Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of capacitor whose passive component is formed with tantalums with one side coated in conductive metal. M39003/09-0156 is a family of solid tantalum capacitors. These capacitors primarily come in two forms with two different mating techniques – an axial form and a radial form with either wire leads or MELF terminations. Although other forms are possible, M39003/09-0156 use these forms most commonly.

The M39003/09-0156 capacitors are suitable for a wide range of applications such as audio, automotive, computer and network applications, telecommunication systems, industrial control systems, medical instrumentation, consumer electronics and military applications. These are mainly used to store electrical charge, filter out unwanted frequencies or spike/voltage transients and to regulate line/load voltage. They are also used for power management, such as decoupling capacitors, energy storage applications and noise reduction.

The working principle of M39003/09-0156 is a result of the Faraday effect described by Michael Faraday back in 1831. In this, when an electrical field is applied to the plates of a capacitor, the charge stored across the curves will be proportional to the applied voltage. The capacitance of the device is proportional to the area of the plates and the gap between them.

M39003/09-0156 capacitors are made up of two metal oxide layers bonded to each other separated by an electrolyte material. Anode leads made with a thick layer of tantalum pentoxide are deposited on one side and conductive tantalum particles are then sputtered on the top. On the opposite side, a strip of conductive material is deposited which serves as the cathode lead. This results in an anode/cathode construction in which the anode lead will be attached to the metal case. The structure is then filled with an electrolyte material to complete the capacitor.

M39003/09-0156 capacitors offer high capacitance in a compact package with low-ESL values. Due to its construction, it can operate at higher temperatures and voltages than traditional aluminum electrolytic capacitors. Moreover, the fabrication process employed in the production of these capacitors makes them one of the most reliable and cost-effective capacitors on the market.
