Description :
Do your military capacitors exhibit “aging”? If so, how is it quantized?
Answer :
Tantalum: Tantalum capacitors do not exhibit aging.
Ceramic: All military BX & BR dielectrics (similar to commercial X7R) exhibit aging, which is a linear decline in capacitance with the log of time. Military BP dielectrics (similar to commercial C0G) do not exhibit aging, and remain stable with time. There is more detailed information on aging in our KnowledgeEdge application on KEMET.com.
