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.

2Metalized electrode
3Material to replace the shock wave
4Metal vapor air gap

8Breakdown channel
9Gaseous phase dielectric
10Area 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 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)
Q
What is the benefit of the Microwave pattern trimming technique?
This technique 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.
Q
How does the self-healing technology work in these capacitors?
During over-voltage or over-current conditions, the self-healing film isolates the breakdown area to prevent it from participating in the discharge process. This self-healing process achieves a density of at least 70% with only a minor capacitance loss of about 100pF.
Q
What safety mechanisms protect the capacitor from over-pressure?
The capacitor features triple protection (over-heat, over-load, and quick fusing). If internal pressure rises rapidly due to breakdown gas, it triggers the groove joint, activating disconnection or fusing to protect the system.
Q
What are the options for the capsulation technology?
Capsulation materials are selected based on industry applications. Options include eco-friendly thermoforming resin and inactive nitrogen gas (N2).
Q
How fast do the capacitors discharge?
The capacitors support both built-in and external discharge options, allowing for a fast discharge down to below 50V within 3 minutes.
Q
Are the capacitors fully tested before shipment?
Yes, 100% of the capacitors undergo strict testing standards, including winding core, loss, self-healing, high temperature tolerance, capacitance tolerance, and withstand voltage tests.
