Tantalum capacitors are electronic components made up of two tantalum electrodes with a tantalum electrolytic layer between them. The most common type of tantalum capacitor is the MnO2 tantalum capacitor, which uses manganese dioxide as the dielectric material. The MnO2 capacitors have good temperature coefficient, low leakage current, and excellent capacitive properties.

The M39003/01-3190 is a type of tantalum capacitor specifically designed for use in military, aerospace, and space-craft applications. This component is rated for voltage rating of 25V DC and its rated capacitance range is between 1µF and 470µF. This capacitor is housed in a rugged, hermetically sealed metal case and can operate up to 105°C ambient temperature. The chip-size package has an extended manganese dioxide capacitance-voltage curve, and is available with long-terminal leads.

The working principle of a tantalum capacitor is based on the capacitance effect. The two-terminal device stores electrical charge in an electrostatic field by using an insulating medium between its two electrodes. When a capacitor is connected to a DC power source, a reverse-biased voltage will cause a depletion region to form in the dielectric material. The depletion region will allow electric current to flow through the capacitor by creating a capacitance between the two electrodes.

The M39003/01-3190 tantalum capacitor offers a unique combination of high capacitance, long-term stability, superior electrical insulation, and effective EMI/RFI protection. This component is specifically designed for high-reliability and harsh environment applications, such as military/aerospace and space-craft applications. This capacitor is suitable for use in electronic power supplies, UPS systems, plasma display lighting, and radar systems.

Tantalum capacitors provide higher capacitance in smaller size and have superior electrical properties compared to ceramic capacitors. The voltage rating of the M39003/01-3190 is also higher than that of standard ceramic capacitors, which allows it to be used in high voltage applications. Additionally, the high temperature capability of this component makes it suitable for a wide range of high temperature and space-craft applications.

This capacitor also has a very long service life, and it can also withstand extreme temperatures over a wide range of environmental conditions. This makes it beneficial for military applications and high-reliability systems. The MnO2 type capacitance-voltage curve of this device offers extended capacitance and higher voltage ratings even with temperature change. The long-terminal leads provide extra mechanical strength and improved heat dissipation.

In conclusion, the M39003/01-3190 is a type of tantalum capacitor specifically designed for military, aerospace, and space-craft applications, due to its high capacitance rating, hermetically sealed metal case, long-term stability, and superior electrical properties. This capacitor is suitable for use in high voltage and high temperature applications, as well as in high-reliability and harsh environment applications due to its MnO2 type capacitance-voltage curve and long-terminal leads.
