Preventative Measures

To avoid future capacitor failures, consider the following preventative measures:

Use High-Quality Capacitors: Always use capacitors from reputable manufacturers to ensure high-quality and long-lasting performance.

Proper Circuit Design: Ensure that your circuit is designed to handle the expected voltage and current without stressing the capacitors too much.

Heat Management: Implement adequate cooling measures (such as heatsinks or fans) to prevent excessive heat buildup around sensitive components like capacitors.

Regular Maintenance: Periodically check the condition of capacitors in older systems to catch early signs of degradation.
