Dear SI gurus,
 
Are there any industrial standards for derating of capacitors and resistors,
as well as inductors?
 
For example, a capacitor rated as 10V, what shall be the proper operating
voltage applied to this capacitor in term of reasonable voltage stress
ratio? As we know, the higher operating voltage will cause lower MTBF (Mean
Team Between Failure). Thus, lower the reliability of products. However,
using higher rated capacitor will increase cost of products. The same things
happen to resistors and inductors.
 
Talking about the damping resistors, how do we calculate the power consuming
on them so that we can calculation power stress ratio, operating power
divided by rated power?
 
 
 
Thank you for your helps in advance.
