QA polyurethane enameled wire: The thermal grade is F grade 155 °C, the biggest feature is the direct weldability, high frequency performance, easy coloring, good moisture resistance, mainly used in communications, audio, relays, small transformers and household appliances.
Product features: QA polyurethane enameled wire has an unparalleled superiority of other types of enameled wire, that is,
360 ° C ~ 400 ° C has good solderability.
Know-how friends know that because of the insulation of the paint, the enameled wire needs to scrape off the paint of the solder part during the soldering to ensure its electrical conductivity. This scraping process increases both the cost and the time, and encounters the fine enameled wire. When it is touched, the squeegee is a technical activity, so on this basis, the straight-welded enameled wire came into being. The so-called direct soldering property is a property that the enameled wire does not need to be directly soldered when soldering. He greatly enhanced the flexibility of the customer’s winding coils, and saved costs, so it won wide acclaim after launch.
Uses: Widely used in high-frequency transformers, inductor coils, relays, motors, electrical instrument coil windings with long-term operating temperature below 155 °C.
UEW is a Japanese standard representation. Both Taiwanese and Korean capital are represented by UEW. QA is a representation of national standards and international standards. The difference between the two is that the outer diameter of UEW is relatively loose, and the others are basically the same. Note: 2UEW=QA-1 1UEW=QA-2
Q in QA-1 is the serial number, the first pinyin of the paint.
A is the first pinyin of polyurethane paint, ammonia.
-1 stands for thin paint film, -2 stands for thick paint film, and -3 stands for thick paint film.
