Typical applications for TAAB685M035G are in areas where the highest possible capacitance to volume ratio is needed. It is a single anode capacitor, made from a solid electrolyte matrix of tantalum powder, with its leads welded to two aluminum foils. It is a device that is used in a wide variety of electronics capabilities from filtering and bypassing to coupling and timer circuits. It is highly reliable and often used in military and aerospace applications, with long product lifetimes.

The working principle of the TAAB685M035G is based on the dielectric that it utilizes. Tantalum capacitors use a layer of tantalum pentoxide (Ta₂O₅) as their dielectric material. This layer forms an insulating barrier between the two terminals of the capacitor, allowing a charge to accumulate at both terminals. The Ta₂O₅ is formed when electric current is passed through the tantalum electrodes to react with the electrolyte oxide solution. This reaction leads to the formation of a layer of Ta₂O₅ on the electrode surface.

The capacitance of a tantalum capacitor is dependent on its construction. Generally, capacitors are constructed using a top and bottom sheet of tantalum foil that have been etched with a pattern of electrical contacts which divide the two foils into small electrodes. The sheet of tantalum foil acts as the anode, and the etched pattern provides a number of individual capacitor plates or electrodes. The electrical capacity of the Tantalum capacitor is then determined by the size, arrangement, orientation and number of the etched plates.

In the case of the TAAB685M035G, it is made from a solid electrolyte matrix of tantalum powder. This allows for a high stationary capacitance with a very low ESR (Equivalent Series Resistance). The two aluminum foils are welded to the bottom plate and act as the cathode. The capacitor is then encapsulated in an epoxy case to protect it against moisture and contaminants. The epoxy case also helps to minimise stray losses, improving overall performance.

TAAB685M035G capacitors have a variety of applications in the electronics industry, ranging from filter and bypassing capacitors, to coupling and timer circuits. Its excellent capacitance to volume ratio makes it suitable for use in even the most strenuous electronic applications. Furthermore, its high reliability has seen it used in a number of military and aerospace applications for its long life product spans.
