PFC Capacitor For Improving Power Quality
Capacitor technology
1.Microwave pattern trimming technique
Flair PFC capacitor applied for a special self-healing metalized film which is plated special metal components with thickness up to 8um/9um. A special corrugated trimming design is adopted to the self-healing metalized film. The special design make the effective spraying area increase by 20% in side surface of winding core. So that the component and its connection points are strengened. Furthermore, it enhance the capacitors’ high current resistance and ensure the stability of the capacitors.
2.Self-healing technology
When over-voltage,over-current occurs, or near the end of life, it’s possbile to break down the capacitor. The self-healing film will form a insulation area in the breakdown area that will not participate in the discharge process. The self-healing will cause a capacitance loss about 100pf. And the self-healing density can reach at least 70%.
3.The new capsulation technology
The filling materials will be selected according to the applied industries. Eco-friendly thermoforming resin and inactive gas (N2) available for options.

| 1. Dielectric | 6. Plasma area |
| 2. Metalized electrode | 7. The boundary layer between Gaseous phase dielectric and plasmas |
| 3. Material to replace the shock wave | 8. Breakdown channel |
| 4. Metal vapor air gap | 9. Gaseous phase dielectric |
| 5. Plasma area | 10. An area that replaces the metallized and dielectric layers |
4.Safety Protection design
Triple protection: Over-heat, over-load, quick fusing
When it came to over-heat, over-load or near the end of life, there will be mass breakdown gas occured inside of the capacitor, the inside air pressure will increased very fast, thus will trigger the groove joint, disconnection or fusing will be activated, same protection being triggered for high-current impulse.
5.Discharge
Built-in discharge and external discharge for options. Fast discharge below 50V in 3 minutes.
6.Protection level IP20 for touchable terminals
