Evans Capacitor Company manufactures energy dense hermetically sealed supercapacitors and ultracapacitors for mission critical applications
Tantalum powder is used in capacitors to allow for a very thin dielectric layer, providing high capacitance values in smaller case sizes. Vishay offers surface mount and through-hole tantalum capacitors for use in automotive, military, portable consumer, medical and many other applications.
Tantalum electrolytic capacitors exploit the tendency of tantalum to form a protective oxide surface layer, using tantalum powder, pressed into a pellet shape, as one "plate" of the capacitor, the oxide as the dielectric, and an electrolytic solution or conductive solid as the other "plate".

All custom sizes and finished parts can be produced quickly to the highest industry standards. Eagle Alloys can furnish bar, foil, sheet, plate, tubing and wire.
Capacitor grade tantalum powder provides about 25% of the market use of all tantalum shipments. Additional quantities related to capacitors are consumed by tantalum wire for the anode lead as well as for sintering tray assemblies and shielding components for the anode sintering furnaces.
A tantalum capacitor is a type of electrolytic capacitor, a component of electronic circuits.It typically consists of a pellet of tantalum metal as anode, covered by an insulating oxide layer that forms the dielectric, surrounded by conductive material as a cathode. Tantalum capacitors are the main use of the element tantalum. The tantalum capacitor distinguishes itself from other capacitors ...
Oct 23, 2015· The biggest risk with tantalum/nobium capacitors are surges and any reverse polarity at all. These risks can be largely mitigated by generously overrating their voltage. Doubling is a good start. AVX has some good white papers on this stuff. ... When/why (not) to use Tantalum capacitors. Pros, cons, alternatives
As systems have gotten smaller, capacitors have been a limiting factor since a certain size was needed to get the capacitance required, but that changed with the introduction and usage of tantalum capacitors.In this article we will look at some of the unique characteristics of tantalum capacitors and where their strengths and weaknesses are.

Tantalum capacitors are a specific form of electrolytic capacitor. Unlike the more familiar aluminium electrolytic capacitor, tantalum ones are much smaller and offer a very high level of capacitance for a given volume and weight.
Tantalum Capacitor Styles. For surface-mount applications, AVX manufactures two styles of tantalum capacitors, both of which incorporate an MnO 2-based cathode to take advantage of its self-healing characteristics and are shown in Figure 2. The molded style (top) is the more traditional configuration and utilizes a tantalum wire embedded in the ...

A HISTORY OF TANTALUM CAPACITORS. The history of solid tantalum capacitors started in the 1950s when the concept was invented by Bell Labs to provide small capacitors to accompany their transistors. The structure of a tantalum capacitor is sponge-like, with a very high surface area available for dielectric formation.
Tantalum Capacitor FA An Overview of Failure Analysis of Tantalum Capacitors Javaid Qazi, Kemet Electronics [email protected] Introduction A meaningful failure analysis of a capacitor (CAP) requires a thorough understanding of its construc-tion. Capacitors can be classified into different types based on their materials and construction ...
A typical tantalum capacitor is a chip capacitor and consists of tantalum powder pressed and sintered into a pellet as the anode of the capacitor, with the oxide layer of tantalum pentoxide as a dielectric, and a solid manganese dioxide electrolyte as the cathode.
