Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor. It is composed of two conducting surfaces separated by an electrolyte containing a high concentration of tantalum ions in solution. The main advantage of tantalum capacitors is their relatively small size and high capacitance when compared to other capacitor types. Other benefits include their low cost, long life cycle, and excellent stability.

TM3D157K6R3CBA Application Field and Working Principle

The TM3D157K6R3CBA series of tantalum capacitors are designed for use in advanced analog and digital/mixed signal circuitry, as well as in critical timing/clocking components. The series consists of several sizes in two lead styles, with capacitance values ranging from 47μF to 220μF (±20%).

The working principle of a tantalum capacitor is based on the movement of ions from one electrode to another through an electrolyte, forming a charge "bridge" between the two electrodes. This creates an electric field across the electrolyte, which stores an electric charge. The capacitance of the capacitor is determined by the ratio of the area of the electrode to the distance between them.

The tantalum capacitors have two poles, one of which is an anode formed from a sintered tantalum rod, and the other a cathode. When voltage is applied, ions from the anode flow into the liquid electrolyte, forming a salt bridge. The electrolyte acts as an insulator, allowing electrons to flow in one direction, charging the capacitor. The charge remains on the capacitor until the voltage is removed.

The TM3D157K6R3CBA series of tantalum capacitors feature a unique design combining low equivalent series resistance (ESR) and low leakage current. The series offers an extended operating temperature range from −55°C to 125°C, ensuring reliable performance.
