Testing and Quality Assurance After manufacturing, the capacitors undergo rigorous testing to ensure they meet performance and safety standards. 1. **Electrical Testing**: Capacitors are tested for capacitance, leakage current, and equivalent series resistance (ESR) to ensure they function as intended. 2. **Environmental Testing**: Capacitors are subjected to various environmental conditions, such as humidity, temperature extremes, and vibration, to assess their reliability in real-world applications. 3. **Reliability Testing**: Long-term reliability tests, such as life testing and accelerated aging tests, are conducted to predict the lifespan of the capacitors and identify potential failure modes. D. Packaging and Distribution Once testing is complete, capacitors are packaged and prepared for distribution. 1. **Packaging Techniques**: Proper packaging is essential to protect capacitors from physical damage and environmental factors during transportation. Anti-static materials and moisture barriers are commonly used. 2. **Distribution Channels**: Capacitors are distributed through various channels, including direct sales to manufacturers, electronic component distributors, and online platforms.
