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.

- First, determine the total operating time (hrs).
- Next, determine the characteristic life (time till 63.2% failure).
- Next, determine the slope.
- Next, gather the formula from above = CR = e ^ -(t/n)^b.
- Finally, calculate the Capacitor Reliability.
- 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 =** ** ?
