QA-180

Ultra-Fine Enameled Copper Round Wire – Class 180, Solderable Directly, Polyurethane (UEWH), for High-Temperature Miniature Coils

QA-180 is a high-performance ultra-fine polyurethane enameled copper wire with direct solderability – the insulation layer can be soldered through without pre-stripping. This unique feature makes it ideal for high-speed automated winding and soldering processes in miniature electronic applications requiring enhanced thermal endurance.

With a thermal class of 180°C (Class H), QA-180 offers a significant thermal advantage over standard Class 155 wires. Available in ultra-fine diameters from 0.02 mm to 0.12 mm, this wire is the perfect choice for precision coils in demanding automotive electronics, industrial sensors, power supplies, and other compact devices where both space and temperature are constraints.

The polyurethane insulation provides excellent solderability at typical soldering temperatures while maintaining Class H thermal performance, eliminating the need for mechanical or chemical stripping and enabling efficient, reliable, and cost-effective manufacturing.
