Introduction to Tantalum Capacitors

Tantalum capacitors are the most widespread type of capacitor, boasting not just great performance but also long lifespan. This makes them the preferred choice of professionals, scientists, and electrical engineers.In brief, tantalum capacitors feature a tantalum anode (positive terminal) and a manganese dioxide cathode (negative terminal). The anode is covered by an insulating film called the dielectric layer, which prevents electric current from flowing between the anode and cathode. A rigid sealed construction and minimal dimensions make the caps highly sought-after for use in engineering fields where space is limited.Though small, the capacitance value of tantalum capacitors can be quite large, ranging from 0.01 µF to 4.7 mF. Electrolytic construction further improves its electrical characteristics (ESR and Leakage Current). Their high reliability and quality are also part of their appeal, making them market leaders for some applications.

199D225X9025A6A1E3 Application Field and Working Principle

The 199D225X9025A6A1E3 is a high-quality, reliable Tantalum Capacitor designed for use in demanding automotive and industrial environments. The capacitor features a square design that occupies minimal space and therefore perfectly fits in tight spaces. Its capacitance value is high enough to discharge and filter persistent current, reduce electrical noise, and filter power supply.The capacitor is a type of polarized capacitor that relies on an electrolytic solution to store electrical energy for a short period of time. Its working principle is the same as that of standard capacitors, with two metal plates – an anode (positive terminal) and cathode (negative terminal) – separated by an insulator (dielectric). The anode is made of tantalum and the cathode is made of manganese dioxide. The distance between the anode and cathode determines the capacitance value.When the capacitor is connected to a power source, an electric current passes through it. This process produces the storage of electrical energy which will serve in various situations, including power loss conservation. When the capacitor is disconnected from an external power source, power is drawn from the capacitor and released through the anode and cathode. This helps in protecting transient electronics, reducing electrical noise infiltration, and filtering power fluctuations.

Conclusion

The 199D225X9025A6A1E3 Tantalum Capacitor is a reliable and high-performance capacitor used in various automotive and industrial applications. Its working principle is the same as standard capacitors, taking advantage of polarized anode and cathode to store and discharge electrical energy. It is preferred for its robust construction, reliable performance, and minimal size.
