M39003/03-0183/TR

Tantalum Capacitors

Tantalum capacitors, specifically the M39003/03-0183/TR, are a form of electrochemical capacitor. They are constructed from two pieces of polarised metal, one of which is a tantalum ore. The two pieces are connected by an electrolyte, often a paste, gel, or oxide. This combination allows the capacitor to store a small amount of electric energy.

Application Field

The M39003/03-0183/TR is used in a variety of applications requiring smaller size, lighter weight and higher capacitance than what aluminium electrolyte capacitors offer. These applications include filtering, smoothing, bypassing and decoupling processes.

In addition, the M39003/03-0183/TR is popular in military and avionic applications due to its superior heat and vibration resistance, and its excellent reliability in temperature extremes. It is also used in high-end audio applications for its low equivalent series impedance (ESR) characteristics.

Working Principle

The M39003/03-0183/TR works on the basis of a Faradays Law of Electrolysis. This law states that when a voltage is applied between two electrodes submerged in an electrolyte, an electric current will flow between them, depositing electrons onto one electrode (the focusing anode) and removing electrons from the other electrode (the cathode). The result is the creation of a capacitance between the two electrodes.

The M39003/03-0183/TR works by taking advantage of this principle, utilizing the electrical energy stored in the electrolyte between the two plates. This energy is discharged when a voltage is applied across the capacitor, providing a short pulse of energy. As the voltage is removed, the capacitor will again be recharged with electrostatic energy.

Conclusion

The M39003/03-0183/TR is a highly reliable and versatile form of capacitor, and is suitable for a variety of applications requiring small form factor and superior thermal and vibration resistance. Its excellent reliability when subjected to extreme temperatures also makes it popular for military and avionic applications, while its low ESR characteristics make it a good choice for audio applications.
