Tantalum Capacitors

Tantalum capacitors are versatile and reliable components used in a wide variety of applications. They are distinguished by their ability to offer high capacitance values at a relatively low weight and small size. They can be used for high voltage and temperature applications, and offer excellent reliability and performance. The M39003/03-0455/TR is a tantalum capacitor from the MIL-PRF-39003/12 family. This part is an axial leaded, polarised capacitor offering excellent performance in a wide range of applications. This model is commonly used in military, aerospace and other demanding applications.

Application Field

Tantalum capacitors are used in a variety of applications, most notably military, aerospace and high-speed/high-temperature applications. In military and aerospace applications, tantalum capacitors offer superior performance in extreme and hazardous environments. High-speed/high-temperature applications require higher capacitance, reliability and performance, and the M39003/03-0455/TR is a great choice for these applications. Tantalum capacitors also have the ability to withstand higher operating temperatures and voltages than other types of capacitors. This makes them ideal for applications in harsh environments, such as welding and power supply applications. They also offer the advantage of low self-inductance and excellent frequency characteristics, making them suitable for high-speed signal processing applications.

Working Principle

The M39003/03-0455/TR is a tantalum electrolytic capacitor, consisting of a tantalum anode and cathode, separated by an electrolyte. The anode is made of an electrochemically active metal oxide, and the cathode is a thin electrically conductive film. When connected to an external power source, a current begins to flow between the two electrodes. This current causes a charge to build up on the capacitor, which is then discharged whenever the external power source is removed. Tantalum capacitors are known for their excellent frequency characteristics, allowing them to store electrical energy over a wide range of frequencies. They also have low equivalent series resistance (ESR), making them ideal for high-speed signal processing applications.The M39003/03-0455/TR has a wide temperature range (from -55°C to +125°C), making it suitable for various applications. It also has a maximum operating voltage of 10V, making it suitable for applications with higher power requirements.

Conclusion

Tantalum capacitors are versatile and reliable components which offer excellent performance in a range of applications. The M39003/03-0455/TR from the MIL-PRF-39003/12 family is a good example of a tantalum capacitor, offering a wide temperature range, high capacitance values, and excellent reliability and performance. They are commonly used in military, aerospace and other demanding applications where higher operating temperatures and voltages are necessary. They also offer the advantage of low self-inductance and excellent frequency characteristics, making them suitable for high-speed signal processing applications.
