PFC Capacitor for Power Quality Improvement - China Suppliers & Factory for High-Performance Capacitors
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 strengthened. 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 possible 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 occurred 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
Q: What is the advantage of the Microwave pattern trimming technique in Flair PFC capacitors?
It uses a special corrugated trimming design on a self-healing metalized film plated with metal components up to 8um/9um. This design increases the effective spraying area by 20% on the side surface of the winding core, strengthening connection points, enhancing current resistance, and ensuring overall stability.
Q: How does the self-healing technology work during a breakdown?
When over-voltage or over-current occurs, the self-healing film forms an insulation area around the breakdown zone, preventing it from participating in the discharge process. This self-healing process results in a minimal capacitance loss of about 100pf and can achieve a self-healing density of at least 70%.
Q: What filling options are available for the new capsulation technology?
Depending on the specific requirements of the applied industries, filling options include eco-friendly thermoforming resin or inactive gas (N2).
Q: What safety protection designs are integrated into these capacitors?
The capacitors feature triple protection against over-heat, over-load, and quick fusing. If internal pressure rises rapidly due to breakdown gas, a groove joint is triggered to activate disconnection or fusing. The same protection mechanism is triggered for high-current impulses.
Q: What are the discharge specifications of the capacitors?
The capacitors support both built-in and external discharge options, providing fast discharge to below 50V within 3 minutes.
Q: What quality and testing standards do the 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.
