Capacitor Lifespans
Capacitors naturally wear out after extended periods of use. Most capacitors are designed to operate for several thousand hours. Here is the projected lifespan for a typical capacitor, rated for 4,000 hours of operation at an average core temperature of 167 degrees Fahrenheit (75℃).
| Core temperature in degrees F (and ℃) | Projected lifespan in hours of operation |
| 221(105) | 500 |
| 203(95) | 1,000 |
| 185(85) | 2,000 |
| 167(75) | 4,000 |
| 149(65) | 8,000 |
| 131(55) | 16,000 |
| 113(45) | 32,000 |
