Enamel Coated Flat Magnet Wire

Product Description

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.
