Tantalum Capacitors

Tantalum capacitors are artificial electronic components, composed of two electrodes sandwiched between a dielectric material. The M39003/09-2009/TR specification defines tantalum capacitors used in military and aerospace applications. These capacitors are used to store energy in direct current (DC) circuits. They are also known as electrolytic capacitors or “tantalum electrolytic capacitors.”

Application Field of M39003/09-2009/TR

Tantalum capacitors are used to store energy in direct current (DC) circuits where small size and high efficiency are important. Military-grade M39003/09-2009/TR tantalum capacitors are designed for usage in hostile environments, including conditions where temperature, pressure, and shock extremes may be encountered. They are suited for use in rough environments, with a range of voltages for different applications ranging from 25 to 1000V. They are often used in aerospace applications, for example in aircraft systems, and also in defense electronics.

Working Principle of M39003/09-2009/TR

The working principle of the M39003/09-2009/TR tantalum capacitor is based on the principle of electrostatics – the buildup of electric charges at two conductive electrodes separated by an insulating material called the dielectric. The capacitor works to store and discharge electrical energy. In the capacitor, electrical charges accumulate on the two metal electrodes separated by a dielectric material. The electrical charge accumulation or potential difference determines the capacitor’s capacitance, or the amount of electric charge stored in the device.

The M39003/09-2009/TR specification specifies capacitors required to have a wide range of operating temperature, with options available from -55 to +125 degrees Celsius. It also defines the parameters for internal resistance, leakage current, capacitance, dielectric strength, and maximum capacitance stability. Strict quality control measures are employed in order to meet the defined parameters, making these capacitors suitable for use in demanding environments.

Tantalum capacitors are known for their reliability, durability, and wide temperature range. They provide consistent performance even in extreme temperatures and can handle high-energy pulses. This makes them ideal for use in military and aerospace applications. As they are the most efficient type of capacitor, they are often preferred over other capacitors.

Conclusion

M39003/09-2009/TR tantalum capacitors are a specific type of electrolytic capacitor developed for military and aerospace applications. These capacitors are designed to offer electrical stability even in hostile environments and are capable of storing and discharging a wide range of energies. As reliable and dependable devices, they are capable of providing consistent performance over time.
