Tantalum capacitors are one type of capacitors that has a wide range of uses in electronics and other designs. Among these capacitors is the M39003/03-0478 which is a high voltage and axial leaded capacitor made from solid tantalum. It is a surface mount device with a capacitance of 470 nano Farads with a level 10 percent.

The application of the M39003/03-0478 is found largely in the fields of medical and defense equipments, telecommunications, and industrial production. It can also be applied to filters, resonators, and amplifiers in a wide array of digital and mixed-signal circuits.

This tantalum capacitor works through the use of a dielectric material between two conducting plates, known as the anode and the cathode. The dielectric material in the M39003/03-0478 is a tantalum oxide compound, commonly known as Ta2O5, which is a stable and highly insulating material. This material is carefully chosen for its low dielectric loss between the conducting plates at high frequencies and high voltage. This leads to a high capacitance value of 470 nano Farads, with only 10 percent variation in capacitance values.

The addition of the tantalum anode and the lead wires gives the capacitor a low impedance and allows for a resistance to ESR (Equivalent Series Resistance) of 15 ohms maximum. This prevents the capacitor from any damage due to the current, and also ensures that the capacitor is able to dissipate power effectively. The use of solid tantalum material also makes the capacitor corrosion resistant and temperature stable.

Lastly, the M39003/03-0478 is a fully enclosed capacitor and is rated for a voltage of 15 volts and a temperature range of -55 degree celsius to 125 degrees celsius. It also has a humidity sensitivity of 0.10 percent and a surge voltage of 250 Volts.

In conclusion, the M39003/03-0478 is a high voltage and axial leaded capacitor that is classified under the tantalum capacitor. It has a capacitance of 470 nano Farads with a level 10 percent. The application field of this capacitor is mainly in medical and defense equipments, telecommunications, as well as industrial production, and it is rated for a voltage of 15 volts and a temperature range of -55 degree celsius to 125 degrees celsius. The working principle of this capacitor is based on the use of a dielectric material between two conducting plates, and this dielectric material is usually a tantalum oxide compound, which gives it a low dielectric loss and a high capacitance value.
