36 SWG Enameled Copper Wire: Specifications and Applications for High-Density Winding
May 14, 2024
In modern electronics and electrical engineering, copper winding wire is the “blood vessels” of key components such as inductors, transformers, motors, and relays. 36 SWG copper winding wire, due to its extremely fine diameter and excellent performance, plays an irreplaceable role in miniature and high-density electronic devices. I. Core Parameters 1. Wire Diameter and Cross-Sectional Area Copper core diameter: 0.193 mm (SWG standard). After enameling, the maximum outer diameter increases to 0.208 mm to ensure uniform insulation coverage. Cross-sectional area: Only 0.029 mm², equivalent to 1/4 the thickness of a human hair, suitable for high-density winding needs. 2. Electrical Performance DC resistance: As high as 606Ω/km, far exceeding that of thicker wire gauges (e.g., 14 AWG resistance is approximately 8.3Ω/km), making it suitable only for milliampere current scenarios. Current Carrying Capacity: Limited by the thin wire diameter, the continuous current carrying capacity does not exceed 100mA. Overcurrent can easily cause…
