6 FAQs about [Failure of high energy tantalum capacitors]
What is a tantalum capacitor failure mode?
Tantalum capacitor failure modes have been discussed both for the standard manganese dioxide cathode and the new conductive polymer (CP) type. For standard tantalum in the normal operation mode, an electrical breakdown can be stimulated by an increase of the electrical conductance in channel by an electrical pulse or voltage level.
Why are solid electrolytic tantalum capacitors declining in general applications?
The loss in volumetric efficiently and fear of ignition and burning tantalum failure mode, which now dominates online publications, resulted in decline in general applications of Solid Electrolytic Tantalum capacitors including the applications where high reliability and environmental stability of these capacitors are most needed.
Which polymer Talum capacitor has the lowest failure rate?
Polymer Tantalum capacitors manufactured with F-Tech have the lowest failure rate, which is decreasing with time of the accelerated testing (no wear-out) similar to that in Solid Electrolytic Tantalum capacitors. There is no ignition and burning tantalum in failed short SMD-type Solid Electrolytic Tantalum capacitors.
What causes a tantalum capacitor to breakdown?
For standard tantalum in the normal operation mode, an electrical breakdown can be stimulated by an increase of the electrical conductance in channel by an electrical pulse or voltage level. This leads to capacitor destruction followed by thermal breakdown.
Are tantalum capacitors unreliable?
Tantalum capacitors are not inherently unreliable. The reasons for their failure can be generally divided into two major categories: quality problems and circuit design problems.
What is a typical failure mode in solid electrolytic and polymer Talum capacitors?
The typical failure mode in Solid Electrolytic and Polymer Tantalum capacitors is low insulation resistance or a short.
