Custom Enamelled Copper Wire Solderable Winding Wire For Electronic Products
The polyurethane enamel coating on this wire is another key feature that sets it apart. This coating provides excellent insulation, ensuring the wire can withstand high temperatures without degrading.
With a standard temperature rating of 155 degrees Celsius and an optional upgrade to 180 degrees Celsius, the wire operates reliably in even the most demanding conditions. This makes it an excellent choice for applications such as headphone cables and tablets where durability and performance are critical.
