Aluminum electrolytic capacitors are widely used in power supplies, LED drivers, industrial equipment, and consumer electronics. However, the life of a WGD LRH Long Life Aluminum Electrolytic Capacitor can still be affected by operating temperature, voltage stress, storage conditions.

Here are three important factors that can help extend capacitor lifetime.

1. Reduce Operating Temperature

High temperature is one of the main factors that reduces aluminum electrolytic capacitor lifetime.

Excessive heat accelerates electrolyte evaporation, causing capacitance loss and increased ESR.

To extend capacitor life:

• Improve ventilation and airflow 

• Keep capacitors away from heat sources 

• Select suitable temperature ratings, such as 105°C capacitors 

A lower operating temperature helps ensure stable performance for a WGD LRH Long Life Aluminum Electrolytic Capacitor.

2. Avoid Long-Term Storage

Long-term storage may affect the oxide layer inside aluminum electrolytic capacitors, which can increase leakage current after reactivation.

For better reliability:

• Store capacitors in a dry environment 

• Avoid extended storage periods 

• Perform voltage reforming when necessary 

3. Keep Voltage Within the Rated Range

Operating beyond the rated voltage can damage the internal dielectric layer and shorten capacitor lifetime.

It is recommended to:

• Keep sufficient voltage margin 

• Avoid voltage spikes during startup 

• Select suitable voltage ratings according to application requirements 

Conclusion

Proper application is essential to maximize the lifetime of aluminum electrolytic capacitors.

By controlling temperature, voltage, storage conditions, engineers can improve system reliability.
