QA-1/180-0.039 Enameled Copper Wire

Polyurethane Class H (180°C) · Ultra-Fine for Micro Coils

QA-1/180-0.039: Engineered for Extreme Miniaturization

With a conductor diameter of 0.039mm, this Grade 1 polyurethane enameled copper wire is purpose-built for next-generation microelectronics. The Class 180 thermal rating ensures reliability in compact transformers, hearing aid coils, micro actuators, and fine-pitch voice coils. Grade 1 insulation minimizes outer diameter — essential for tight winding windows — while polyurethane chemistry enables direct soldering without stripping, streamlining automated assembly.

⚡ For 0.039mm ultra-fine wire, Grade 1 OD is ≤0.050mm — a critical advantage for high-density micro-coil designs. Solderability and 180°C thermal stability verified by IEC pin-hole testing.

Micro-Wire Engineering

Achieving consistent quality at 0.039mm requires specialized manufacturing expertise. CHINGCUNG employs ultra-fine drawing lines with continuous annealing to produce a copper core with exceptional circularity and surface finish. The polyurethane insulation is applied using laser-monitored concentric coating, ensuring Grade 1 uniformity and zero defect density. QA-1/180-0.039 is formulated for micro-coils operating at elevated temperatures (up to 180°C), where conventional polyester wires exhibit premature failure. Minimal pinhole counts preserve breakdown voltage integrity even under winding stress.

✦ Micro-Scale Advantages: Direct solderability eliminates risky mechanical stripping — vital for fragile ultra-fine wires. Class 180 thermal rating supports higher power density in compact form factors. Grade 1 outer diameter (max 0.048mm) maximizes copper fill factor, improving coil efficiency in volume-constrained applications. Superior windability reduces breakage during high-speed winding, boosting production yield.

✦ Quality Assurance: Every spool of QA-1/180-0.039 undergoes 100% pin-hole detection, continuity verification, and laser dimensional inspection. Our ISO Class 7 clean-room environment eliminates contamination risks. Full material traceability from copper rod to finished spool supports medical, automotive, and aerospace qualification requirements.

FAQs – QA-1/180-0.039

  • Q1: Is 0.039mm enameled wire difficult to wind?
    A: QA-1/180-0.039 offers excellent tensile strength for its gauge. We recommend optimized tension settings and wire guide systems; our technical team provides detailed winding parameters.
  • Q2: Can it be soldered without stripping?
    A: Yes. Dip the wire end into solder at 400°C for 1–2 seconds — the polyurethane coating decomposes, leaving a clean, tinned surface.
  • Q3: What is the breakdown voltage for 0.039mm Grade 1?
    A: Typically ≥250V DC, meeting IEC standards for micro transformers and miniature coils.
  • Q4: Are sample spools available?
    A: Yes, sample spools (500g, 1Kg) are available for engineering qualification. Lead time 7–10 days.
  • Q5: What packaging protects ultra-fine wire?
    A: Anti-static PL-2 plastic spools with soft winding layers. Vacuum-sealed moisture barrier bags are available for long-term storage.
