2UEW-F Super fine 0.03mmx2000 high frequency litz wire for transformer
In the field of electrical engineering, the choice of wire has a significant impact on the performance and efficiency of equipment, especially in high-frequency applications. Our company is proud to introduce a custom high-frequency copper litz wire designed to meet the demanding requirements of transformer winding. This innovative product is made of enameled copper wire with a wire diameter of only 0.03 mm. Our litz wire is twisted with 2000 strands, which not only improves conductivity but also minimizes skin effect and proximity effect, making it an ideal choice for high-frequency applications.
A key benefit of our high-frequency copper stranded wire is its ease of soldering. This feature simplifies the assembly process and enables efficient and reliable connections in transformer winding applications. Our dedicated technical team is always available to provide support and guidance to ensure you get the most out of our products. We understand that every project is unique, so we offer small batch customization services with a minimum order quantity of only 10 kg. This flexibility allows you to customize orders to your specific needs without the burden of excess inventory.
