Introduction to Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor, a passive electronic component which consists of two conducting plates separated by a dielectric material and coated in an electrolyte solution, in a capacitor\'s case, the dielectric material is a disk made of tantalum, a metal element found in the periodic table.

Due to the high capacity of tantalum compared to similar type components, it is often desired as a material in electrical circuits. This makes them attractive for many applications where low-profile components are desired, such as in laptop computers, cell phones, and other portable devices. Furthermore, their stable capacitance under high temperatures, small size, large capacity and ease of use has increased their utility in many electronics.

Application Field and Working Principle Of TPSV687M006R0040

TPSV687M006R0040 is a 2.5V, 3.4V nominal, low-ESR, low-profile, 5mm x 6.8mm, chip tantalum capacitor. It is considered one of the most reliable types of tantalum capacitor available. It has a wide range of application fields, such as peripheral type applications as used in notebook also as powerful applications, like graphic systems and power supplies.

TPSV687M006R0040 operates in undervoltage lockout and reverse-voltage workload to guard against fault conditions, such as short circuit, overvoltage and reversed polarity.

Its working principle is like other capacitors; it uses the principle of electrostatic field and the obtained charge to store energy. The two terminals of the capacitor are called the anode and cathode. When the capacitor is connected across a voltage source, a potential difference is established between the anode and cathode, resulting in an electric field. This is known as charging the capacitor. The capacitor stores the charge by depositing a layer of electric charge onto its plates. When the capacitor is removed from the voltage source, the stored energy can be discharged in the form of an electric current through any load connected across the capacitor.

Conclusion

TPSV687M006R0040 is a high-quality, low-ESR, low-profile tantalum capacitor, used for a number of applications. It offers many advantages over other types of capacitors, such as its small size, high capacity and stable capacitance under high temperatures. It functions using the principle of electric field, using the potential difference between its anode and cathode to store electric charge. All these characteristics make it a desirable component in many electrical and electronics systems.
