Tantalum Capacitors

A tantalum capacitor, also called a tantalum electrolytic capacitor, is a type of electrolytic capacitor, which is an electronic component. It consists of a pellet of tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by liquid or solid electrolyte as a cathode.

M39003/03-0448/TR application field and working principle

The M39003/03-0448/TR is a radial leaded, solid tantalum capacitor with a reduced case size, which can be used in applications such as automotive, industrial and high temperatures. It features increased power dissipation rating and high reliability compared to other types of capacitors, allowing it to be used in high temperature circuits. The M39003/03-0448/TR provides high performance and accuracy even in extreme heat situations.

The working principle of the M39003/03-0448/TR is based on the built-in electrochemical double layer. The anode consists of sintered tantalum material, and the oxide layer acts as the dielectric inside the capacitor. This chip capacitor is fit with three axial lead wires used to make electrical connection. The top side of the component is an electrically active surface while the other side is a ground plane.

The M39003/03-0448/TR uses a solid electrolyte as the cathode. The solid electrolyte is a mix of solid and liquid, such as manganese dioxide or electrolytic grade tantalum pentoxide. The electrolyte also functions to increase the stability of the capacitor. The electrolyte layer is highly resistive, which allows the capacitor to self-heal; if any damage to the dielectric occurs, it is automatically repaired by the electrolyte.

The M39003/03-0448/TR has an extremely low ESR (equivalent series resistance) and offers exceptional performance in AC and DC currents. It is an excellent choice for applications that require reliable performance in light of high temperatures.
