40 AWG 0.08mm Enameled Wire Winding Insulated Solid
40 AWG 0.08mm Enameled Wire Winding Insulated Solid
Like other wire, magnet wire is classified by diameter (AWG number, SWG or millimeters) or area (square millimeters), temperature class, and insulation class.
types: Grade 1, Grade 2 and Grade 3. Higher grades have thicker insulation and thus higher breakdown voltages.
The temperature class indicates the temperature of the wire at which it has a 20,000 hour service life. At lower temperatures the service life of the wire is longer (about a factor of two for every 10 °C lower temperature). Common temperature classes are 105 °C (221 °F), 130 °C (266 °F), 155 °C (311 °F), 180 °C (356 °F) and 220 °C (428 °F).
