PFC Capacitor for Power Quality Improvement - China Suppliers & Factory for Power Factor Correction Solutions
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.
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 are the advantages of the corrugated trimming design in Flair PFC capacitors?
The microwave corrugated trimming design increases the effective spraying area by 20% on the side surface of the winding core, strengthening the component and connection points, enhancing high current resistance, and ensuring long-term stability.
How does the self-healing technology function during a breakdown?
During over-voltage, over-current, or near end of life, an insulation area is formed in the breakdown area to isolate it from the discharge process. The capacitance loss is minimal (around 100pF), with self-healing density reaching at least 70%.
What triple safety protection features are integrated?
The capacitors feature triple protection against over-heat, over-load, and quick fusing. Internal pressure buildup from breakdown gas activates groove joint disconnection or fusing, and protects against high-current impulse.
How fast is the capacitor discharge capability?
Capacitors feature options for built-in or external discharge mechanisms, allowing fast discharge to below 50V within 3 minutes.
What encapsulation and filling materials are used?
Depending on industry application needs, encapsulation options include eco-friendly thermoforming resin and inactive nitrogen gas (N2).
What 100% quality tests are executed prior to delivery?
Every unit undergoes 100% testing across six criteria: winding core test, loss test, self-healing test, high temperature tolerance test, capacitance tolerance test, and withstand voltage test.
