Do Tantalum Capacitors Age?
General Characteristics Tantalum Capacitors Are Very Stable over Time and Their Capacitance Doesn't Change with Age Significantly, Especially When Compared to...
How long do tantalum capacitors last?
Whilst MLCCs are susceptible to aging, polymer tantalums achieve long-term stability over an operational lifetime of 20 years. This longevity also makes polymer tantalums a viable alternative to aluminium electrolytic capacitors which can dry-out in use and may require re-forming after a shelf-life of 2 years or less.
Do tantalum caps go bad?
Any cap can fail, any component can fail. There are a lot a factors. Tantalum caps have proven to be very reliable, but there are ways to abuse them. Designers can run them over their ratings, or use them in a manner not appropriate, you can buy cheap caps, and you can install them backwards.
