3.5 mm * 0.4 mm Class 220 AIW Flat Magnet Wire Enameled Rectangular
Copper Wire
Meet design requirement of lower height, smaller size, lighter and
more power. The wire is widely used in electronics, electric
application, motor, network communication, smart home, new energy,
automobile electronic, medical electronic, military electronic,
spaceflight.
Bigger surface area than round wire at the same cross section,
recduce skin effect effectively, decrease current loss, that’s
better to adpat high frequency transduction.
High space factor and fill in ratio, greatly recduce resistance,
pass bigger current, get higher Q value that is better to adapt
high current load.
The product that use rectangular wire has such features: simple in
structures, good heat dissipation, stable performance, stablegood
consistency. Maintain stable temperature rise current and
saturation current in high frequency and high temperature
environmnet anti EMI, small vibration, low noise and install in
gigh density.
