MAIKE is specialized in the design and manufacture of high-quality customized planar transformers and inductors. The factory is based in Mianyang which is the only National Science & Technology city in China and is strategically placed to service the global electronics market. We design and manufacture for a variety of end-user applications ranging from Welding to Aerospace & Automotive & Battery Charging etc. The planar transformer is a transformer with high frequency, low profile, small height, and high operating frequency. Compared with conventional transformers, the size of the magnetic core of planar transformers is greatly reduced, especially when the height is reduced the most. This feature is very attractive in power supply equipment where space is strictly limited, making it the preferred magnetic component in many power supply equipment. The structural advantages of planar transformers also bring many advantages to its electrical characteristics: high power density, high efficiency, low leakage inductance, good heat dissipation, and low cost. Key Features-- (1) High current density. The wires of a planar transformer are actually planar conductors, so the current density is high. (2) High efficiency. The efficiency can reach 98%~99%. (3) Low leakage inductance. Approximately 0.2% of the primary inductance. (4) Good heat conduction. The hot aisle distance is short and the temperature rise is low. (5) Low EMI radiation. Good core shielding can keep radiation to a very low level. (6) Small size. The use of a small magnetic core can reduce the size accordingly. (7) The parameters have good repeatability. Because the winding structure is fixed and easy to pre-process, the parameters are stable. (8) Wide operating frequency range. The frequency can be from 50kHz to 2MHz. (9) Wide operating temperature range. The working temperature is -40 130. (10) Good insulation. The planar transformer is composed of overlapping conductive circuits and insulating sheets, thereby ensuring up to 4 kV insulation isolation between windings, primary-secondary and secondary-secondary.

Our dry-type transformers, also known as "dry transformers," are designed to provide efficient and reliable electrical power distribution. These transformers use air or resin as the cooling medium instead of traditional oil. This design minimizes the risk of environmental contamination and allows for safe operation in various settings. Key features of our dry-type transformers include: 1. **Safety and Environmental Friendliness:** As there is no oil involved, the risk of fire and environmental impact is significantly reduced. This makes them a safer and more environmentally friendly option. 2. **Versatility:** Dry-type transformers are suitable for a wide range of applications, including industrial facilities, commercial buildings, and residential areas. They can be customized to meet specific voltage and power requirements. 3. **Low Maintenance:** These transformers generally require lower maintenance compared to oil-filled transformers, resulting in cost savings over their lifecycle. 4. **Compact Design:** The absence of oil allows for a more compact and lightweight design, making them easier to install and suitable for locations with space constraints. 5. **Efficiency:** Our dry-type transformers are designed for high efficiency, ensuring minimal energy loss during power distribution. Whether for upgrading existing infrastructure or implementing new projects, our dry-type transformers are engineered to deliver optimal performance, reliability, and safety in diverse electrical applications.
