around a Tantalum wire to make a Tantalum "slug". The term "slug" is used in the Tantalum capacitor manufactur-ing industry to refer to the Tantalum anode element. The riser wire will eventually become the anode connec-tion to the capacitor. Figure 3 shows an SEM picture show-ing how the particles have been bound together. Figure 3 SEM ...
Solid tantalum devices are well-suited for bulk energy storage due to their high and stable capacitance values and are widely used to hold up voltage rails during times of peak current demand. Here, two factors must be considered. The first is the total capacitance required to supply the required energy for the necessary time.
Tantalum has one of the highest melting and boiling points of all the chemical elements [3017 °C (5462 °F) and 5458 °C (9856 °F), respectively]. Its density (16.7 g/cm 3 ), is nearly half again as high as lead's (11.3 g/cm 3 ). Its thermal conductivity [35 W/ (M･K)] is quite low, only 20%-25% of molybdenum's or tungsten's, and less ...
The first solid Tantalum capacitors with a tantalum powder anode sintered in vacuum, an anodic oxide film of tantalum as the dielectric and a manganese dioxide (MnO 2) cathode were invented in the early 1950 s at the Bell Telephone Laboratories in the USA. 1 Similar to the liquid electrolyte cathodes in Wet Tantalum capacitors developed …

There are many thoughts on how to approach derating but one of our suppliers, AVX, has an excellent paper covering the reasons for different derating numbers called "Voltage Derating Rules for Solid Tantalum and Niobium Capacitors." The general rule for voltages is to derate a tantalum capacitor with an MnO2 electrolyte by 50% and a …
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. ... In 1993, Defense Electronics …

power supplies working cycle the short was applied. Another possible cause is when the capacitor is being used to supply the energy required to energize an inductor, for example a relay coil, a DC motor or a loud-speaker, particular if the inductor is turned on or off by SURGE IN SOLID TANTALUM CAPACITORS by John Gill AVX Ltd, Tantalum Division
The price hike and supply strain of tantalum intensified the need to look for a substitute for tantalum capacitors. The most commonly used capacitors other than tantalum capacitors are aluminum electrolytic capacitor, MLCCs, polymer solid aluminum capacitor, and in some instances, niobium capacitor.

In general, MLCCs have lower ESR than either solid tantalum or tantalum polymer capacitors of the same voltage rating and capacitance values. For a typical 47 µF, 6.3V 1206 capacitor, the maximum 100 kHz ESR levels would be something like this: Solid tantalum ~ 0.9 Ω. Tantalum polymer ~ 0.1 Ω. MLCC ~ 0.003 Ω.

11 min read. Tantalum is a transition metal element with the symbol Ta. It is a rare and dense metal known for its exceptional corrosion resistance and high melting point. It exists in the geology as a range of ores and is not present in the metallic state in nature. Tantalum is employed, either as a metal, in an alloy, or as one of its salts ...
Vishay can supply impedance vs. frequency information so the ESR and ESL can be used to determine the proper type capacitor for the ... Solid tantalum capacitors have no known wear-out mechanism( s). However, excessive voltage, current, and temperature can impact their long-term reliability. Reducing any of the mentioned stresses results in ...
Solid tantalum capacitors with manganese dioxide solid electrolyte (MnO2) — Industry standards call for a 50% voltage derating Tantalum capacitors with polymer electrolyte — The suggested voltage derating should be 10% (i.e. apply no more than 9V on a 10V rated capacitor) for capacitors with a voltage rating of 10 V or less.
