Engineered Reliability for Global Power Electronics
Dezhou Xinping Electronics (xptransformer.com) delivers high-performance magnetic solutions tailored to the strict parameters required by design engineers and B2B procurement professionals worldwide.
Over 20 Years of Specialized Magnetic Manufacturing Experience
At Dezhou Xinping Electronics, we design and manufacture high frequency transformers and custom inductive components that serve as the backbone of modern power conversion. We understand that purchasing engineers and factory buyers require not just parts, but absolute parameter consistency, long-term thermal stability, and full regulatory compliance.
Our state-of-the-art facility utilizes full-automatic winding machines to guarantee precise tension control and turn-count accuracy. This rigorous production control minimizes leakage inductance and parasitic capacitance, ensuring your LLC resonant, flyback, or push-pull topologies operate at peak efficiency.
From initial custom prototyping to high-volume OEM/ODM production runs, our engineering team works directly from your datasheets or schematic drawings to deliver optimized magnetic solutions.

Engineered to Outperform: Technical Advantages
Every Dezhou Xinping transformer is optimized for electrical integrity, thermal dissipation, and long-term operating life in demanding environments.
■ Ultra-Low Leakage Inductance
By implementing advanced sandwich winding techniques and precise geometric alignment of primary and secondary windings, we reduce leakage inductance to less than 1% of the magnetizing inductance. This directly improves conversion efficiency and protects your switching MOSFETs from high-voltage spikes.
■ Screen Printed White Varnish Technology
Our proprietary screen printed varnish transformer coating provides superior environmental sealing. The white varnish layer acts as an advanced barrier against moisture ingress, dust, and corrosive gases while improving thermal radiation from the winding assembly.
■ Patented Cooling Winding Design
We hold a specialized utility patent for a cooling winding configuration. This unique construction optimizes internal airflow and heat transfer paths, lowering the hotspot temperature of the transformer by up to 15°C compared to conventional winding structures.
■ Robust PCB Mount Mechanical Design
Designed to withstand high vibration profiles, our robust pin layouts and customized headers prevent solder joint fatigue. Perfect for automotive sub-assemblies and industrial machinery where mechanical shock is common.
■ Broad Operating Temperature Range
Utilizing premium grade ferrite cores and high-temp magnet wire, our transformers are rated for continuous operation from -40°C up to +70°C ambient temperature (with thermal classes up to Class B 130°C / Class F 155°C optionally available).
■ 100% Pre-Shipment Parametric Testing
Every production batch undergoes automated electrical testing. We measure inductance, turns ratio, leakage inductance, DC resistance (DCR), and dielectric strength (hipot) before the components leave our warehouse.
