The spec for --R capacitors (such as X5R and X7R) is ±15%. The capacitance of parts with a code ending in V can actually decrease by as much as 82%! This probably explains why Y5V capacitors are not so popular. The following graphic gives you a good visual representation of how unstable Y5V and Z5U are compared to X5R and X7R.
2. The new standard should closely resemble the latest formats and style guides that are being used for ANSI/NEMA CP-1 2000 and IEEE Std. 18-2012. Users familiar with these standards would have greater ease in adoption and application of the new standard. 3. Chronology is important in a standard. New users should have a good understanding of
