FAQ

Q:

What is the process for customizing products? How long does it typically take?

A:
The customization process consists of five steps: 1. Requirements communication (clarifying parameters, application scenarios, and batch requirements); 2. Solution design (the technical team develops and confirms the customization solution); 3. Sample making (producing samples and conducting performance testing); 4. Customer verification (customer confirms sample compliance); 5. Mass production. The standard customization cycle is 15-30 days, depending on product complexity and order volume. Urgent requests can be expedited upon negotiation.
Q:

Does your company support customized capacitor services?

A:
Yes. For the specific needs of high-end fields such as new energy and medical devices, we can provide customized R&D and production services, covering personalized adjustments to key parameters such as capacitance, voltage, size, and temperature rating. We can also assist customers in completing sample testing and mass production coordination.
Q:

What are your company's core products? In which fields are they mainly used?

A:
Our core product is metallized polypropylene film capacitors, with a focus on the CBB series. These products are widely used in various fields, including new energy (photovoltaic inverters, energy storage PCS, SVG, new energy vehicles), home appliances (air conditioners, refrigerators, washing machines), power tools (water pumps, cleaning machines), and medical devices (defibrillators), meeting the high reliability requirements of different scenarios.
