Tantalum capacitors are a type of electrolytic capacitor, typically constructed with a tantalum anode, anode oxide layer, cathode electrolyte, and an external casing for protection. The M39003/01-2872 is a series of tantalum capacitors focused on applications in military and aerospace systems. It is designed for superior performance, reliability, and temperature cycling, making it suitable for use in a variety of harsh environments.

As with other tantalum capacitors, the M39003/01-2872 has a cylindrical shape with an anode oxide layer inside and an electrolytic cathode. This oxide layer acts as the dielectric, enabling capacitances range from 10µF to 120µF at 6.3V to 50V, with voltage ranges from 4V to 25V, depending on the model. This series of capacitors offer excellent capacitance stability over voltage, temperature, and aging. In addition, they are highly resistant to vibration, shock, and radiation.

In terms of working principle, the M39003/01-2872 utilizes a chemically active barrier between the anode and cathode, allowing a current not to pass until the applied voltage reaches its rated breakdown voltage. The voltage applied to the capacitor causes a strong electric field to form between the anode and cathode, resulting in an ionic current. This ionic current results in a charge relay within the capacitor dielectric, the capacitor stores the energy, and the applied voltage will be discharged through the capacitor.

The capacitors can handle comparable levels of current as other forms of electrolytic capacitors, offering capacitance ranges up to 10,000µF at 25V. In terms of features, the M39003/01-2872 offers superior performance and reliability in extreme environmental conditions such as temperature cycling, vibration, shock, and radiation. In addition, they offer high temperature operating capabilities of up to +150°C and has an extended lifecycle of up to 10,000 hours depending on the model.

The M39003/01-2872 is a highly reliable and versatile series of tantalum capacitors for use in military and aerospace applications, offering superior performance and reliability for a range of harsh environmental conditions. With its extended lifecycle and temperature cycling capabilities, these capacitors prove to be an excellent choice for a variety of demanding applications.
