Tantalum Capacitors

Tantalum capacitors are widely used in electronic equipment, including mobile phones, computers, and other communication devices. Evidence shows they have become increasingly popular in recent years due to their compatibility with printed wiring boards, low profile nature, and high volume of performance. This article will explore the application field and working principle of the M39003/01-8349/TR tantalum capacitor.

Application Field

The M39003/01-8349/TR tantalum capacitor is typically used in military, aerospace, medical, and industrial applications, due to its high reliability and stability. For instance, it is used as a power filter in avionics and radar systems due to its ability to withstand high temperatures and vibrations, providing reliable operation even when exposed to extreme environmental conditions.

Another application where the M39003/01-8349/TR is used is in medical devices, which require precise voltage regulation for safe and effective patient care. The capacitor is also used in industrial and military applications, where its robust construction and high reliability make it suitable for harsh environments. The capacitor is also used in communications and telecom equipment, as its robust capacitance and low profile make it ideal for high-volume production.

Working Principle

Tantalum capacitors work by storing electrical energy in a dielectric medium that oxidizes to form a conductive path for the electronic current. This process is known as dielectric hysteresis. In the case of the M39003/01-8349/TR, a tantalum foil is used as the dielectric medium, and the dielectric hysteresis is induced by applying a voltage across the capacitor. The applied voltage causes a chemical reaction between the tantalum foil and the electrolytic solution, which causes the lamination of the tantalum to expand and increase the dielectric strength.

The M39003/01-8349/TR also features a small Φ tolerance, which means that when a specified voltage is applied to it, the capacitance of the component will not vary significantly. This is due to its superior temperature stability, which enables it to maintain the capacitance even in hot and cold temperatures.

The M39003/01-8349/TR is also manufactured with an anode overvoltage protection feature, which prevents damage to the capacitor if reverse voltage is applied. This ensures maximum reliability and durability, and allows the capacitor to function even when safely overstressed.

Conclusion

The M39003/01-8349/TR is a robust and high-quality tantalum capacitor, offering peak performance and reliable operation even when exposed to extreme environmental conditions. The capacitor is suitable for military, aerospace, medical, and industrial applications, due to its high temperature and vibration resistance, capacitance, and anode overvoltage protection feature. The dielectric hysteresis induced by the voltage applied to the capacitor causes the tantalum foil to expand, forming a conductive path for the electronic current.
