Important Information On Application
- Use DC capacitors with correct polarity.
- Use capacitors within rated voltage.
- Avoid rapid charge and discharge for general-purpose capacitors.
- Storage recommendations: Ambient temperature 5~35, humidity <75%RH. Storage life 12 months. Recharge required for storage >12 months. Discard after 3 years.
- Apply ripple current within rated limits.
- Ambient temperature significantly affects life.
- Avoid applying excessive force to lead wires.
- Be cautious of heat resistance during soldering.
- Ensure PC board hole pitch matches lead spacing.
- Cleaning after soldering: Avoid halogenated solvents. Dry with hot air if cleaned.
- Avoid halogen-containing adhesives, coating materials, and PCBs.
