High-performance magnet wire engineered for precision electrical applications. This 900-gram spool delivers approximately 24,324 meters of AWG 41 enameled copper wire with a 0.07mm diameter, featuring single Formix insulation for superior thermal and chemical resistance. The ultra-fine gauge makes it ideal for intricate coil winding, transformers, and compact motor designs where space efficiency matters. Formix enamel coating ensures excellent dielectric strength and durability under demanding conditions. Perfect for electronics manufacturers, repair specialists, and hobbyists requiring consistent, high-quality wire for reliable performance in tight-tolerance projects. Magnet Wire AWG 41 0.07 mm Heavy Formvar boasts an even thinner diameter compared to the AWG 40 versions you described previously. This translates to some key advantages: Ultra-Fine Size (0.07 mm): This wire achieves the absolute pinnacle of thinness within the AWG 41 range. It allows for the tightest coil formations ever, enabling the most significant size reduction possible for your electronic devices. Unmatched Packing Density: With its minuscule diameter, you can squeeze in the most windings per square millimeter, maximizing efficiency and pushing component performance to new heights. Heavy Formvar Insulation Advantage: As with the AWG 40 version, the superior thermal stability, electrical strength, and mechanical resilience ensure reliable operation even in demanding environments. However, it’s important to consider the trade-offs inherent in such a fine wire: Increased Fragility: Due to its extreme thinness, AWG 41 0.07 mm wire is more delicate and prone to breakage during handling and winding. This necessitates extra care and potentially specialized winding equipment. Current Carrying Capacity: The thinner the wire, the less current it can safely carry. Ensure your application’s current requirements are compatible with this wire size. Applications: This wire is ideal for situations where absolute miniaturization is paramount, such as: Micromotors: Achieve unparalleled power density in tiny motors for drones, miniature robots, and medical devices. High-Frequency Transformers: The exceptional packing density allows for the creation of ultra-compact, high-frequency transformers for advanced electronics. Micro-Inductors: Design miniature inductors for high-performance circuits in a fraction of the space. Choosing the Right Wire: While AWG 41 0.07 mm Heavy Formvar offers unmatched miniaturization potential, carefully evaluate your specific needs. If your application prioritizes ease of handling or requires higher current capacity, consider the slightly thicker AWG 40 options you described earlier. We recommend consulting with our technical team to determine the optimal wire size for your project. They can help you balance the benefits of miniaturization with the practical considerations of handling and current requirements.
