Tantalum capacitors offer several advantages over other types of capacitors, such as long shelf life, low ESR, and low tolerance. In this article, we will be discussing the application field and working principle of the M39003/01-3084/TR tantalum capacitor.

Applications:

M39003/01-3084/TR enables designers to implement the most power dense solutions available in the market for military, aerospace, and medical applications. It is used in various kinds of avionics and defense systems such as aircraft or missiles, computers, GPS navigation, and medical devices. It is also used in high-end audio components, robust industrial equipment, and automotive devices.

The M39003/01-3084/TR has excellent efficiency and power density when compared to other types of capacitors. It has an excellent ripple current rating and low equivalent-series resistance (ESR) for maximum load current and excellent voltage regulation. Due to its small form factor, the M39003/01-3084/TR can be used in the most space-constrained applications. The reliable and low leakage performance of the M39003/01-3084/TR enable it to be used in high-temperature and radiation-intensive environment.

Working Principle:

The M39003/01-3084/TR use anodes constructed from tantalum metal powder families which are sintered to form slugs with a high specific surface area. The capacitance of the M39003/01-3084/TR is determined by the surface area, the thickness of the oxide that forms the dielectric, and the applied voltage. The anodes are then processed with a proprietary MnO2-based electrolyte and are hermetically sealed inside an aluminium case.The M39003/01-3084/TR capacitors are then filled with an inorganic electrolyte.

The anode-cathode structure of the M39003/01-3084/TR is the same as other standard electrolytic capacitors, except for the electrolyte material. When the capacitor is used, the applied voltage drives the anode ions to the cathode, creating an electrolyte layer, as shown in the schematic diagram. This creates a double layer capacitance structure which gives the M39003/01-3084/TR capacitor its high capacitance and low leakage current. The low tolerance and excellent reliability are the result of the precision machined anode.

Conclusion:

The M39003/01-3084/TR is a high-performance tantalum capacitor designed for use in demanding military, aerospace, and medical applications. Its low equivalent series resistance, low tolerance, and high capacitance make it ideal for power-dense applications. Its hermetically sealed aluminum case and inorganic electrolyte ensure reliable performance in high-temperature and radiation-intensive environments. The M39003/01-3084/TR is an excellent choice for designers and engineers looking for the highest performance in small packages.
