Tantalum Capacitors: M39003/09-0006/TR Application Field and Working Principle

Tantalum capacitors, also known as tantalum electrolytic capacitors, are special electronic components which are often used in industrial operations, military applications and even consumer products. The M39003/09-0006/TR versions of these Tantalum capacitors are a highly-refined version suitable for use in sensitive environments and applications.

Both the field of application and the working principle of the M39003/09-0006/TR Tantalum capacitors need to be understood in order to get the most out of them.

Field of Application

The M39003/09-0006/TR Tantalum capacitors are not marketed as general-purpose electronic parts. They are rather geared towards applications in which exceptionally high levels of accuracy are required. This is mainly the case for military and space applications. But they are also becoming increasingly adopted by industries in the general public space, such as medical technology, where accuracy is key to the product’s success.

The M39003/09-0006/TR versions of the tantalum capacitors have the advantage of a lower equivalent series resistance to more effectively achieve higher levels of accuracy than their civilian counterparts. They are also capable of operating over a wide range of temperatures and supply voltages, which make them especially suitable for powering mission-critical components in sensitive operating environments.

Working Principle

Tantalum capacitors work on the same basic principle as other capacitors, but the M39003/09-0006/TR versions have certain refinements which impart them with superior performance. The core of the capacitor is an oxide-coated tantalum pentoxide electrode which is capable of storing a charge. This is encased in an epoxy-coated aluminum can which has a tapering body and a pair of flat end caps.

The M39003/09-0006/TR capacitors are designed to operate in a three-wire circuit. Two of the wires are connected to the end caps and the third is connected to the can, providing a negative terminal for the capacitor. The negative terminal acts as an electrode on which the stored charge is stored and modulated. The positive terminal is connected to the body of the can and allows for a charged current to be passed to the capacitors.

The capacitor is then able to modulate the current and store it on the oxide-coated tantalum pentoxide electrode. Other features of the M39003/09-0006/TR capacitors which enhance their accuracy include their narrow voltage tolerances, high pulse capacitance, long-term reliability, and excellent thermal stability.

Conclusion

The M39003/09-0006/TR versions of Tantalum capacitors are specifically tailored to Military, Space and Mission Critical applications. This is because they are designed for especially high levels of accuracy, stability and long-term reliability. They therefore require specific circuitry in order to benefit from their full range of features. Their working principals are also slightly more complex than other types of capacitors, as they rely on the oxide-covered tantalum pentoxide electrode to modulate the current passing through them.
