Tantalum capacitors are submerged in an electrolyte and consist of an anode made of tantalum and an electrolyte consisting of manganese dioxide between two layers of solid electrical conductors. Electrons move around the intermetallic layer of the anode to form an oxide layer of capacitor’s tantallum. This oxide layer provides the necessary electrical insulation between the two parts of the capacitor.

M39006/09-8414 are a range of hermetic tantalum capacitors typically designed for temperatures up to 200°C (400°F). They are typcially used in military and extreme environment applications. Such capacitor components have dielectric oxide layers made from tantalum pentoxide (Ta2O5) and are dielectric dry between two aluminum electrodes with silver-nickel outer contacts.

These capacitors are used in military and aerospace applications such as in the missile guidance systems, radar and communication systems, navigation and fuel control systems. They are also suitable for space and extreme temperature applications in automotive, energy conversion, electronic control, and other industrial applications. The capacitors are created to withstand high temperatures and high vacuum levels that occur in applications such as these.

M39006/09-8414 tantalum capacitors offer a wide variety of capacitance, voltage, and size options for use in various types of circuit designs. These components are manufactured with cylindrical, rectangular, and spherical shapes, making them ideal for use in tight spaces. Tantalum capacitors have a very low dielectric absorption rate when compared to other capacitor types, and they are highly efficient in use. The inductance of these capacitors is very low due to their small form factor.

The working principle of these capacitors is based on the same properties that define other capacitors. When a voltage is applied across a pair of metal electrodes, an electric field is produced. This field holds the electrical charge that stores energy. The electrical conductor between the electrodes is called the dielectric and it is made of tantalum pentoxide in this case. The dielectric material has a smaller electrical conductive area and can therefore hold larger amounts of charge per unit area.

The dielectric also affects the characteristics of the capacitor. It can range from a few microns thick for a low-voltage capacitor up to a few millimeters thick for a higher voltage capacitor. It is this size that affects the capacitance. The longer the dielectric layer, the higher the capacitance value and the shorter the dielectric layer, the lower the capacitance value.

M39006/09-8414 tantalum capacitors are designed for use in applications that require high levels of capacitance combined with a very small form factor. The use of tantalum pentoxide as a dielectric material makes these capacitors extremely durable and reliable even in extremely hostile environments. They are also very efficient with a low electrical absorption rate.
