Tantalum capacitors are unsurpassed in stability, frequency response, and reliability. The construction of this particular capacitor, the M39003/01-2259, takes advantage of these strengths to reach higher levels of performance. It combines tantalum powder with two anodized layers, achieving an extremely low ESR (equivalent series resistance) and providing robust temperature stability. Furthermore, the material of the M39003/01-2259 capacitor is slightly conductive which prevents arcing, reducing the possibility of catastrophic failure.

The distinct characteristics of tantalum capacitors makes them a popular choice for specific applications. The low ESR of the M39003/01-2259, for example, makes this series suitable for a wide range of high frequency applications, as well as for use in low impedance circuits. Its wide temperature range also makes it an ideal choice for equipment operating in extreme environments. Specifically, numerous audio equipment manufacturers use the M39003/01-2259 for signal filtering and energy storage. Similarly, this series is often used in the military and aerospace industries due to its extreme reliability, rugged construction, and tolerance of high-voltage stresses.

The working principle of the M39003/01-2259 series involves a two-stage anodizing process that provides a non-conductive barrier between the tantalum powder and the anode. This barrier acts as an insulator, which keeps the electric current away from the anode and maintains a mechanical structure that is strong enough to withstand high-voltage shocks. The electrode is then connected to a terminal placed outside the capacitor, and electricity flows between it and the electrodes when an alternating current is applied. As the current passes through the device, it creates a dielectric energy stored in the anode. The dielectric energy provides the insulation necessary for reliable performance.

In summary, the M39003/01-2259 tantalum capacitor is a unique product due to its high level of performance, temperature stability and low equivalent series resistance. It is highly suitable for a variety of applications, particularly in audio applications and in the military and aerospace industries. Its reliable structure and operation are made possible by a two-stage anodizing process which provides a barrier between the anode and the tantalum powder, enabling the dielectric energy necessary for its stable operation to be generated.
