Frequently Asked Questions (FAQ)

Q1: Are you a direct high frequency transformer manufacturer or a trading company?

A: We are a professional manufacturer with a 10,000㎡ facility in Dongguan. Unlike traders, we control the full supply chain from core selection to precision winding, providing factory-direct pricing and technical consistency for your B2B requirements.

Q2: Can you optimize leakage inductance for my high frequency transformer design?

A: Yes. A common pain point is high parasitic parameters. Our engineers optimize winding structures (such as sandwich winding or using triple-insulated wires) to minimize leakage inductance, ensuring your converter stays efficient with low EMI interference.

Q3: Does your high frequency transformer comply with UL and RoHS for global export?

A: Absolutely. As a global high frequency transformer supplier, our components are UL recognized (File E332338) and RoHS compliant. This ensures your end-products meet international safety standards and pass regulatory audits without delay.

Q4: I only have a schematic; can you provide design support for a custom EE14 component?

A: Yes. You only need to provide input/output voltage, frequency, and topology (e.g., Flyback or Buck-Boost). Our engineering team will calculate the turns ratio and inductance, providing a complete datasheet and prototype for your verification.

Q5: How does this high frequency transformer perform under extreme thermal stress?

A: We use high-permeability PC40/PC44 ferrite cores and Class B (130°C) or Class F (155°C) insulation. This solves the common buyer issue of magnetic saturation and overheating in high-density DC-DC converter environments.

Q6: What is the lead time for custom high frequency transformer samples?

A: Custom samples are typically completed within 3 to 7 working days. We maintain a steady stock of standard EE14 bobbins and cores, allowing us to respond quickly to your R&D schedule and reduce your time-to-market.

Q7: What payment methods do you support for international wholesale orders?

A: To facilitate secure international trade, we support T/T (Bank Transfer), PayPal, and Western Union. We provide formal commercial invoices and packing lists to ensure your financial compliance and transaction safety.

Q8: How do you help buyers reduce the Total Cost of Ownership (TCO) for transformers?

A: As your high frequency transformer supplier, we offer tiered pricing and low MOQs (500pcs). Our automated production lines reduce unit costs, while our DDP/DDU shipping options minimize your logistics complexity and hidden landing costs.
