6 FAQs about [Failure of solid state capacitors]
What happens if a capacitor fails?
This failure can cause the enclosure to explode, smoke, ignite, harm other electrical components, or leak liquid or gas from inside the capacitor. Degradation failures may include increased leakage current, increased ESR, and decreased capacitance, although the definition of parameters and their limits vary among manufacturers *02, 03.
What is the failure mode of a capacitor?
Electromigration is one of failure mechanisms of semiconductor, but the failure mode can appear as a short, open, or characteristic degradation. Capacitors have several failure modes, the degree of which depends on the type of capacitor (Table 1).
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 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.
What happens if a solid electrolytic tantalum capacitor fails?
No ignition and burning tantalum were found in the Solid Electrolytic Tantalum capacitors that failed short. The black marks on the surface of these capacitors were the areas of the epoxy compound carbonized under the heat propagated from the fault sites in the dielectric at the breakdown event.
What is the degree of failure of a capacitor?
In general, the degree of failure is dependent on the degree of protection offered by user circuit design and process controls during both the manufacture of the capacitors and during their attachment to the circuit board. Those failures which have generated a lot of heat are readily observable by the user, the others are not.
