Enter the total operating time (hrs), the characteristic life (time till 63.2% failure), and the slope into the Capacitor Reliability Calculator. The calculator will evaluate the Capacitor Reliability. 

Capacitor Reliability Formula

The following formula is used to calculate the Capacitor Reliability. 

CR = e^{-(t/n)}*b

Variables:

  • CR is the Capacitor Reliability ( )
  • t is the total operating time (hrs) 
  • n is the characteristic life (time till 63.2% failure) 
  • b is the slope 

How to Calculate Capacitor Reliability?

The following steps outline how to calculate the Capacitor Reliability.

  1. First, determine the total operating time (hrs).
  2. Next, determine the characteristic life (time till 63.2% failure). 
  3. Next, determine the slope. 
  4. Next, gather the formula from above = CR = e ^ -(t/n)^b.
  5. Finally, calculate the Capacitor Reliability.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

total operating time (hrs) = 3

characteristic life (time till 63.2% failure) = 5

slope = 7

CR = e ^ -(t/n)^b =  ?
