Custom litz wire (served / twisted enameled): strand diameter 0.05–0.50 mm, thermal class 130–220, built from your drawing or physical sample. Trial and prototype quantities are welcome. Quote with the strand calculation, usually within 48 hours.
From single strand diameter to batch lead time, in one table
| Category | Capability |
|---|---|
| Litz wire · strand diameter | 0.05–0.50 mm (high-frequency builds typically 0.05–0.10) |
| Litz wire · strand count | 20–1000+ strands, calculated from operating frequency |
| Litz wire · insulation | Polyurethane (QA) / polyester-imide (QZY) / polyamide-imide (QXY) / self-bonding |
| Thermal class | 130 / 155 / 180 / 200 / 220 |
| Construction | Single bunched or multi-bundle (re-twisted), served / yarn-covered outer protection |
| Lead time | 7–10 days standard constructions; re-twisted within 15 days — confirmed in writing before order |
Send us these four inputs and we do the rest — or run the rough numbers yourself
Set the single-strand diameter on the skin-depth scale of your operating frequency. Higher frequency, finer strand.
Set total copper cross-section from rated current; 3–6 A/mm² is typical at high frequency, tightened against your temperature-rise target.
Total cross-section ÷ single-strand area = strand count, rounded up to a standard construction.
Verify the bunched outer diameter and slot fill factor — it must fit and wind cleanly.
TX / RX coils in litz wire — lower AC loss from skin effect at high frequency.
Custom high-frequency work coils, thermal-shock resistant insulation systems.
Switch-mode power supply and inverter transformer windings.
Compact, repeatable windings for sensors and small-batch instruments.
