Tantalum Capacitors

A tantalum capacitor is an electrolytic capacitor, a component of electronic circuits. It consists of a pellet of tantalum, which acts as an anode, covered by an insulating oxide layer, acting as the dielectric, surrounded by liquid or solid electrolyte acting as the cathode. The capacitance of a tantalum capacitor is much higher than other types of capacitors, allowing for a smaller component size for the same capacitance.

T491D155M050ZTZQ01

T491D155M050ZTZQ01 is a specific brand of tantalum capacitor. It has a capacity of 155 micro-farads and a voltage rating of 50 volts. It has a maximum operating temperature of 125 °C. This makes it well suited for use in a variety of industrial and commercial applications as well as medical, automotive and military/aerospace applications where high temperatures may be encountered.

Application Field

T491D155M050ZTZQ01 is often used in high frequency circuits due to its low equivalent series resistance (ESR) and high ripple current ratings. It is ideal for applications where voltage stability and high ripple currents are required. Examples of such applications include power supplies and motor drives. It can also be used for sample-and-hold circuits, filter networks and switched-mode power supplies.

Working Principle

T491D155M050ZTZQ01 works under the same principle as other types of electrolytic capacitors. The anode is in contact with a liquid or solid electrolyte, which serves as the cathode. When a voltage is applied to the capacitor, an electric field is created between the two which causes the electrolyte to become polarized. This polarization allows it to store a charge and form a capacitor. When the voltage is removed, the charge dissipates and the capacitor discharges.

T491D155M050ZTZQ01 tantalum capacitors are relatively low cost, high power and high frequency components suitable for a variety of applications in the electronic industry. With their great thermal and electrical characteristics, they can provide reliable performance in applications that require high power handling and are suitable for even the most demanding requirements.
