Product Description

Product Description

Key Features of 0.03mm Enameled Copper Wire
Ultra-Fine Diameter
The wire measures 0.03mm (approximately 47 AWG), making it suitable for micro-scale repairs in compact devices like circuit boards, sensors, or medical instruments 6.

Litz Wire Construction
Some variants use a litz wire structure with 4000 strands, increasing surface area by 200-3400% compared to single-strand wires. This design enhances flexibility and reduces energy loss in high-frequency applications, ideal for transformers or RF instruments 6.

Insulation Properties
The wire is coated with enamel (e.g., polyurethane or polyester) to prevent short circuits. Certain types allow direct soldering without scraping the insulation, simplifying repairs 47.

Certifications and Standards
Complies with ROHS, UL, SGS, and ISO9001:2008, ensuring safety and reliability in professional settings 6.

Common Applications
Instrument and PCB Repairs
Used for bridging broken traces in precision electronics (e.g., motherboards, medical devices) due to its ability to fit into tight spaces without shorting adjacent components 46.

High-Frequency Transformers
The litz wire structure minimizes skin effect losses, making it suitable for transformers in RF equipment or power supplies 6.

Micro-Coil Winding
Applied in electromagnets, inductors, or miniature motors for scientific instruments 9.

Practical Considerations
Soldering Techniques
Requires higher soldering temperatures (350-400°C) to melt the enamel coating. Pre-tinning the wire with a hot iron ensures reliable connections 34.

Handling Challenges
Due to its extreme thinness, specialized tools (e.g., magnifiers, fine-tip tweezers) are recommended to avoid breakage during installation 7.
