Tantalum Capacitors - M39003/01-8348/TR Application Field and Working Principle

Tantalum capacitors are increasingly popular in a variety of electronics applications due to their small size, long life, and high energy storage. The M39003/01-8348/TR, the latest tantalum capacitor from Vishay, is especially designed for use in military and aerospace applications, targeting extreme temperature environments. This capacitor offers both high reliability and high capacitance in a small package.

Technology Overview

Tantalum capacitors are electrolytic capacitors that use tantalum as their anode (positive electrode) material. In comparison to other types of electrolytic capacitors, tantalum capacitors have higher capacitance values and greater range of applications, due to their better performance in terms of smaller size, higher reliability, larger capacitor value range, and lower cost. The M39003/01-8348/TR incorporate an tantalum anode with an insoluble covering consisting of a resistant and chemically stable oxide layer. According to Vishay, the M39003/01-8348/TR series are rated with a capacitance of up to 22µF, with a wide operating temperature range of -55°C to +125°C.

Design Process

To design and manufacture computer-engraved tantalum capacitors, a very high level of accuracy is required. The fabrication process typically involves the use of an electron beam evaporator, a fine adjusting device, and a laser engraving machine. Generally, the capacitor die is finished to a tolerance of less than 0.05mm. After fabrication, the capacitor is subjected to a thorough electrical and reliability test based on the required technical documentation.

Application Fields

Due to their proven reliability and stability, M39003/01-8348/TR are suitable for a wide range of civilian and military applications, including navigation systems, avionics, power supplies, signal transmission, and telecom systems. Because they are engineered to withstand vibration and shock, they can be used in satellite systems, aircraft and military communication equipment, automobiles, and even missiles and space shuttles. The M39003/01-8348/TR offer small size and high reliability in extreme temperature applications.

Working Principle

The working principle of a M39003/01-8348/TR (tantalum capacitor) is fundamentally the same as any other electrolytic capacitor. In essence, this capacitor stores energy by creating an electrostatic field between two electrodes: the anode (positive) and the cathode (negative). The anode is made from tantalum, with a thin oxide layer to keep the charge from leaking. When an electrical current is applied, electrons flow out of the anode and into the cathode, creating a charge stored within the electric field. The dielectric material used in the M39003/01-8348/TR also plays an important role in its performance, as the oxide layer is tailored to provide maximum capacitance and protection from breakage.

Conclusion

The M39003/01-8348/TR tantalum capacitor series offers excellent performance in terms of high capacitance and reliability. This small package capacitor offers high performance for many extreme temperature applications. It has proven itself to be a reliable and durable component for use in many different applications. As a result, this type of capacitor is becoming increasingly popular among engineers and designers in a variety of fields.
