The China EE16 Automotive Electronic High-Frequency Transformer produced by Haoer manufacturer features small size, low price and high reliability. The EE type transformer is a basic ferrite core type, with stable performance, low cost and large current. It is widely used in power conversion and line filtering. The volume ranges from small to large, meeting the requirements of various application circuits. If the insulated wire with temperature resistance of 155℃ or 180℃ is used, it can meet different temperature conditions and is suitable for various switching power supplies, inverters, UPS, etc.
The EE16 high-frequency transformer is commonly used in auxiliary power transformers, DC-DC converters, driving transformers, digital cameras, handheld switch power chargers, etc.
The EE16 Automotive Electronic High-Frequency Transformer produced by Haoer Company are made from high-quality high-frequency soft ferrite magnetic materials, featuring high magnetic permeability, high saturation flux density and low power loss. The products can meet UL, CE, VDE, CQC and other standards according to customer requirements
The evolution of electronic devices has driven a parallel shift in spatial and energy demands: from initial miniaturization, through a phase of high power consumption, to the current era prioritizing energy efficiency and environmental sustainability. This progression reflects an industry-wide pursuit of excellence, particularly in enhancing electrical conversion efficiency and expanding operational voltage ranges. A landmark innovation in this journey is the widespread adoption of high-frequency transformers, which have superseded bulky industrial-frequency counterparts. Their substantially reduced weight and superior performance render them indispensable for the future of DC-powered electronics.
Our company specializes in the manufacturing of high-frequency transformers utilizing advanced soft ferrite cores, distinguished by their high magnetic permeability, high saturation flux density, and minimal core losses. We engineer our products to comply with major international safety standards, including UL, CE, VDE, and CQC, tailored to client specifications. Offering comprehensive custom design services, our portfolio encompasses a wide array of core shapes such as EI, EE, EEL, EC, ER, PQ, RM, EFD, EP, EPC, EF, ED, and ETD to meet diverse application needs.
The EE16 Automotive Electronic High-Frequency Transformer demonstrates outstanding and broad technical indicators in both electrical performance and environmental adaptability. Its core operating frequency ranges from 20kHz to 500kHz, enabling it to flexibly adapt to various application scenarios from basic switching power supplies to high-end precision electronic equipment, while enhancing power conversion efficiency and effectively optimizing power density.
In terms of power output capacity, the product range is complete, with output power covering 0.5W to 1000W, providing stable and reliable power conversion solutions for various devices ranging from miniature consumer electronics to industrial-grade power modules.
The product has an excellent operating temperature range (-40℃ ~ +125℃), ensuring its stable operation even in extreme cold or hot environments. Its storage temperature requirement is -25℃ to +85℃, and the storage humidity environment is 30% to 95%. This guarantees that the internal magnetic core and coil structure of the product remain unaffected by temperature and humidity changes during storage, transportation, and other non-operational states, maintaining consistent performance and safety over the long term.
