30 AWG PTFE / Teflon Insulated Wire
30 AWG PTFE wire has a conductor of about 0.05 sq mm and is used for electronics, instrumentation, sensor leads and avionics-style wiring where space and weight matter. PTFE (Teflon) is rated from −60°C to 250°C, does not burn easily, and resists nearly all chemicals, oils and solvents.
We build 30 AWG from 7 strands of 0.1 mm wire, following MIL-W-16878 / NEMA HP-3 style constructions. With the Type E (600 V) wall of about 0.25 mm the finished diameter is about 0.8 mm. Type ET (250 V) and Type EE (1000 V) walls are also available; the configurator recalculates the diameter and spark-test voltage for each grade.
Conductor choices are silver-plated copper (SPC), nickel-plated copper (NPC), bare copper, SS + copper and pure nickel. SPC is the usual choice up to 200°C for good solderability; NPC is preferred up to 250°C because nickel plating resists oxidation better at high temperature.
As a rough guide, 30 AWG PTFE wire carries about 2 A in free air. PTFE's thin wall lets it run cooler than thicker insulations of the same size, but bundling and high ambient still reduce the rating, so share your conditions for confirmation.
Choosing the right size: This is the smallest size in this range; for even finer wire, ask us about special constructions. If the current is near the limit, or the wire runs in a hot bundle, step up to 28 AWG PTFE Wire for extra margin. Under-sizing a high-temperature wire makes it run hotter, which shortens insulation life, so it is better to choose by current and ambient temperature together.
30 AWG PTFE PTFE wire is supplied on spools or drums in a wide range of colours, including striped colours for harness identification. For a quote, tell us the AWG or sq mm size, conductor plating, voltage grade, colour and total length.
Every batch is made at our Rewari factory and ships with a Material Test Certificate. Use the PTFE configurator to choose AWG or sq mm, conductor, voltage grade and colour and download a technical data sheet, or ask for a quote on WhatsApp.

Frequently asked questions
How many strands does 30 AWG PTFE wire have?
7 strands of 0.1 mm, giving about 0.05 sq mm.
SPC or NPC conductor — which should I choose?
SPC suits continuous use up to about 200°C and solders easily. NPC is preferred up to 250°C because it resists oxidation better.
What is the diameter of 30 AWG PTFE wire?
About 0.8 mm with the Type E 600 V wall. Type ET is thinner and Type EE is thicker.
Is PTFE wire made to MIL-W-16878?
Our constructions follow MIL-W-16878 / NEMA HP-3 style dimensions. Tell us if you need a specific approval and we will confirm what we can document.
