Tantalum capacitors, or Ta capacitors, are electronic components, mainly used as energy storage devices for specialized applications, or as buffer reserves for high speed signal processing. The M39003/09-2066/TR is an example of such a component and is designed for military and aerospace applications. In this article, we will discuss the details of this component and its application field and working principle.

What is the M39003/09-2066/TR?

The M39003/09-2066/TR is a standard axially leaded tantalum capacitor which is capable of operating at temperatures from -55°C to +125°C. It is hermetically sealed and is designed for use in hostile environments such as those encountered in military and aerospace applications. The M39003/09-2066/TR is an ultra-low ESR (Equivalent Series Resistance) capacitor that can operate reliably up to 25 volts.

Application Field and Working Principle of the M39003/09-2066/TR

Tantalum capacitors are used in various types of electronic circuits to store energy and to filter out unwanted signals and noise. The M39003/09-2066/TR is particularly suited for use in high stability electronic application such as signal processing, power conditioning, voltage regulation and switching power supply circuits as its low ESR and high frequency performance enable it to filter out signals in fast changing environments. It is also used in spacecrafts and aircrafts where its low ESR and high temperature ratings are required.

On a basic level, a tantalum capacitor is composed of a tantalum anode and a manganese oxide cathode which is housed in a metallic case filled with an electrolyte solution. When a voltage is applied to the anode and cathode, a reaction occurs which results in the electrical charge being stored on the device. The amount of charge stored depends on the size and design of the capacitor as well as the resistance of the electrolyte solution and electrodes.

The M39003/09-2066/TR utilizes an anode composed of sintered tantalum, which is similar to other tantalum capacitors but features an innovative “hybrid” manganese oxide cathode. The combination of these materials provides an ultra-low ESR and enables the capacitor to operate at temperatures up to 125°C. The design also ensures a long shelf life as the manganese oxide is highly stable in the capacitor’s electrolyte solution.

The M39003/09-2066/TR is designed to reduce the capacitor installation cost and to enhance the reliability of components in hostile environments. The components are tested extensively in accordance with MIL-STD-202-F and are designed for use in extreme temperatures and vibration. The capacitor also complies with the RoHS and Pb-free initiatives, helping to ensure health and safety.
