Tantalum Capacitors

Tantalum capacitors (also known as tantalum capacitors, Ta-capacitors, or tantalum electrolytic capacitors) are electrochemical capacitors that use a metal mass of tantalum as an anode, and an electrolytic solution as a cathode. The electrolyte acts as the dielectric between the two electrically conductive components, making tantalum capacitors some of the highest specific capacitance values at a given size and voltage rating.

T95R337K016CSSL Application Field and Working Principle

T95R337K016CSSL is a series of tantalum capacitors that offer outstanding performance in high temperature and high-reliability environments. The capacitors are widely used in consumer electronics, automotive equipment, communications devices, PCs, microwave ovens, power supplies and motor controllers. They also have a low ESR and a low ESL making them suitable for anti-noise filtering in switching power supplies and power amplifiers.

These capacitors are based on a two-terminal electrochemical device, which consists of two conductive surfaces, an anode and a cathode, separated by an electrolytic solution. The electrolyte serves as the a dielectric between the two conductive surfaces. When a voltage is applied across the electrodes of a capacitated device, a space charge is formed by the two conductive surfaces. This space charge is known as electric dipole, or polarization, and it is responsible for the capacitance of a given device. The value of the capacitance depends on the size of the anode and cathode surfaces, and the thickness of the dielectric. One of the advantages of this series of tantalum capacitors is that they offer a higher capacitance value than other types of capacitors – often up to 10 times. This makes them ideal for applications involving high frequencies.

In addition to offering a high capacitance value, these capacitors also have low equivalent series resistance (ESR) and low equivalent series inductance (ESL). That means they are not only able to filter and stabilize voltage effectively, but also suppress high frequency noise. Other advantages include high temperature rating, better mechanical strength, and longer life expectancy. These factors make them widely used in many types of electronic equipment and consumer products.

Tantalum capacitors have many features that make them suitable for a number of applications. Their high capacitance, low ESR and ESL, and excellent temperature ratings all combine to provide users with an effective and reliable solution. As such, they are often chosen over other types of capacitors for their performance and reliability in a range of applications.
