One of the outstanding features of this ultra-fine enameled wire is its extremely small diameter. At only 0.03 mm thick, it is one of the thinnest wires on the market, making it ideal for applications where space is limited. This type of wire is particularly suitable for use in small devices such as watch coils, where accuracy and reliability are critical. The ultra-fine diameter ensures that the wire can be wound tightly and efficiently, maximizing the device's performance while minimizing its size.
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.
