2UEW 180 0.03mm Size Enamel Round Copper Wire Specifications 

Main Features of ultra-fine enameled copper wire

• Ultra-fine 0.03 mm conductor – Enables miniature coil windings in smartphones, wearables, micro motors, and other space-critical devices where conventional wire diameters cannot fit.
• 180 °C (Class H) thermal endurance – Rated for continuous high-temperature operation, making the wire suitable for sealed motors and other heat-constrained applications.
• Heavy (Grade 2) polyester insulation – Provides high dielectric strength, good flexibility, and mechanical protection during winding, while maintaining a thin overall envelope.
• TU2 oxygen-free copper conductor – Offers stable electrical conductivity and effective heat dissipation, supporting consistent performance in precision instruments and high-frequency devices.
• International standard compliance – Manufactured and tested in accordance with the IEC 60317 and GB/T 6109 winding-wire series; each parameter (elongation, spring-back, flexibility, heat shock, cut-through resistance, breakdown voltage, scratch resistance) is verified per IEC 60851 before shipment.
• Flexible supply options – Available in 5 kg plastic reels with customized spooling, packaging, and export documentation for global buyers.

FAQ

Q1: What is the maximum continuous operating temperature of this wire?

A: The 2UEW-180 grade is rated for continuous operation at 180 °C (Class H). For higher temperature classes up to 220 °C, please contact our sales team for alternative enameled wire grades.

Q2: What does "heavy" insulation thickness mean for a 0.03 mm wire?

A: It refers to Grade 2 (G2) insulation build as defined in the IEC 60317 / GB/T 6109 series - a thicker insulation layer than Grade 1, providing higher dielectric strength while remaining suitable for ultra-fine winding applications.

Q3: Which standards is this 0.03 mm enameled wire manufactured to?

A: The wire is manufactured to the GB/T 6109 series and IEC 60317 series, and each batch is tested per IEC 60851. UL certification is available on request.

Q4: How is the wire packed and shipped?

A: Standard packing is 5 kg per plastic reel. Custom spooling, carton specifications, and export packing for sea or air freight can be arranged to protect the ultra-fine wire during transit.

Q5: What are the typical applications for 0.03 mm enameled copper wire?

A: Speaker and voice coils, micro motor windings, sensors, medical devices, communication coils, RF circuits, and precision instruments - anywhere compact, precise winding is essential.

Q6: Can GNEE supply customized spooling or longer continuous lengths?

A: Yes. Please provide your required spool weight, inner/outer reel dimensions, and target application; our engineering team will confirm feasibility and lead time within 24 hours.
