Microsquare® Magnet Wire
Miniature square (Microsquare) and rectangular magnet wire for specialty coil and motor windings.
When product miniaturization calls for tighter dimensional specifications, MWS Microsquare Film-Coated Magnet Wire allows design engineers to create compact coils and small motors that deliver more power in less space.
Microsquare means miniature square and rectangular, copper and aluminum magnet wire.
Custom-produced by MWS in sizes smaller than 14 AWG or 3500 sq. mil. cross-sectional area, Microsquare is available in a wide range of solderable and high-temperature insulations and a variety of colors, with or without bondable overcoats.
See our Magnet Wire Insulation Guide for information on film insulations and our Bondable Magnet Wire page for more information on the bondable overcoats.
Microsquare Magnet Wire was developed to provide improved winding uniformity and maximum use of space
