Multifilar® Magnet Wire


Multifilar magnet wire

Four conductor 28 AWG heavy polynylon-155 Multifilar magnet wire in red, green, clear and blue.

Parallel bonded magnet wire for more consistent capacitance and impedance characteristics.

Where constant alignment of multiple strands is an advantage, Multifilar® magnet wire is the right choice. Its parallel-bonded, color-coded construction offers benefits for many applications.

Engineers should specify Multifilar® when concerned with space, weight and reliability. Where consistent capacitance and impedance characteristics are required, Multifilar magnet wire outperforms windings using two separate magnet wires.

Production users benefit from increased layer winding speeds, tighter windings that deliver more power in less space, reduced labor and handling. Color coding assists in conductor identification and reduces termination errors.

MWS Wire Industries custom manufactures Multifilar® magnet wire to assure flat, parallel construction in sizes AWG 16 and finer, and up to 20 conductors wide in some sizes.
