Product Detail

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 (FAQ)

Q1: What is the benefit of the Microwave Pattern Trimming Technique?

This special corrugated trimming design increases the effective spraying area on the side surface of the winding core by 20%. This strengthens the component connection points, enhances the capacitors' high current resistance, and ensures overall stability.

Q2: How does the self-healing technology protect the capacitor?

When over-voltage, over-current, or near-end-of-life breakdown occurs, the film forms an insulation zone in the breakdown area to isolate it from discharging. This process causes a minimal capacitance loss of about 100pf and achieves a self-healing density of at least 70%.

Q3: What materials are used for the capsulation technology?

The filling materials are selected based on industry applications, offering options of eco-friendly thermoforming resin or inactive nitrogen gas (N2).

Q4: How does the safety protection design work under fault conditions?

It features triple protection (over-heat, over-load, and quick fusing). High temperatures or overloads cause internal pressure to rise rapidly from breakdown gases, triggering the groove joint to disconnect or activate the fuse.

Q5: What are the discharge capabilities of these capacitors?

Options include both built-in and external discharge configurations, enabling fast discharge to levels below 50V within 3 minutes.

Q6: What quality and testing standards do the capacitors undergo?

100% of the capacitors undergo strict testing, including Winding core test, Loss test, Self-healing test, High temperature tolerance test, Capacitance tolerance test, and Withstand voltage test.
