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.

Frequently Asked Questions (FAQ)
What is the benefit of the Microwave Pattern Trimming Technique?
It uses a special corrugated trimming design that increases the effective spraying area by 20% on the side surface of the winding core. This strengthens the component and its connection points, enhancing the capacitor's high current resistance and overall stability.
How does the Self-Healing Technology protect the capacitor?
When over-voltage or over-current occurs, the self-healing film forms an insulation zone in the breakdown area to isolate it from the discharge process. This self-healing density can reach at least 70%, resulting in a minimal capacitance loss of about 100pf.
What filling materials are available for the new capsulation technology?
Depending on the specific industrial application, you can choose between eco-friendly thermoforming resin and inactive gas (N2) as filling options.
How does the Triple Protection Safety Design operate?
It features over-heat, over-load, and quick fusing protections. When internal pressure increases rapidly due to breakdown gas, it triggers the groove joint, activating disconnection or fusing. The same safety mechanism is triggered during high-current impulses.
What are the discharge options and discharge speeds?
Both built-in and external discharge options are available. The design ensures fast discharge to below 50V within 3 minutes.
What test standards do these capacitors undergo?
Every capacitor undergoes 100% testing, including: winding core test, loss test, self-healing test, high temperature tolerance test, capacitance tolerance test, and withstand voltage test.
