2) CYR20 and CYR30 capacitor styles were discontinued by AVX effective December 2004 due to low market demand and depletion of raw material stock for these styles. AVX was the sole source for this product.  Despite the lack of a source of supply, the NPSL will continue to list these styles for historical reference as to their acceptability for flight (e.g., new Projects may have access to residual inventory). See the AVX customer notification for further details.
