Solid Conductor Ei 4.0mm*0.4mm Rectangular Copper Wire

EI / AIW Class 220 4.0mm*0.4mm Flat Enameled Winding Wire Rectangular Copper Wire

Meet design requirement of lower height, smaller size, lighter and more power.The wire is widely used in electronice, military electronic, spaceflight.

Bigger surface area than round wire at the same cross section, reducce skin effect effectively, decrease current loss, that/s better to adpat high frequency transduction.

High space factor and fill in ratio, greatly reduce 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 environment anti EMI, small vibration, low noise and install in high density.

RUIYUAN was established in 2002, located in Tianjin City,the second largest port city in China.We have been focusing on different kinds of high quality wires: enameled round copper wire, rectangular enameled copper triple insulated wire, silk covered Litz wire, bonding wire and special enameled wire for 23 years.Ruiyuan is one of the pioneers in producing micro thin enameled wires below 0.03mm in China. Our R & D team has 20 years of market experience. In 2019, our finest diameter is 0.011mm, and mass production has been achieved. All of our products are UL, RoHS certified, in line with industry standards IEC60317, JIS C 3202, NEMA, NW82.
