The lifespan of electronic components is affected by a variety of factors, including their type, operating conditions, quality and use environment.The following are typical life spans for various electronic components41:
| Component Types | Life span |
|---|---|
| Resistors | Decades or longer |
| Capacitors | Thousands to tens of thousands of hours |
| diode | Tens of thousands of hours or more |
| triode | Tens of thousands of hours or more |
| Integrated Circuits (ICs) | Tens of thousands to hundreds of thousands of hours |
| Variable resistors and variable capacitors | Thousands to tens of thousands of adjustments |
| Voltage regulator | Tens of thousands of hours or more |
| switch | Thousands to tens of thousands of switches |
It should be noted that these lifetimes are expected to be estimated under normal operating conditions.If the component operates under high temperature, high humidity, high voltage or other harsh environmental conditions, its lifespan may be greatly shortened.In addition, some components may have inherent aging phenomena, such as the electrolyte of the electrolytic capacitor will gradually fail over time, resulting in a decrease in the capacitance value.Therefore, when designing electronic systems, the life characteristics of components should be considered, and appropriate life evaluation and reliability design should be carried out.
