Tantalum capacitors are essential components for a wide range of products. These high-tech electronic components are made primarily from a combination of tantalum, one of the rarest elements on Earth, and an electrolyte. They offer several advantages over other types of capacitors, including larger size, higher capacitance and lower cost.

The M39003/01-7367/TR is an application specific tantalum capacitor, designed for space-constrained and high-temperature applications found in military and aerospace embedded systems. This device combines a solid tantalum construction with a manganese dioxide dielectric. With its flat rectangular shape, the device is ideal for surface mount applications that don’t have a lot of room to work with. The capacitor’s construction is made from multiple layers of solid tantalum and is welded together vertically. This creates a robust component that is able to withstand extreme temperatures and high vibration.

The working principle of this capacitor is based on the electrochemical behavior of its manganese dioxide dielectric layer. This layer acts as an insulator, preventing current flow between the two electronically charged tantalum plates. The capacitance of the device is determined by the size of the plates, the area of contact between them, and the permittivity of the manganese dioxide. As a voltage is applied across the capacitor, the electric field causes the manganese dioxide layers to polarize, allowing a charge to build up on the plates.

When the voltage reaches a certain level, the plates are saturated and the device begins to act as a resistor, limiting the current draw. As the voltage is further increased, the current draw decreases and eventually reaches a maximum limit. At this point, the manganese dioxide dielectric prevents any further current from flowing. The capacitor’s voltage rating and tolerance are set by testing to determine how much current the device can take without it becoming permanently damaged.

In addition to being used in military and aerospace applications, M39003/01-7367/TR is also suitable for use with power supplies, circuit protection, and AC and DC motors. Its high stability and wide temperature range makes it ideal for applications where long-term dependable performance is essential. The device also supports high ripple current and meets the MIL-PRF-39003/01-7367/TR military standard.

M39003/01-7367/TR tantalum capacitors offer a superior combination of ruggedness, reliability, and performance. Their unique construction and electrochemical behavior make them a perfect choice for high-temperature, space-constrained applications, while their wide temperature range and robust design ensures that they will continue to perform reliably for years to come.
