You need a transformer that can operate above 20 kHz, fit into tight enclosures, and still meet strict EMI and safety standards. Xinchangda’s full range of types of high frequency transformer delivers exactly that—whether you are designing medical equipment, renewable‑energy inverters, or high‑speed industrial drives.
1. Excessive cost – Traditional suppliers quote 30‑40% higher prices for low‑volume orders.
2. Unreliable quality – Inconsistent winding tolerances lead to 15‑20% failure rates in field tests.
3. Long lead times – Overseas factories often need 8‑12 weeks, delaying your product launch.
4. Regulatory uncertainty – Missing CE, FCC, or RoHS certifications can halt shipments to the U.S.
5. Limited customization – One‑size‑fits‑all designs rarely match your exact voltage, frequency, or footprint requirements.
Result: Project overruns, missed market windows, and reduced profit margins.
| Transformer Type | Frequency Range | Power Rating | Core Material | Typical Efficiency | Certifications |
|---|---|---|---|---|---|
| Ferrite‑Core HF | 20 kHz‑200 kHz | 5 W‑150 W | NiZn Ferrite | >92% | CE, FCC, RoHS |
| Air‑Core HF | 200 kHz‑1 MHz | 0.5 W‑30 W | Copper Windings, No Core | >95% | CE, FCC |
| Planar HF | 50 kHz‑500 kHz | 10 W‑200 W | PCB Substrate | >93% | CE, FCC, RoHS |

“Xinchangda cut our transformer cost by 28% and delivered the first batch in 6 days. The quality met all FCC and RoHS tests on the first attempt.” – John M., Procurement Manager, MedTech Corp.
“Their OEM design team turned a vague sketch into a production‑ready planar HF transformer in 48 hours. Project schedule stayed intact.” – Lisa K., VP of Engineering, GreenVolt Energy.
Compliance & Certifications: CE, FCC, RoHS, VDE, ISO 9001, CB, GS, SAA, HACCP/GMP, IPPC.
Ferrite‑core and planar HF transformers are preferred because they provide high efficiency (>92%), low EMI, and meet FDA‑Class II certification requirements. Xinchangda can supply custom‑wound units with ISO 13485 documentation.
Yes. Our ODM service starts at 100 pcs, and we offer a free CAD review plus a 30‑day money‑back guarantee if the prototype fails to meet specifications.
Standard production runs are completed in 5 days after artwork approval. Shipping to the U.S. via air freight adds 2‑3 days, total under 10 days from order confirmation.
All units are shipped with full test reports, including EMC, thermal, and safety certifications. We also provide a compliance dossier for your internal audits.
We offer a 12‑month limited warranty, free technical assistance via WhatsApp, email, and a dedicated account manager for the duration of the contract.
Limited‑time offer: First‑time customers receive a free sample of the exact transformer type you need, plus a 5% discount on orders over 5,000 pcs. Stock of high‑frequency cores is limited for Q2 2026.
