Product Description

2UEW-F 0.05mm Polyurethane Enameled Copper Wire For Miniature Inductors

0.05mm polyurethane enameled copper wire is an extremely fine special enameled wire that combines the properties of polyurethane coating and copper conductor, and has important applications in the field of precision electronics.

Advantages of Enameled Copper Wire

Extremely Fine Diameter and High Flexibility: With a diameter of only 0.05mm (approximately half the thickness of a human hair), it is suitable for ultra-high density winding.
Small Bending Radius, Easy to Precision Winding: Ideal for miniature coil applications.
Direct Solderability: Can be directly soldered at approximately 370°C without scraping off the coating ("self-soldering" characteristic), simplifying the processing of miniature coils.
High Frequency Resistance: Low dielectric loss at high frequencies, suitable for high-frequency transformers and RF coils.
Chemical Resistance: Resistant to solvents and moisture, with good stability.
Electrical and Mechanical Properties: The copper conductor has good conductivity, and the coating has high insulation strength (withstand voltage typically exceeding 1kV).
Strong Coating Adhesion: Scratch resistant, and not easily damaged during winding.
