Ultra-thin 0.5x0.03mm Flat Enameled Copper Wire

Ultra-thin AIW 220 °C 0.5×0.03 mm flat enameled copper wire, engineered for compact, high-frequency and high-power designs. Custom self-bondable AIW flat enameled copper wire options are also available.

• Thickness: 0.02 mm – 3.00 mm
• Width: 0.15 mm – 18.00 mm
• Width-to-thickness ratio: up to 1:30

• Meets design requirements for lower height, smaller size, lighter weight and higher power output.
• Widely used in electronics, electrical applications, motors, network communication, smart home, new energy, automotive electronics, medical electronics and aerospace.
• Larger surface area than round wire at the same cross-section, effectively reducing skin effect and current loss for better high-frequency transmission.
• High space factor and fill-in ratio greatly reduce resistance, carry higher current and deliver a higher Q value for high-current loads.
• Rectangular wire construction offers simple structure, good heat dissipation, stable performance and consistent quality.
• Maintains stable temperature-rise current and saturation current in high-frequency and high-temperature environments, with anti-EMI performance, low vibration, low noise and high-density installation.

Up to 97 % fill-in ratio for compact, high-efficiency coil and winding designs.

The insulation thickness at the corners is similar to that of the flat surface, making it easier to maintain insulation integrity after bending.

• 120 °C flat enameled wire for oil-immersed transformers.
• 130 °C, 155 °C and 180 °C flat enameled wire widely used in all kinds of magnet coils.
• 200 °C flat enameled wire for continuous operation at high temperature.
• 240 °C flat enameled wire for magnet coils in aviation and marine applications.

Our factory covers more than 8,000 m² and is divided into two facilities: a wire drawing factory and a wire enamelling factory. With 200 experienced staff and 7 core quality control systems, our high quality has been confirmed by external auditors repeatedly across numerous certificates.

We currently hold four national invention patents and ten national know-how items covering core technologies in production equipment design and manufacture, product R&D and crafting standard establishment. The company also has high-standard capabilities in analyzing the mechanical, electrical, heat-proof and erosion-proof functions of wire coatings, as well as application performance. Our strong R&D team includes members with 8 years of experience, some with over 20 years, ensuring our products remain innovative and consistently high in quality. We continue to pursue product innovation and welcome joint market research and development with our clients.

Rvyuan has partnered with many famous brands and companies worldwide, including TDK Lambda, Samsung and Hitachi Energy, covering a wide range of wire products such as Litz wire, rectangular enameled copper wire, TIW wire, FIW wire and special alloy wire. We also help small to large enterprises achieve their business goals. For small and medium-sized businesses, we provide delicate custom service from project start to finish and a reasonable minimum sale quantity for custom designs. Always customer-oriented, we are committed to providing top-quality products to facilitate your business.
