Tantalum capacitors are passive electronic components used to store electrical energy in a circuit. This type of component is composed of an anode, a capacitor dielectric, a cathode, an external resistor, and possibly a temperature compensating material. The M39003/01-8372 is a particular tantalum capacitor, manufactured by Vishay, which is commonly used for practical circuit purposes. The following article provides an overview of the M39003/01-8372 application field and working principle.

Application Field

The M39003/01-8372 is an axial tantalum capacitor especially suited for applications in military, space, power civilian, and medical fields. It is also used in high-density circuits, combining low impedance, a good temperature coefficient and small physical size. It has increased reliability due to its hermetically sealed construction, and is available with or without a screened terminal finish. Furthermore, this capacitor has a wide voltage range - it can operate with voltages between 10 and 63 Volts.

Moreover, this device has a relatively high capacitance maintenance throughout its entire working temperature range, -55 degrees Celsius to +105 degrees Celsius. High capacitance stability over a wide range of applied voltages and temperatures is what makes the M39003/01-8372 the ideal choice for application in harsh installations such as military equipment, space applications, and medical instruments.

Working Principle

The working principle of the M39003/01-8372 component is based on the combined effect of two of its layers. The first one is formed by a solid, porous tantalum anode covered by a coating made of a conductive polymer. The second layer is formed by the capacitor dielectric and cathode, which are kept under close contact between each other by the external resistor. This resistor serves to prevent the capacity of the component from changing drastically when an applied voltage is increased.

The capacitor dielectric can consist of different elements, from low permittivity materials such as polystyrene to high permittivity ones such as barium titanate. The cathode material can also be varied between metallic and non-metallic substances, such as manganese dioxide or silver-palladium.

When an electrical current is introduced to the component, the dielectric is polarized and an electric field appears between the anode and the cathode. This electric field is able to create an opposite electric charge on both electrodes, thus producing a capacitance effect. In other words, the electrical energy stored in the form of an electric field is proportional to the applied voltage.

Conclusion

The M39003/01-8372 is a tantalum capacitor designed for applications in military, space, power civilian, and medical fields. In addition to its good temperature coefficient and small physical size, the device has increased reliability due to its hermetically sealed construction and a wide voltage range. Its working principle consists in the combined effect of two layers: anode and cathode, separated by an external resistor. When an electrical current is introduced to the component, the dielectric is polarized and an electric field is created thus producing a capacitance effect.
