CLASS 155 / 180 / 220 SELF BONDING WIRE ENAMELED COPPER WINDING
WIRE FOR VOICE COIL
We are one of the pioneers in producing ultra-fine enameled wires
below 0.03mm in China. Our R & D team has 20 years of market
experience.We have achieved the goal of "zero pinholes after
stretching" for ten years. In 2019, our finest diameter is 0.011mm,
and mass production has been achieved.When the displays return the
transformer industry, we are the No.1 Chinese brand with a share of
cake.We rival the internationally renowned enameled wire brands for
production, technology, raw materials.We surpass them in terms of
"service, quick response"; 30% lower "price" is our advantage. More
and more well-known customers choose us as suppliers-Philips,
Bosch, Panasonic, Samsung ...We have a long history of producing
self-adhesive lines. Since the beginning of our factory, we have
started to develop and produce self-adhesive lines.Because of our
strong R & D strength, our products have a wide range of
applicationsWe have a full range of self-adhesive lines and a wide
range of applicationsThermal class is155C, 180 C, 200 C, 220
C.Conductor material includes enameled round wire, enameled
copper-clad aluminum wire
APPLICATION
Speaker coil, such as microphone, earphone, speaker, hearing
aid,Bluetooth audio, speakers, etc.;High-temperature voice coils,
such as car audio, home theater, high-power speakers, etc.
High-sensitivity voice coils, such as headphone speakers and
high-temperature-resistant voice coils;micro vibration motor,such
as focus-driving,(coin-type, coreless-type) and other electrical
and electronics components, such as inductor, watch coil, coin
machine coil, buzzer;magnetic head, IC card.
FEATURES
Very good solderability that can be soldered without removal of
coating.
Small tg δ value under high frequency electronic apparatus.
Easy to be dyed to different colors for identifying purpose when
soldered.
High breakdown voltage, small dielectric loss angle
