for high speed signal processing applications.

In summation, the TM8M105K010UBA is a high-temperature, surface-mountable tantalum capacitor with superior capacitance performance, high working voltages, and low ESR and ESL values. It is ideal for high voltage power supply filtering, energy storage, signal coupling, de-coupling, and power factor correction applications, due to its large capacitance, superior insulation, and low inductance.
