1. The EPC Mobile Phone Charger High-Frequency Transformer by haoer factory adopts a flat ferrite core, which can meet the requirements of high power and ultra-thin volume at the same time, and can also adapt to the temperature rise requirements of switching power supplies. Its structure is reasonable, and compared with EPD type transformers, it has improved online package space. At the same time, its EMI performance, leakage inductance, radiation and other parameters are better than EFD type transformers, and its other performance is close to EE type and EC type transformers.
2. EPC high-frequency transformer performance characteristics: low thermal resistance, low attenuation, high power, wide operating frequency, light weight, easy surface mounting, good shielding effect.
3. EPC high-frequency transformers are commonly used in DC-DC converters, drive transformers, auxiliary power transformers, boost circuit transformers, mobile device transformers, etc. They can also be used in electronic devices such as digital cameras and handheld switch power chargers.

Our Core Strengths:
Technology-driven, deep collaboration:
We have an experienced R&D and engineering team, proficient in high-frequency magnetism and dielectric material applications. From product selection, parameter optimization to simulation support, we can deeply participate in the customer's circuit design stage, providing customized solutions for various topologies such as LLC and PSFB, and responding quickly to prototype sample requirements.
Quality First, Full Control Throughout:
We have established a full-scale, refined quality control system from IQC (incoming inspection) to OQC (outgoing inspection). Every transformer and capacitor undergoes strict electrical performance tests (such as sensitivity, withstand voltage, insulation, loss, etc. ) to ensure the consistency and stability of the factory-produced products, in compliance with domestic and international safety standards.
Full Chain Services, Win-Win Cooperation:
We have constructed a complete service system covering "pre-sales - in-process sales - post-sales". Pre-sales provide professional consultation and value engineering analysis; in-process sales ensure transparent production and efficient delivery; post-sales offer rapid technical response, quality assurance, and long-term product lifecycle management. What we sell is not just products, but a reliable commitment and a lasting partnership.
Focus on Fields, Wide Application:
Our products are widely used in switching power supplies, photovoltaic/storage inverters, vehicle power supplies and charging facilities for new energy vehicles, communication base station power supplies, industrial control, and other cutting-edge fields, helping customers address industry challenges of efficiency, miniaturization, and intelligence.
