PFC Capacitors for Power Quality Improvement - High-Quality China Suppliers and Factory Options Available
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 an 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
2 Metalized electrode
3 Material to replace shock wave
4 Metal vapor air gap
5 Plasma area
6 Plasma area
7 Boundary layer
8 Breakdown channel
9 Gaseous phase dielectric
10 Replaced layer area
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 (FAQ)
What is the benefit of the Microwave pattern trimming technique?
This technique uses a special corrugated trimming design on the self-healing metalized film (thickness up to 8um/9um). It increases the effective spraying area by 20% on the side surface of the winding core, strengthening the connection points, enhancing current resistance, and ensuring capacitor stability.
How does the self-healing technology protect the capacitor?
If 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 causes a minor capacitance loss of about 100pf while maintaining a self-healing density of at least 70%.
What safety protection mechanisms are integrated into the design?
The capacitors feature triple protection: over-heat, over-load, and quick fusing. If internal air pressure rises rapidly due to breakdown gas under overload or heat, the groove joint, disconnection, or fusing is activated. High-current impulses trigger the same protection.
What options are available for capsulation and discharge?
For capsulation, eco-friendly thermoforming resin and inactive gas (N2) are available. For discharge, you can choose between built-in and external discharge options, which achieve fast discharge 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.
