Tantalum capacitors are essential passive components used to store electrical energy in electronic circuits. The M39003/09-2001 is an axial leaded form of the tantalum capacitor which has been designed for use in aerospace, military and commercial applications. While operating temperatures can range from -55°C to +125°C, this capacitor is not recommended for use in temperatures greater than +150°C.

The M39003/09-2001 offers excellent low and high temperature stability and performance, as well as commendable high peak current ratings, high burst current ratings, and impressive volumetric efficiency. These tantalum capacitors are also compatible with lead-free solder processes.

Applications: This type of capacitor is mainly used in military and aerospace applications, such as navigation systems, computer circuit boards, in-flight communication systems and communications modules in air navigation systems. The capacitor is also suitable for avionics power supply, discrete and hybrid circuits, high density PC-boards, and a variety of other military requirements.

Working Principle: The working principle behind the M39003/09-2001 tantalum capacitor is the same as other types of capacitors. This type of capacitor consists of two metal plates separated by an insulating material, which acts as the dielectric. When a voltage is applied to the capacitor, a charge builds up in each of the plates, and the capacitor stores energy in the form of an electrostatic field across the dielectric. The amount of energy the capacitor is able to store is proportional to the amount of charge stored in the two plates.

The M39003/09-2001 has a solid tantalum anode, with a thick manganese dioxide layer as the dielectric. The cathode is a porous coating of sintered tantalum powder that is placed directly onto the anode and electrically connected to the anode. This type of capacitor has excellent volumetric efficiency, as well as high capacitance and stability.

These tantalum capacitors are well-suited for a variety of applications due to their stability, volumetric efficiency, and high current ratings. The M39003/09-2001 is available in a variety of sizes and capacitance values, making it a versatile and reliable capacitor choice.
