Enameled wire or magnet wire contains the following elements：
Conductor type: The conductor is the basic material of the enameled wire. Commonly used materials for conductors are copper, aluminum and Copper-silver alloy, copper-tin alloy, copper-nickel alloy, copper-zinc alloy and other alloy materials. Usually the resistance in an electronic component is determined by the conductor. The cross-sectional area and length of the conductor affect the resistance.
The type of insulating film: The insulating film is divided into single film and heavy film. Single film includes UEW, PEW, EIWHE AIW etc. Heavy film refers to an additional coating of nylon or self-adhesive paint on a single film.
The thickness of the coating is the thickness of the insulating paint on the conductor. The coating thickness is classified and defined by NEMA, MW1000, JISC3202, and IEC60317 standards. The thickness of the coating determines the pressure level of the enameled wire.
Thermal rating refers to the heat resistance level of the enameled wire, showing the temperature index, softening breakdown and thermal shock, etc. It is defined by the NEMA, MW1000, JISC3202, and IEC60317 standards. Thermal rating are 130, 155, 180, 200, 220, 240.
