Long Life Aluminum Electrolytic Capacitors for Electronic Ballast and High Ripple Applications

Overview

The CD11GA series aluminum electrolytic capacitor is designed for circuits operating under high ripple current and elevated temperature conditions.
It is optimized for electronic ballast and energy-saving lamp applications where long service life and thermal endurance are critical.

Key Electrical and Reliability Features

• Long life design for high temperature environments
• Rated endurance: 130°C for 2000 hours
• Rated endurance: 105°C for 8000 hours
• High ripple current capability
• Suitable for continuous operation in lighting power circuits

Performance in Lighting Power Circuits

Electronic ballast and energy-saving lamp drivers operate with high ripple current and elevated internal temperatures.
Capacitors in these circuits must maintain capacitance stability and low ESR to ensure reliable power conversion and long operational lifetime.

Applications

• Electronic ballast systems
• Energy-saving lamp drivers
• High temperature power supply modules
• General high ripple current filtering

Design Considerations

• Verify ripple current rating relative to operating frequency
• Apply temperature derating for extended lifetime
• Ensure adequate ventilation and thermal layout
• Select voltage rating with sufficient operating margin
