Description

Overview

Ultra-fine enameled copper wire in diameters from 0.03mm to 0.09mm, sold by length rather than by weight because such fine gauges are impractical to weigh accurately. Used where a coil needs many turns in a very small winding window.

Specifications

  • Available diameters: 0.03 / 0.05 / 0.06 / 0.07 / 0.08 / 0.09 mm
  • Sold by length: 0.03mm — 10000m; 0.05–0.07mm — 2000m; 0.08–0.09mm — 1000m
  • Conductor: enameled copper
  • Application: magnet coil winding

Purpose

At these gauges the wire is finer than a human hair. The point is packing: a 0.03mm wire allows an enormous turn count inside a tiny bobbin, which is how small sensors, micro-motors and instrument coils achieve their sensitivity in the space available.

Applications

  • Instrument and meter coils
  • Small sensors and pickups
  • Micro-motors and vibration motors
  • Voice coils and small relays
  • High-turn-count laboratory electromagnets

How to Use

  1. Choose the finest gauge that still carries your current — finer wire means more turns but more resistance.
  2. Wind slowly with light, constant tension; these gauges break easily and kink permanently.
  3. Terminate by soldering at a temperature high enough to burn back the enamel, or strip very carefully.
  4. Insulate the finished coil and avoid sharp edges on the bobbin, which cut through the thin film.
