AVX's TCB is a COTS-Plus upscreened version of the TCR professional conductive polymer multianode series designed for use in demanding industrial applications requiring very low ESR with stable, high-frequency CAP retention and longer life performance, such as high-power DC/DC converters employed in telecommunications, industrial, and avionics. The series exhibits improved basic reliability of 0.5%/1,000 hours at +85°C. Capacitors are designed to withstand biased humidity testing at +85°C/85% R.H. for at least 500 hours and rated for operation up to +125°C. Additional surge screening at -55°C and +85°C and SnPb plating optional upon request.
