Wet tantalum capacitors have several advantages over solid tantalum, aluminum electrolytic, and ceramic capacitors. As with all other capacitors, these advantages lead to a very specific "sweet spot" or focused area of applications where the wet tantalum capacitor is the best and preferred choice.
The probability of failures of incorrectly installed solid tantalum capacitors has long been an issue in the aerospace community. G. J. Ewell from The Aerospace Corporation addressed this issue in 1984 by analyzing behavior of hermetically sealed metal case solid tantalum capacitors under reverse bias conditions [1].
Solid tantalum capacitors have a long history of proven performance in high-reliability military and space applications. But not all capacitors are created equal — even within the same class. As is the case with virtually all component technologies, materials matter.
10. Application Temperature (°C) As an example, if a tantalum capacitor is used without any derating, failure rates of 0.1 % to 1 % will occur. Tantalum capacitor manufacturers generally recommend that a minimum of 60 % voltage derating should be applied (if not specified differently in a product datasheet).
solid tantalum capacitors can survive substantial reverse bias without failure, this behavior significantly varies from manufacturer to manufacturer. Solid tantalum capacitors have been widely used in electronics, including military and aerospace applications, for more than 20 years. However, the processes of the reverse voltage bias ...

When AC current is applied to a solid tantalum capacitor, the resistance (ESR) that opposes the flow of current results in heat generation, according to the formula: (1) P = I2 x ESR. The power (P) dissipated in the capacitor results in an elevation of temperature. The allowable temperature rise of a capacitor due to power dissipation is ...

Note that a similar burn-in test for solid tantalum capacitors (Weibull grading test) is carried out typically at voltages in the range from 1.3VR to 1.52 VR. Considering that wet tantalum capacitors operate at conditions close to breakdown, increasing voltage to more than 1.1VR might be risky. For this reason, stress voltage is

A tantalum capacitor is one kind of electrolytic capacitor, which is a passive electrical device. It uses a capsule of spongy tantalum metal as an anode. An insulating layer of oxide covers the anode. The oxide layer further generates the dielectric. It is surrounded by a solid or non-solid electrolyte, which serves as a cathode.
Solid tantalum capacitors offer infinitely useful lifetimes and unparalleled volumetric efficiency, making them a smart choice for high-reliability applications including military, aerospace, and medical devices.

Solid tantalum capacitors recommend 50% derating in application, primarily due to transient and surge events that can be effectively overcome with appropriate circuit designs (e.g., characteristics including soft start, current limitation, circuit protection, etc.), while polymer capacitors generally only recommend 20% derating in application. ...
Capacitors consist of two conducting surfaces, usually metal plates, whose function is to conduct electricity. They are separated by an insulating material or dielectric. The dielectric used in all tantalum electrolytic capacitors is tantalum pentoxide. Tantalum pentoxide compound possesses high-dielectric strength and a high-dielectric constant.
Solid tantalum capacitors offer small size, low impedance, and low Q (to prevent loop stability problems). The downside of tantalum is limited voltage, typically 50V maximum, and a tendency for a small percentage of units to self-destruct when subjected to very high turn-on surge currents. AVX addresses the problem with their TPS line which ...
