Subject: Quality Level
Message:
I am using RELEX to preform some reliability analysis and I was just wondering if someone could tell me how to determine the quality level for capacitors, resistors and diodes. For example for a ceramic chip capacitor you can select from D, C, S, R, P, M, L. What do these letters stand for? And how do I determine which one to use? Thanks!

Using MIL-HDBK-217 as the reference source, the quality level for commercial capacitors bought to a vendor part number would be 10. The response that you are referencing from Paul Jaworski has a typographical error. The commercial reliability factor referenced should be 10 not 1.0 as shown.
